Abstract: The present invention has been made to improve the anti-reflection effect of a light shielding film on the upper surface of a through-hole and provide improved image quality. Disclosed is a liquid crystal display device including a TFT substrate and a counter substrate. The TFT substrate is configured such that a pixel electrode and a common electrode are formed on an organic passivation film, and that a through-hole for connecting the pixel electrode to a TFT is formed in the organic passivation film. A capacitor insulating film is formed between the common electrode and the pixel electrode. A light shielding film is formed and layered on the common electrode. The through-hole is filled with resin. At the upper surface of the through-hole, the capacitor insulating film is formed on the resin. The light shielding film and the common electrode are formed on the capacitor insulating film.

Abstract: A liquid crystal display device includes a first substrate, a second substrate and liquid crystal. The first substrate includes pixel electrodes, a peripheral circuit and a dummy wiring. The peripheral circuit and the dummy wiring are provided outside a pixel area in which the pixel electrodes are arranged. The second substrate is opposed to the first substrate through the liquid crystal. The second substrate includes a translucent conductive film that is provided on an opposite side of the second substrate to a side where the liquid crystal is present. The dummy wiring is located on an outer peripheral side of the substrates than the peripheral circuit and is provided independently of the peripheral circuit in terms of circuit. The dummy wiring is grounded outside the first substrate.

Abstract: A detection device includes: a substrate having a sensor region in which photosensors are arranged in a first direction and a second direction. In the sensor region, the substrate includes: read control scan lines extending in the first direction and configured to transmit read control signals; and output signal lines extending in the second direction. The photosensors includes: dummy elements comprising first photodiodes and arranged along a contour of the sensor region; and detection elements comprising second photodiodes and arranged on an inner side of a dummy region in which the dummy elements are arranged. The dummy elements are coupled to neither the read control scan lines nor the output signal lines. The detection elements are coupled to the read control scan lines and the output signal lines and are configured to, after receiving the read control signals, output signals generated by the first photodiodes to the output signal lines.
