Abstract
A light emitting display panel includes a plurality of pixels. Each of the plurality of pixels includes: a first pixel circuit layer including a first pixel circuit constituting a pixel driving circuit; a second pixel circuit layer arranged on the first pixel circuit layer, wherein the second pixel circuit layer comprises a second pixel circuit forming the pixel driving circuit; a third pixel circuit layer arranged on the second pixel circuit layer, wherein the third pixel circuit layer comprises a third pixel circuit forming the pixel driving circuit; a fourth pixel circuit layer arranged on the third pixel circuit layer, wherein the fourth pixel circuit layer comprises a fourth pixel circuit forming the pixel driving circuit; and a light emitting device layer disposed on the fourth pixel circuit layer, the light emitting device layer including a light emitting device electrically connected to the fourth pixel circuit.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0144210 filed on November 12, 2019, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to a light emitting display panel. Background technique [0004] Since the light emitting display device displays an image by using a self-luminous device, the light emitting display device has a fast response time, low power consumption, and a good viewing angle, and thus is attracting more attention as a next-generation device. [0005] Each of a plurality of pixels constituting a light emitting display panel of a light emitting display device includes a pixel driving circuit. The pixel driving circuit controls the level of current flowing from the driving power source to the light emitting device based on the switching of the driving transistor based on the data voltage, thereby...
