Abstract: A display device includes an organic EL element layer, a liquid crystal element layer disposed on top of the organic EL element layer, and a polarizing plate disposed at a side of the liquid crystal element layer that faces an observer. The liquid crystal element layer includes two transparent substrates and a liquid crystal layer disposed between the two transparent substrates. The liquid crystal element layer is configured to be able to, by applying a voltage to the liquid crystal layer, cause a substantially quarter-wavelength retardation in light passing through the liquid crystal layer.

Abstract: In an IC mounting region in which a driver IC is to be mounted in an active matrix substrate that is used in a display device, an inspection circuit is formed together with a plurality of driving-side pads for outputting, from the driver IC, a plurality of video data signals representing an image to be displayed. The inspection circuit includes a plurality of inspection transistors connected separately to each of these driving-side pads, inspection signal lines, and an inspecting control line. The inspection signal lines and the inspecting control line are placed opposite the driving-side pads across the inspection transistors, and there are no wire intersections between the inspection transistors and the driving-side pads.

Abstract: A touch panel includes a first portion extending in a first direction within a pixel region, a source driving circuit, an inspection circuit, an input terminal region, and an inspection line extending in the first direction within a frame region. The inspection line is formed in a layer different from a layer where the first portion is formed. The inspection line is connected to the first portion and a second portion via a contact hole between a touch-detecting electrode and the source driving circuit. The second portion crosses the source driving circuit and the inspection circuit in a direction intersecting the first direction.

Abstract: A plurality of pixel electrodes are provided in a display region. A plurality of pixel transistors corresponding to the plurality of pixel electrodes in a one-to-one manner are provided in a region outside the display region. Each of the pixel transistors is connected to the corresponding pixel electrode by a pixel wiring line. An input pad group, to which a drive signal group for driving the plurality of pixel transistors is input, is provided on a TFT substrate. Here, of a region on the TFT substrate, the plurality of pixel transistors are provided only in a region other than a region between the input pad group and the display region.

Abstract: A signal obtained through sampling a gate start pulse signal GSP by using one of a plurality of gate clock signals is supplied as a shift pulse for a forward shift action (a forward shift start pulse signal) to the first stage of a plurality of stages constituting a bidirectional shift register, and a signal obtained through sampling the gate start pulse signal GSP by using another one of the plurality of gate clock signals is supplied as a shift pulse for a backward shift action (a backward shift start pulse signal) to the last stage of the plurality of stages constituting the bidirectional shift register.
