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.
