LIQUID CRYSTAL DISPLAY AND A DEFECT CORRECTING METHOD FOR THE SAME
First Claim
1. A liquid crystal display provided with an active matrix array substrate, the active matrix array substrate comprising:
- a plurality of gate lines and a plurality of source lines arranged on a transparent substrate so as to intersect with each other; and
a plurality of pixel electrodes arranged in a matrix, each of the pixel electrodes including;
an assembly of a plurality of sub-pixel electrodes;
separate active elements respectively connected to the sub-pixel electrodes in the vicinity of an intersection portion of the gate line and the source line; and
at least one opening portion being formed in a lower-layer side line located in a lower layer at the intersection portion of the gate line and the source line.

Abstract
A liquid crystal display uses a pixel division method by which the size of a defect can be reduced much more than conventionally possible, and a defect correcting method for the liquid crystal display. The liquid crystal display is provided with an active matrix array substrate including a plurality of gate lines and a plurality of source lines arranged on a transparent substrate so as to intersect with each other, and a plurality of pixel electrodes arranged in a matrix, each pixel electrode including an assembly of a plurality of sub-pixel electrodes, separate TFTs respectively connected to the sub-pixel electrodes in the vicinity of an intersection portion of the gate line and the source line, the TFTs being driven by the common gate line and the common source line, and at least one opening portion being formed in a lower-layer side line placed in a lower layer at the intersection portion.
