Title:
MATRIX ARRAY DEVICE AND SUBSTRATE FOR MATRIX ARRAY DEVICE
Document Type and Number:
Japanese Patent JP2001013187
Kind Code:
A
Abstract:

To provide a substrate for a matrix array device and the matrix array device allowing effective and accurate inspection of variation of a transistor characteristic.

This substrate 100 for a matrix array device has inspection circuit parts 104 each disposed near an area formed with at least one of a gate line drive circuit part 102 and a signal line drive circuit part 103 over a nearly same length as one side of the drive circuit 102 or 103 or above. By measuring an oscillation frequency of the inspection circuit part 14, variety of a transistor characteristic different in each the area can be easily and accurately detected on the substrate 100 for the matrix array device.
