摘要： A liquid crystal display device is so constructed that the scattered or reflected incident rays and even the return rays are prevented from entering the transistor part. The device is free from the problem of photoelectric current leakage. The device comprises an active substrate with a pixel transistor TFT thereon and a counter substrate that faces the active substrate via liquid crystal therebetween, wherein light-shielding layers (upper light-shielding layer, and lower light-shielding layer) are formed to be adjacent to the side of the pixel transistor part that faces the counter substrate and adjacent to the side thereof that faces opposite to the counter substrate and wherein the upper light-shielding layer and the lead electrode shield the entire region except the pixel openings from the incident rays that enter the device through the counter substrate.
