A liquid crystal display of the chiral smectic type is caused to have grey scales, by applying a voltage of an intermediate level to the liquid crystal. Within each picture element of the display, there are a number of domains of the liquid crystal layer, some being transparent while the other being opaque rendering grey tone to the picture element.

An improved semiconductor processing is disclosed. In the manufacturing process, a semiconductor layer is formed and then undergoes photo annealing. A neutralizer is then introduced to the photoannealed semiconductor. The semiconductor thus formed demonstrates the SEL effect instead of the Staebler-Wronski effect.

Method for photo annealing non-single crystalline semiconductor films

An improved semiconductor device is disclosed which is free from current leakage due to pin-holes or other gaps. Also an improved method for provessing a semiconductor device is shown. According to the invention, gaps produced in fabricating process of the semiconductor layer are filled with insulator in advance of deposition of electrodes. By virtue of this configuration, short current paths do not result even if transparent electrode is provided on the semiconductor layer.

An improved liquid crystal filling device is shown. Prior to joining a substrate with another substrate between which the liquid crystal is to be charged, the liquid crystal is dropped on the substrate and then the other substrate is superimposed on the substrate under pressure. Sandwiched between the substrates, the liquid crystal spreads at high temperature.
