Liquid crystal display device

Abstract

The purpose of the present invention is to realize a structure that the testing terminals are remained in the final product in the liquid crystal display device having a variant display area. The structure of the present invention is as follows. The display area is variant, the outer shapes of the counter substrate 200 and the TFT substrate are also variant similar to the display area. The terminal area formed on the TFT substrate has a straight first area, a second area and a third area; the second area and the third are bent from the first area and formed at sides of the first area. A plurality of terminals to drive the liquid crystal display device exist in the first area, and a plurality of terminals for testing the liquid crystal display device exist in the second area and the third area.
