Abstract

A display device includes: a substrate; a plurality of transistors disposed on the substrate; an insulating layer disposed on the plurality of transistors; a data line and a driving voltage line disposed on the insulating layer; a pixel electrode disposed on the data line or the driving voltage line; a pixel defining layer disposed on the pixel electrode and including a pixel opening overlapping the pixel electrode; a light emitting element layer disposed in the pixel opening; and a common electrode disposed on the light emitting element layer, in which the pixel opening includes a first sub-pixel opening and a second sub-pixel opening, and a first blocking portion disposed between the first sub-pixel opening and the second sub-pixel opening.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2020-0117035 filed in the Korean Intellectual Property Office on September 11, 2020, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to display devices. Background technique [0004] Among various types of display devices, liquid crystal display (LCD) devices, plasma display panel (PDP) display devices, organic light emitting diode (OLED) display devices, field effect display (FED) devices, and electrophoretic display devices are well known and widely used use. [0005] Compared with LCD devices that require a separate light source, OLED display devices have reduced thickness and light weight due to self-luminous properties. In addition, OLED display devices have high-level characteristics such as low power consumption and high brightness. [000...
