Problems solved by technology

Since there is only an adhesive between the liquid crystal grating and the display panel after the box is assembled, there will often be a gap between the liquid crystal grating and the display panel caused by uneven bonding pressure, shrinkage of the adhesive itself, etc. (hereinafter referred to as box thickness) unevenness and other issues, which will not only affect the display quality, reduce product yield, but also increase production costs due to repairing the above defects

Abstract

The invention provides a display device and a manufacturing method thereof. The display device comprises a display panel and a grating arranged on the light-emitting side of the display panel. The upper surface of the display panel and the lower surface of the grating are parallel to each other and are arranged adjacently. Box-thickness supporting layers are overlaid between the upper surface of the display panel and the lower surface of the grating and comprise at least one layer of support bodies. For each layer of support bodies, adhesion agents are filled in gaps between the support bodies, and the heights of the support bodies positioned at different positions are equal, so that the vertical distances from different position points on the upper surface of the display panel to the lower surface of the grating are equal. According to the display device and the manufacturing method of the display device, the space between the grating and the display device can be kept uniform, and accordingly the display quality of the display device and the product yield are improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, people are no longer satisfied with flat display, so various stereoscopic display technologies emerge as the times require. Currently, stereoscopic display technologies are mainly classified into glasses-type 3D display technologies and naked-eye 3D display technologies (ie, unassisted stereoscopic display technologies). Among them, the glasses-type 3D display technology, as the name implies, requires the audience to wear special glasses to watch the three-dimensional display effect. In practical applications, because the visual sensitivity of the glasses-type 3D display technology is poor and does not conform to conventional viewing habits, people turn their attention to the naked-eye 3D display technology more. [0003] The so...
