1. A display device comprising:
- a pixel array comprising pixels having x rows and y columns (x and y are natural numbers);
a first driver circuit comprising a first write control circuit and connected to x signal lines along a first direction; and
a second driver circuit comprising a second write control circuit and connected to y signal lines along a second direction,wherein first signals and second signals for displaying an image by pixels having m (m<
x) rows and n columns (n<
y) selected from the pixels having x rows and y columns are inputted to the first driver circuit and the second driver circuit, andwherein the first driver circuit inputs the first signals to (p+1)-th to (p+m)-th (p<
x) signal lines along the first direction and the second driver circuit inputs the second signals to (q+1)-th to (q+n)-th (q<
y) signal lines along the second direction in accordance with EN signals inputted to the first write control circuit and the second write control circuit.

Abstract
In a display device of the active matrix type, write control circuits as provided in a source side driver circuit and a gate line side driver circuit are operable to selectively supply output signals of shift registers to a source line and a gate line. Whereby, it becomes possible to render the non-display section of an image clearer or visually distinguishable, which in turn leads to capability of successful execution of images with excellent quality.
