The invention provides a method for improving the viewing angle of a liquid crystal display and a liquid crystal display. The method comprises the steps that: a black shading unit is manufactured at a position on a second surface plane of a glass substrate which is opposite to a black light resistor; and a second surface plane is over against a first surface plane, and the black light resistor and the black shading unit are respectively arranged on both sides of the glass substrate. The method for improving the viewing angle of the liquid crystal display or the liquid crystal display can improve the viewing angle of the liquid crystal display, and increase the aperture opening rate; and in addition, the invention can also improve the pair-group tolerance error of a one-fourth phase difference plate and the liquid crystal display, so that the pair-group defective rate is reduced.

The embodiment of the invention discloses an electronic device. The electronic device comprises a main body and a display screen, wherein the main body at least comprises a first surface; and the display screen comprises a first part and a second part, the second part is fixed on the first surface, and a first bending part is set between the first part and the second part; wherein, when the first part rotates relative to the second part, the first part drives the first bending part to deform, and the first bending part is set in the first surface.

A rear-focusing type zoom lens includes, in order from an object side, a positive first group being fixed, a negative second group moving toward an image plane along an optical axis during zooming from a wide-angle end to a telephoto end; a negative third group being fixed in an optical axis direction, and a positive fourth group moving along the optical axis direction to correct image plane variation being caused by zooming. The first group includes a first subgroup having a negative power as a whole and a second subgroup having a positive power as a whole. The first subgroup includes a negative meniscus lens having a convex surface directed toward the object side and a negative lens. The second subgroup includes a positive lens group having at least one positive lens, a negative lens, a positive lens, and another positive lens group having at least one positive lens.

The invention relates to the technical field of display, and discloses an optical grating, a display device and a manufacturing method of the optical grating, partition walls arranged in such a manner of corresponding to every strip-like electrodes, respectively, and liquid layers arranged between every two adjacent partition walls, wherein the optical grating comprises a first substrate and a second substrate arranged in opposition to each other; a plane electrode is arranged on one side, facing the second substrate, of the first substate; a plurality of strip-like electrodes arranged at intervals are arranged on one side, facing the first substrate, of the second substrate; the partition walls are clamped between the first substrate and the second substrate; each partition wall comprises a conductive lug boss and a hydrophilic-hydrophobic switching material layer covering the conductive lug boss; the conductive lug boss is electrically connected with the corresponding strip-like electrode; each liquid layer comprises a polar liquid and a nonpolar liquid. Due to the adoption of the technical scheme, the visual angle of the optical grating can be increased and the cost can be reduced.
