| 1. An active matrix type liquid crystal display comprising:
a first substrate having a common electrode formed thereon;
a second substrate opposed to said first substrate and having a plurality of pixel electrodes with high reflectance formed
thereon and having a plurality of thin film transistors corresponding to each of said pixel electrodes, wherein each pixel
electrode has a single thin film transistor of the plurality of thin film transistors; and
a liquid crystal layer disposed between said first and second substrates;
wherein each of said pixel electrodes has a smaller area than that of said common electrode, and is covered by said common
electrode;
wherein each of said pixel electrodes has a shape made of a link of a plurality of electrode portions each having approximately
symmetrical shape;
wherein said electrode portion of said pixel electrode has notches or protrusions which radially extend in a direction perpendicular
to a thickness direction of said pixel electrode from the center of said approximately symmetrical shape; and
wherein said second substrate has an area lacking an electrode, said area being adjacent to said pixel electrode, with said
area being opposite said thin film transistor across said pixel electrode.
