Abstract
A pixel electrode and a thin film transistor connected to the electrode are provided above one substrate. A shading film is provided above another substrate. The shading film has an overhanging portion defining a corner cutting in an opening area of each pixel in the crossing area where the data line and the scan line cross with each other. A channel region of the thin film transistor is arranged in the crossing areas. Thus, light resistance is enhanced and a high-grade image is displayed in an electro-optical apparatus.
Claims16
An electro-optical apparatus, comprising:
- a pair of first and second substrates;
- an electro-optical material sandwiched between the pair of first and second substrates;
- a pixel electrode formed above the first substrate;
- a thin film transistor to switch and control the pixel electrode;
- a data line to supply an image signal to the thin film transistor;
- a scan line which supplies a scan signal to the thin film transistor and crosses with the data line;
- and
- a first shading film covering at least a channel region of a semiconductor layer forming the thin film transistor from an upside, the first shading film being formed above the second substrate, the first shading film having an overhanging portion overhanging such that the portion defines a corner cutting in an opening area of each pixel corresponding to the pixel electrode in a crossing area where the data line and the scan line cross with each other as viewed two-dimensionally, the channel region being arranged within the crossing area.
