Abstract

An organic light emitting diode display device includes a substrate having first, second, third and fourth subpixels; first, second and third color filter layers in the second, third and fourth subpixels, respectively, on the substrate; a first wavelength converting layer in the first subpixel on the substrate and second and third wavelength converting layers on the first and second color filter layers, respectively; and a light emitting diode in each of the first, second, third and fourth subpixels over the first, second and third wavelength converting layers.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2019-0160623 filed in Korea on December 5, 2019, which is hereby incorporated by reference in its entirety for all purposes as if fully set forth herein Same. technical field [0003] The present invention relates to an organic light emitting diode display device, and more particularly, to an organic light emitting diode display device including a wavelength conversion layer. Background technique [0004] Recently, flat panel displays (FPDs) having a thin profile, light weight, and low power consumption have been developed and applied to various fields. [0005] In an organic light-emitting diode (OLED) display device in a flat-panel display, charges are injected into the light-emitting layer between the cathode of the electron-injecting electrode and the anode of the hole-injecting electrode to form excitons, and the excitons are tran...
