Patent ID: 8102336

Claim:
A display apparatus comprising: a substrate having wiring lines including at least signal lines arranged in columns, scanning lines arranged in rows, and predetermined power supply lines; and a matrix of pixels, each pixel being disposed at an intersection between a signal line and a scanning line, wherein the wiring lines are formed by patterning a conductor film; each pixel includes active devices and a light-emitting device connected to the wiring lines, operates in response to a control signal supplied from a scanning line, and causes a drive current supplied from a power supply line to flow through the light-emitting device according to a video signal supplied from a signal line; the pixel has an outer region extending linearly along a boundary with an adjacent pixel and an inner region extending along the inner side of the outer region; the wiring lines are arranged across the outer region and the inner region; an outer uneven zone is formed along the outer region and on the substrate due to level differences resulting from the presence of the wiring lines; an inner uneven zone is formed along the inner region and on the substrate also due to level differences resulting from the presence of the wiring lines; and a pattern of the conductor film of which the wiring lines are made is formed properly such that recessed portions of the outer uneven zone are located directly behind their corresponding raised portions of the inner uneven zone, as viewed from inside the pixel.
