US 2020/0091261 A1 · DISPLAY DEVICE INCLUDING A PASSIVATION LAYER HAVING AN UNEVEN SURFACE

Abstract

A display device includes a substrate, a transistor, a pad portion, a passivation layer, and a pixel definition layer. The substrate includes a display area and a peripheral area disposed at an edge of the display area. The transistor is disposed on the display area. The pad portion is disposed on the peripheral area. The passivation layer is disposed on the transistor. The pixel definition layer is disposed on the passivation layer. A portion of the passivation layer extends to the peripheral area. An upper surface of the portion of the passivation layer disposed on the display area is substantially flat. An upper surface of the portion of passivation layer disposed at the peripheral area has an uneven structure. The uneven structure includes a recess portion and a convex portion. The pixel definition layer covers the portion of the passivation layer disposed on the peripheral area.
