发明名称 Liquid crystal display device
摘要 A liquid crystal display device sandwiching liquid crystal between a TFT substrate having a rectangular plane and an opposing substrate having a rectangular plane, wherein a long side of the TFT substrate is longer than a long side of the opposing substrate, the long side of the opposing substrate is formed with a chamfer, and a light shielding film made of metal is formed on the TFT substrate around a position corresponding to the center of the long side of the opposing substrate. By using the light shielding film, the chipping condition of the opposing substrate near the chamfer can be accurately and rapidly evaluated.

主权项 1. A liquid crystal display device sandwiching liquid crystal between a TFT substrate having a rectangular plane with a TFT and a pixel electrode formed thereon in a matrix form and an opposing substrate having a rectangular plane with a color filter formed thereon, wherein a long side of the TFT substrate is longer than a long side of the opposing substrate, the long side of the opposing substrate is chamfered, and the TFT substrate has a light shielding film made of metal formed thereon around a position corresponding to the center of the long side of the opposing substrate, wherein in a portion of the opposing substrate corresponding to the light shielding film of the TFT substrate, a size of the light shielding film is between 1.3 mm and 2.6 mm along the long side of the opposing substrate and between 0.1 mm and 0.2 mm along a short side direction of the opposing substrate, and there is no chip on a top surface of the opposing substrate in a portion formed with the chamfer.
