摘要： The displacement between a TFT substrate and a counter substrate and the cut of an alignment film caused by a columnar spacer are prevented. A liquid crystal display device includes: a TFT substrate including a scanning line extending in a first direction, a picture signal line extending in a second direction, a pixel electrode formed in a region surrounded by the scanning line and the picture signal line, and a common electrode formed as opposed to the pixel electrode through an insulating film; a counter substrate disposed as opposed to the TFT substrate and having a spacer; and a liquid crystal sandwiched between the substrates. A common metal interconnection is formed to cover the picture signal line or the scanning line, and stacked on the common electrode. A through hole is formed on the common metal interconnection. The tip end of the spacer is disposed inside the through hole.

摘要： To provide a thin liquid crystal display device featuring excellent color reproducibility. The liquid crystal display panel includes: a liquid crystal display panel outputting different colors on a per-pixel basis; and a backlight. The backlight includes: a light source; a light guide; a reflective sheet on a back side of the light guide; and a group of optical sheets including a wavelength converter and disposed between the liquid crystal display panel and the light guide. The wavelength converter has a structure where quantum dots are dispersed in a transparent medium. The wavelength converter is bonded to another optical medium by means of a diffusing adhesive. Nanoparticles for developing Rayleigh scattering are dispersed in the wavelength converter.

摘要： 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.

摘要： A thin-film transistor includes a gate electrode made of metal, a light transmissive gate insulating film that covers the gate electrode, a semiconductor film that overlaps with the gate electrode through the gate insulating film, and a source electrode and a drain electrode, made of metal, and spaced from each other. The gate electrode and the semiconductor film have respective through-holes communicated with each other so that the gate insulating film enters an inside of the through-holes. The gate insulating film has an area of the inside of the through-holes of the gate electrode and the semiconductor film. The source electrode and the drain electrode pass through the inside of the through-holes of the gate electrode and the semiconductor film so as to overlap with a part of the area of the inside of the through-hole of the gate insulating film and avoid a remaining portion thereof.

摘要： In a plan view, a spacer member is arranged at a position overlapping with a first line portion of a second pixel electrode. The second pixel electrode has a second connecting portion that connects the first line portion and the second line portion arranged next to the first line portion. The second connecting portion of the pixel electrode is arranged between a region where the first line portion of the second pixel electrode overlaps with the spacer member and one end portion of the first line portion of the second pixel electrode.
