Abstract
An active matrix liquid crystal display having improved reliability. Pixel regions and a peripheral driver circuit are integrally packed on the display. TFTs forming the peripheral driver circuit are located inside a sealing material layer on the side of a liquid crystal material, thus protecting the peripheral driver circuit from external moisture and contaminants. This enhances the long-term reliability of the peripheral driver circuit. Pixel TFTs are arranged in pixel regions. The leads going from the TFTs forming the peripheral driver circuit to the pixel TFTs are shortened. This results in a reduction in the resistance. As a result, the display characteristics are improved.
