Abstract

A light emitting display apparatus is disclosed, which can improve visual characteristic of a black image in accordance with reduction of diffuse reflectance while improving light emission efficiencyof light emitted from a light emitting diode. The light emitting display apparatus comprises a substrate including a plurality of pixel areas, a light emission pattern arranged in each of the plurality of pixel areas, a light emitting device layer arranged over the light emission pattern, and a selective wavelength absorbing member overlapped with at least one of the plurality of pixel areas, wherein the selective wavelength absorbing member may reduce transmittance of light of a long wavelength, which is incident.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2018-0155980 filed on December 6, 2018, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to light emitting display devices. Background technique [0004] The light-emitting display device has a high response speed, low power consumption, and unlike a liquid crystal display device, which is a self-luminous display device that does not need to use a specific light source, the light-emitting display device does not cause problems in viewing angles, and is therefore used as a next-generation flat panel display device. Having attention. [0005] A light emitting display device displays an image by emitting light from a light emitting element including a light emitting layer interposed between two electrodes. In this case, light generated by emitting light from the light emi...
