Abstract
An array substrate of a TFT-LCD includes a transparent substrate, a buffer layer, an active-matrix drive circuitry, a passivation layer, and a pixel electrode. The buffer layer is formed on the transparent substrate and includes a first buffer section and a second buffer section in each pixel region. The first buffer section is over-etched and thus has a thickness smaller than that of the second buffer section. The active-matrix drive circuitry is provided on each second buffer section for addressing a pixel of the TFT LCD, and the passivation layer having at least one contact hole in each pixel region is formed overlying the active-matrix drive circuitry. The pixel electrode is formed on each first buffer section and connected to the active-matrix drive circuitry through the contact hole.
