Abstract
The invention miniaturizes a liquid crystal panel and thus provides a lightweight panel. A TFT provided so as to correspond to intersections of data lines and scanning lines. A dummy pixel area does not contribute to image display, while an effective pixel area contributes to image display. An identification pattern represents a sequence of scanning lines. By forming the identification pattern in the dummy pixel area, the data lines and a scanning line driving circuit can be provided closer to each other, and a picture frame area can be reduced.
Claims11
An electro-optical panel, comprising:
- a plurality of scanning lines;
- a plurality of data lines;
- switching elements disposed in a matrix form so as to correspond to intersections of the scanning lines and the data lines, respective pixel areas, partitioned by the respective scanning lines and the respective data lines, having an effective pixel area that contributes to image display and a dummy pixel area that does not contribute to image display;
- and
- an identification pattern, at least a part of the identification pattern representing identification information to identify the respective scanning lines being formed in the dummy pixel area.
