ABSTRACT:
On a TFT array substrate, an electrooptic device contains pixel electrodes disposed in an image display region, TFTs which are disposed in a peripheral region at the periphery of the image display region and which form a peripheral circuit, and a protective film formed so as to cover at least a part of the peripheral region. The protective film is not provided in at least a part of an opening region of each pixel formed in the image display region. Accordingly, in the electrooptic device, such as a liquid crystal device, while the device life is increased by protecting electronic elements, such as transistors formed on the substrate by the protective film, degradation of display image quality caused by the presence of the protective film is reduced or prevented.
