Abstract: According to one embodiment, a liquid crystal display device with an optical sensor includes a display panel and a driver IC. The display panel includes first to third signal lines, an optical sensor including a photoelectric conversion element, and a sensor signal line that is connected to the optical sensor and transmits a detection signal to the driver IC. One first wiring line drawn from one terminal of the driver IC is connected to four switching elements. Three of the four switching elements are electrically connected to one of the first to third signal lines, respectively. One of the four switching elements, different from the three switching elements, is electrically connected to the sensor signal line.

Abstract: A display device with a variant-shape display region other than the rectangular display region is configured to form a scanning line drive circuit along the variant-shape display region. The scanning line drive circuit includes bus wiring group with clock wiring for supplying clocks with three or more phases and the power supply wiring for supplying power, and the unit circuits for configuring the shift register including five or more transistors. The bus wiring and the unit circuits are formed on the different regions so as not to cross with one another.

Abstract: According to an aspect, a display device with a sensor includes: a substrate including a display region and a peripheral region on a periphery of the display region; detection electrodes arranged in a row-column configuration in the display region; and detection lines coupled to the respective detection electrodes. A shape of the substrate in a plan view includes a curve of a curved portion. The detection electrodes include a first electrode and a second electrode having a shape different from that of the first electrode in a plan view. The second electrode is juxtaposed with the curved portion. The detection lines each include a first line coupled to the first electrode and a second line coupled to the second electrode. The second line passes from the display region across the peripheral region and extends to a position overlapping with the second electrode in a plan view.

Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer and an illumination device. The first substrate includes a base, a sensor, a sensor circuit and a sensor light-shielding layer. The sensor is located between the base and the liquid crystal layer in a display area that includes pixels, and outputs a detection signal corresponding to light becoming incident from a side of the liquid crystal layer. The sensor circuit includes a switching element and is connected to the sensor. The sensor light-shielding layer is opposed to a channel area formed in a semiconductor layer included in the switching element, and blocks light from the illumination device on the channel area.
