Abstract
The present invention provides a technique for reducing pixel brightness unevenness in a case where driving circuits for switching gate lines to a selected or non-selected state are provided in pixels. An active matrix substrate includes, in each pixel PIX, a pixel-switching elementand a pixel electrode PXB. Further, in the active matrix substrate, a plurality of driving circuits that switch one gate line to a selected or non-selected state are arranged in the pixels, and control linesthat supply control signals to the driving circuits are arranged in the pixels. Each driving circuit includes a plurality of switching elements and an internal line netA. At least a part of the driving circuit lines among the control linesconnected to the driving circuit, and the internal line netA in the driving circuits, are arranged in the vicinity of the pixel-switching element, and potentials thereof do not change at a timing when the gate lineconnected with the pixel-switching elementshifts to the non-selected state.
