摘要

A display panel including: a display region including pixels and a non-display region, each pixel including an emission element including a first electrode, an emission layer, and a second electrode; a pixel definition layer including a first opening; a first encapsulation layer on the pixel definition layer and overlapping the emission element; a partition wall on the first encapsulation layer and including a second opening and a dummy opening; a light control pattern in the second opening; a second encapsulation layer on the partition wall and overlapping the light control pattern; and a color filter on the second encapsulation layer and overlapping the light control pattern, the second encapsulation layer includes: a first encapsulation inorganic layer on the partition wall; an encapsulation organic layer on the first encapsulation inorganic layer and including an edge overlapping the dummy opening; and a second encapsulation inorganic layer on the encapsulation organic layer.

說明書

An embodiment of the inventive concept provides a display panel DP including: a display region DA including pixels PX and a non-display region NDA adjacent to the display region DA, wherein each pixel PX includes an emission element OLED, each of the emission elements including a first electrode AE, an emission layer EML disposed on the first electrode AE, and a second electrode CE disposed on the emission layer EML; a pixel definition layer PDL including a first opening OP1 that exposes the first electrode AE of each of the emission elements OLED; a first encapsulation layer TFE1 disposed on the pixel definition layer PDL and overlapping the emission elements OLED; a partition wall BW disposed on the first encapsulation layer TFE1 and including a second opening OP2 corresponding to the first opening OP1 and a dummy opening OP-D overlapping the non-display region NDA; a light control pattern CCF-R disposed in the second opening OP2; a second encapsulation layer TFE2 disposed on the partition wall BW and overlapping the light control pattern CCF-R; and a color filter CF-R disposed on the second encapsulation layer TFE2 and overlapping the light control pattern CCF-R, wherein the second encapsulation layer TFE2 includes: a first encapsulation inorganic layer IOL10 disposed on the partition wall BW; an encapsulation organic layer OL-1 disposed on the first encapsulation inorganic layer IOL10 and including an edge overlapping the dummy opening OP-D; and a second encapsulation inorganic layer IOL20 disposed on the encapsulation organic layer OL-1.
