摘要

A display device includes a substrate having a first surface, a second surface opposite to the first surface, a first non-bendable area, a second non-bendable area, and a bendable area, a display module disposed on the first surface of the substrate, a first protection film disposed on the second surface of the substrate to correspond to the first non-bending area, and a second protection film that differs from the first protection film disposed on the second surface of the substrate to correspond to the second non-bending area, where the first non-bendable area and the second non-bendable area are separated from each other with the bendable area in between.

CROSS-REFERENCE TO RELATED APPLICATIONS

This U.S. non-provisional patent Applications claims priority under 35 U.S.C. § 119 from, and the benefit of Korean Patent Application No. 10-2019-0094683, filed on Aug. 5, 2019 in the Korean Intellectual Property Office, the contents of which are herein incorporated by reference in their entirety.

BACKGROUND Technical Field

Exemplary embodiments of the present invention are directed to a display device.

Discussion of the Related Art

Various display devices that are used in multi-media devices such as televisions, mobile phones, tablet computers, navigators, or game players, are being developed. A display device includes a display module disposed on a substrate. The substrate of the display device is electrically connected to a circuit board that provides driving signals.

Pads for electrical connection to the circuit board and other components are arranged in a non-display area on the substrate. When a display area is to be located on one entire surface of the display device, the non-display area on which the pads and other components are arranged should be minimized.

Nowadays, efforts to reduce the area of the non-display area of the display device are directed to bending a part of the substrate.

SUMMARY

Embodiments of the present disclosure provide a display device in which a part of a substrate is bendable, and a manufacturing method thereof.

權(quán)利要求

1
What is claimed is:1. A method of manufacturing a display device, the manufacturing; method comprising:providing a display panel that includes a first non-bendable area, a second non-bendable area, and a bendable area;disposing a first adhesive layer on a second surface of the display panel at a position that corresponds to the first non-bendable area,disposing a second adhesive layer on the second surface of the display panel at a position that corresponds to the second non-bendable area,wherein disposing the first adhesive layer and disposing the second adhesive layer comprises:providing a display component that includes a first liner that includes a first area, a second area separate from the first area by a predetermined distance, and a third area between the first area and the second area, wherein the first area and the second area are directly connected to each other through the third area,disposing the first adhesive layer on the first area of the first liner,disposing the second adhesive layer on the second area of the first liner, anddisposing a second liner on the first adhesive layer and the second adhesive layer;disposing a first protection film base on the first adhesive layer,disposing a second protection film base that differs from the first protection film base on the second adhesive layer;disposing a third protection film on a first surface of the display panel that is opposite ter the second surface,wherein the first non-bendable area and the second non-bendable area are separated from each other with the bendable area in between, and the third protection film covers the first non-bendable area, the second non-bendable area, and the bendable area; andremoving the third protection film front the first surface of the display panel during a subsequent manufacturing process of the display panel.2. The manufacturing method of claim 1, wherein the first protection film base comprises glass.3. The manufacturing method of claim 1, wherein the second protection film base comprises polyimide.4. The manufacturing method of claim 1, further comprising:removing the first liner of the display component;attaching the first adhesive layer and the second adhesive layer to the second surface of the display panel; andremoving the second liner of the display component.5. The manufacturing method of claim 4, wherein the first adhesive layer and the second adhesive layer include an identical material.
