ABSTRACT:
There is disclosed a small-sized, active matrix liquid crystal display having high reliability. The liquid crystal display comprises a TFT substrate, a counter substrate, and a layer of a liquid crystal material held between these two substrates. A plurality of pixel TFTs are arranged in rows and columns on the TFT substrate. Driver TFTs forming a driver circuit for driving the pixel TFTs are formed also on the TFT substrate. All of these TFTs are covered by the liquid crystal material directly or via a thin film to protect these TFTs. A short ring is cut after a rubbing operation and before bonding of the substrates. Therefore, during manufacturing, the TFTs are protected from static charges. Also, the cutting operation is facilitated.
