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 display device includes a display panel, a linearly polarizing plate, and a first polarized light-selective reflector disposed sequentially toward a viewer; a first phase difference plate and a first lens disposed closer to the viewer relative to the first polarized light-selective reflector and facing each other; a semi-transparent mirror disposed closer to the viewer relative to the first phase difference plate and the first lens; a second lens and a second phase difference plate disposed closer to the viewer relative to the semi-transparent mirror and facing each other; and a second polarized light-selective reflector disposed closer to the viewer relative to the second lens and the second phase difference plate. The first lens and the second lens have shapes asymmetric about the semi-transparent mirror as a plane of symmetry in a cross-sectional view in a direction from the display panel toward the second polarized light-selective reflector.

Abstract: A display device with a touch panel starts a first touch detection process within an extension period, and ends the first touch detection process before a normal drive period starts. The display device with a touch panel performs a process of outputting first report data when a length of the extension period is equal to or longer than a predetermined length. The display device with a touch panel performs, after the normal drive period starts, a second touch detection process, a writing process, and a process of outputting second report data.
