摘要

A display device includes: a substrate; signal lines including a gate line, a data line, and a driving voltage line that collectively define an outer boundary of a pixel area; a transistor connected to the signal line; a first electrode extending across the pixel area and formed on the signal line and the transistor, and connected to the transistor, the first electrode having a first portion overlying only the signal line and the transistor, and a second portion including all of the first electrode not included in the first portion; a pixel defining layer formed on only the first portion of the first electrode; an organic emission layer formed on substantially the entire second portion but not on the first portion; and a second electrode formed on the pixel defining layer and the organic emission layer.

說明書

The first drain electrode 177a faces the first source electrode 176a, and the first drain electrode 177a is connected with the first drain region 1357a through the first drain contact hole 167a. Similarly, the second drain electrode 177b faces the second source electrode 176b, and the second drain electrode 177b is connected with the second drain region 1357b through the second drain contact hole 167b.

The first drain electrode 177a is extended along, or generally parallel to, the gate line and electrically connected with the second gate electrode 154b through the first contact hole 81.

The third capacitor electrode 178 protrudes from the driving voltage line 172 and overlaps the second capacitor electrode 158.
