Abstract

Official abstract text for this publication.

A self-light emitting display unit capable of improving manufacturing yield is provided. Sizes of color pixel circuits corresponding to pixels for R, G, and B are respectively set unevenly within a pixel circuit according to a magnitude ratio of drive currents which allow color self-light emitting elements in the pixel to emit with a same light emission luminance. Thereby, the pattern densities of color pixel circuits respectively corresponding to the pixels for R, G, and B become even to each other, and the pattern defect rate as the whole pixel circuit is decreased.

First claim

Opening claim text (preview).

What is claimed is: 1. An organic EL display device comprising: a pixel layer including a first color pixel and a second color pixel; and a pixel circuit layer including a first color pixel circuit and a second color pixel circuit adjacent to the first color pixel circuit, wherein the first color pixel has a first anode electrode, the second color pixel has a second anode electrode, the first color pixel circuit includes a first drive transistor configured to flow a drive…
