The light guide portion includes a plurality of light guide paths provided throughout from the one surface to the other surface of the light guide portion, and a light-absorbing portion having higher absorbance of the light than that of the light guide paths. When viewed from a direction in which the light-receiving elements and the light guide portion are stacked, more than one of the light guide paths overlap one of the light-receiving elements.

According to one embodiment, an alignment processing device includes a light source, a polarizing beam splitter, a first optical system, a second optical system, a first retardation film, a second retardation film, a moving mechanism configured to move a processing substrate in which a thin film is formed, and a controller. Interfering light is formed in an exposure area by first circularly polarized light and second circularly polarized light. The controller performs control so as to repeat a process of exposing part of an area of the thin film by the interfering light and a process of moving the processing substrate.

Alignment processing device and manufacturing method of liquid crystal optical element

In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

Display device

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.
