ACTIVE MATRIX TYPE LIQUID CRYSTAL DISPLAY |
摘要 |
An active matrix type liquid crystal display device includes a substrate on which a matrix picture element electrodes reside, TFTs which are disposed in the vicinity of each picture element electrodes, and capacitor electrodes are provided, each of which is opposed to one portion of each of the picture element electrodes. A dielectric lamination structure consisting of three insulating layers is formed between the picture element electrode and the capacitor electrode. The dielectric lamination structure includes an anodic oxidation film, a gate insulating layer and a protective insulating layer. The protective insulating layer further extending over the associated TFT.
