摘要

A display device includes a substrate including a display area and a non-display area adjacent to the display area, lower pads disposed in the non-display area of the substrate and spaced apart from each other, upper pads disposed on the lower pads and spaced apart from each other, an anisotropic conductive film disposed between the lower pads and the upper pads, and a circuit film disposed on the upper pads, the circuit film including first lower holes disposed between the upper pads in a plan view, and first upper holes connected to the first lower holes and having radiuses larger than radiuses of the first lower holes. The first upper holes form first openings on an upper surface of the circuit film. A method of manufacturing the display device is provided.

The wires 400a may be disposed on the non-display area NDA of the substrate 100. The wires 400a may be disposed between the display area DA and the integrated circuit 200. The wires 400a may electrically connect the integrated circuit 200 disposed in the non-display area NDA and the pixels 500 disposed in the display area DA. The wires 400a may include data signal wires, gate signal wires, emission control signal wires, gate initialization signal wires, initialization voltage wires, power supply voltage wires, and the like

The lower pads 110 may be disposed on the non-display area NDA of the substrate 100. The lower pads 110 may be disposed in the first direction DR1 from the integrated circuit 200. The lower pads 110 may include a conductive material. The anisotropic conductive film 120 may be disposed on the lower pads 110. The upper pads 130 may be disposed on the anisotropic conductive film 120. The upper pads 130 may include the conductive material. The circuit film 140 may be disposed on the upper pads 130. The circuit film 140 may provide the signals to the display area DA. In an embodiment, the circuit film 140 may include a flexible printed circuit board (FPCB). When the flexible printed circuit board is bent, a bezel area of the display device 1000 may be reduced. In an embodiment, the circuit film 140 may include a polyimide film.
