1. A display system adapted to be mounted on a head of an operator, said system comprising:
- a pair of flat panel displays for right and left eyes, each of the flat panel displays comprising an active matrix display;
a first plurality of wirings and a second plurality of wirings, in the active matrix display, forming a lattice;
a plurality of pixels in the active matrix display, said plurality of pixels surrounded by said first and said second plurality of wirings;
a plurality of thin film transistors, each transistor formed at an intersection of each of said first and said second plurality of wirings,wherein a horizontal dimension of said pixels of each of the flat panel displays is continuously or gradually varied by changing lengths of said first plurality of wirings according to a horizontal angle of view from a predetermined position.

Abstract
With a head mount display, a difference in an effective area of pixels depending on a horizontal angle of view is corrected. In an active matrix region 106, a horizontal width e of a pixel electrode in a region where the horizontal angle of view becomes large is set to be larger than a horizontal width d of pixels in a region where the horizontal angle of view becomes small. With this arrangement, a difference in a visual area of the pixel electrode caused by the horizontal angle of view can be corrected.
