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 liquid crystal display device comprising a TFT substrate having pixels each including a common electrode formed on an organic passivation film, an interlayer insulating film formed so as to cover the common electrode, a pixel electrode having a slit and formed on the interlayer insulating film, a through-hole formed in the organic passivation film and the interlayer insulating film, and a source electrode electrically conducted to the pixel electrode via the through-hole. A taper angle at a depth of D/2 of the through-hole is equal to or more than 50 degrees. The pixel electrode covers part of a side wall of the through-hole but does not cover the remaining part of the side wall of the through-hole. This configuration facilitates the alignment film material to flow into the through-hole, thereby solving a thickness unevenness of the alignment film in vicinity of the through-hole.

Abstract: According to an embodiment, a display device includes a lower electrode, a rib including a pixel aperture, a partition including a lower portion and an upper portion, an organic layer covering the lower electrode through the pixel aperture, and an upper electrode covering the organic layer. The rib includes a taper portion which surrounds the pixel aperture and in which a thickness decreases toward the pixel aperture. The organic layer includes an end portion on the rib and a thickness deceasing portion in which a thickness decreases toward the end portion. Further, the thickness decreasing portion covers at least part of the taper portion.

Abstract: A vapor deposition method for depositing evaporated materials on a substrate using a mask includes arranging a mask frame and correcting a deflection of the mask frame in the direction of gravity after the mask frame is placed. The mask frame faces the substrate so that a first side is higher than a second side in a direction of gravity. The mask frame is provided with a mask and has the first side and the second side facing each other.
