1. A matrix-type display having a plurality of pixel regions arranged in a matrix-type, comprising:
- a plurality of upper first signal lines and a plurality of lower first signal lines formed in a horizontal direction, the upper and lower first signal lines serving respectively as upper and lower boundaries of the pixel regions;
a plurality of second signal lines formed in a vertical direction between the pixel regions, the second signal lines crossing the upper and lower first signal lines and being insulated from the upper and lower first signal lines;
a plurality of auxiliary signal lines formed adjacent to the second signal lines, wherein each auxiliary signal line serves as a left or right boundary of at least one of the pixel regions, and a pair of the upper and lower first signal lines and one of the auxiliary signal lines have at least three cross points near one of the pixel regions together with one of the second signal lines;
a plurality of pixel electrodes, formed in each pixel region; and
a plurality of switching elements, each having a first terminal connected to one of the upper and the lower first signal lines, a second terminal connected to one of the pixel electrodes, and a third electrode connected to one of the second signal lines.

Abstract
A matrix-type display capable of being repaired by pixel unit, Two or more of signal lines such as scanning lines, image signal lines and auxiliary signal lines and a pixel electrode are overlapped via an insulating layer, so that a defect such as the disconnection of the image signal lines and scanning lines, the short of the pixel electrode and the signal line, and the loss of electrode of a switching element, and a pixel defect can be repaired. Here, the layout of the auxiliary gate line and dual gate line can be modified.
