DISPLAY DEVICE
First Claim
1. A display device comprising:
- a first signal line;
a second signal line adjacent to the first signal line;
a third signal line intersecting with the first signal line and the second signal line;
a transistor including an oxide semiconductor layer; and
a pixel electrode,wherein the transistor is electrically connected to the first signal line, the third signal line and the pixel electrode,wherein the pixel electrode is overlap with portions of the first signal line and the second signal line, andwherein an overlapping area between the pixel electrode and the first signal line is substantially equal to an overlapping area between the pixel electrode and the second signal line.

Abstract
To provide a display device which can realize multi-gray scale display by reducing voltage fluctuation of a pixel, a display device includes a plurality of source signal lines, a plurality of gate signal lines which is provided so as to intersect with the source signal lines, and a pixel electrode to which a signal voltage of the source signal line is applied through a transistor including an oxide semiconductor, which is provided near an intersection portion of the source signal line and the gate signal line; in which in the pixel electrode which is provided between a pair of the adjacent source signal lines, edge portions thereof overlap with edge portions of the source signal lines and an overlapped area with one of the source signal lines is substantially equal to an overlapped area with the other source signal line.
