Abstract

The invention discloses a self-light emitting display device. The self-light emitting display device comprises a circuit board including a driving thin-film transistor; a cathode; an organic film disposed between the circuit board and the cathode; an anode disposed between the circuit board and the organic film; and a color filter disposed between the circuit board and the anode and including a first color filter unit, a second color filter unit, and a third color filter unit; wherein the third color filter unit has a portion disposed between the first color filter unit and the second color filter unit, and wherein the third color filter unit is thicker than the first color filter unit and the second color filter unit.

Description

technical field [0001] The invention relates to a self-luminous display device. Background technique [0002] A self-luminous display device is a display device that emits light by itself. [0003] A display device is a device capable of visually displaying data. In the information society, various types of display devices capable of displaying images are increasingly required. Liquid crystal displays (LCDs) and organic light emitting diode display devices (OLEDs) have been widely used as display devices. [0004] Organic light emitting diode display devices display images using organic light emitting devices. [0005] Organic light emitting devices are self-emitting display devices that convert electrical energy into light energy using organic materials. Generally, an organic light emitting device has a structure in which an organic film is interposed between an anode and a cathode. When a driving voltage is supplied between the anode and the cathode, holes are injecte...
