Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent leakage from being caused between adjacent pixel electrodes by a light shield film without making the manufacturing process complicated by providing the light shield film as a layer below an inter-layer insulating film. SOLUTION: A source signal line 8 is formed as a single layer and the light shield film 11 is formed blow the inter-layer insulating film 12 while covering the source signal line 8 and the channel region 21 of the amorphous Si layer 5 of a TFT 15 and also patterned in the same shape with a channel protection film 10.
