An image pickup element includes a pixel matrix, a pupil dividing portion, and a shielding portion. Pixels in the pixel matrix include a photoelectric conversion portion, and are arranged in units of a matrix of a predetermined number of the pixels. The pupil dividing portion is arranged on a side of a light receiving surface of the photoelectric conversion portion of each pixel to divide a pupil region.

Abstract:
The present disclosure relates to the field of liquid crystal display technologies, and discloses a color filter substrate and a display component. For a display component which takes a transverse electric field as a driving electric field, when a part of a black matrix of a color filter substrate is located at a non-display region, the black matrix includes a portion to be connected, and a predetermined voltage is applied to the black matrix through the portion to be connected, so as to ensure that a voltage difference between the black matrix and a pixel electrode or between the black matrix and a common electrode is small enough to be unable to drive liquid crystal molecules to deflect, thereby avoiding undesirable phenomenon such as becoming green when displaying in dark state, and improving production yield and display quality.
Abstract:
Provided are a color filter capable of improving an aperture ratio of a BM, a liquid crystal display apparatus, and a method of manufacturing the color filter. For an R layer disposed in an opening, a right exposure part and a left exposure part of a G layer disposed in an opening adjacent to a right side of the opening are patterned by exposing using an alignment mark. Briefly, portions of the RGB layers facing each other in a horizontal direction, which are respectively to be disposed in two openings adjacent to each other in the horizontal direction, may be patterned by exposing using the same alignment mark. As a result, unnecessarily close arrangement or separated arrangement of the RGB layers caused by referring to the different alignment marks does not occur. Consequently, there is no need to increase a BM between the RGB layers in the horizontal direction. Therefore, an aperture ratio of the BM is improved.
