Claims

[Scope of utility model registration request]

An FET in which a scanning electrode and a signal electrode that are perpendicular to each other are connected to the gate and the drain, respectively, through an insulating layer, and an amorphous silicon layer is formed between the drain and the source, and a display electrode connected to the source of the FET, In a liquid crystal matrix panel comprising a common electrode disposed opposite to the display electrode, and liquid crystal filled between the common electrode and the display electrode, the source is located in the insulating layer region where no amorphous silicon layer is present. What is claimed is: 1. A liquid crystal matrix panel driving device comprising a test electrode extending in a region where no gate exists directly below.
