Abstract

The invention provides an optical film layer and a display device. The optical film layer includes a first electrode layer, a second electrode layer, a first liquid crystal layer, a second liquid crystal layer and a filling layer. Both the first liquid crystal layer and the second liquid crystal layer are disposed on a side of the first electrode layer facing the second electrode layer. Taking the side of the first electrode layer facing the filling layer as a reference plane, the height of the second liquid crystal layer is smaller than the height of the first liquid crystal layer.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to an optical film layer and a display device. Background technique [0002] In recent years, with the continuous advancement of display technology, viewers have higher and higher requirements on the display quality (such as image resolution, color saturation, etc.) of the display. However, with the improvement of display resolution, the more detailed the display picture, the smaller the pixel size, and the worse the brightness performance of the large viewing angle. For ultra-high-definition displays, it is urgent to solve this technical problem. [0003] In the prior art, the light at the front viewing angle is modulated to a large viewing angle by combining an optical film layer structure to increase the display brightness at a large viewing angle. Although this technology can improve the brightness of the bright state display when viewed at a large viewing angle, it will also a...
