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.

In more detail, with the organic emission layer 370 does not overlap the pixel defining layer 195. Thus, the organic emission layer 370 covers the entire pixel area except for the gate line 121, the data line 171, the driving voltage line 172, the first gate electrode 154a, the second gate electrode 154b, the first source electrode 176a and the first drain electrode 177a, the second source electrode 176b and the second drain electrode 177b, and the like, i.e. except for the opaque layers.

Next, as illustrated in FIGS. 3 and 4, a second electrode 270 is formed on the pixel defining layer 195 and the organic emission layer 370.
