Description

Liquid crystal display device, liquid crystal panel structure and optical lens structure thereof

The present invention relates to an optical structure, and more particularly to an optical lens structure that utilizes an inorganic insulating layer to isolate the action of an organic solvent between an alignment layer and an isotropic layer.

With the development of technology, liquid crystal displays (LCDs) with small size, power saving, flat right angle, low power consumption and low radiation have gradually replaced the traditional cathode tube display (CRT). . The importance of liquid crystal displays in daily life is also becoming more and more significant. For example, mobile phones, notebook computers, digital cameras, and satellite navigation systems, such as mobile phones, notebook computers, digital cameras, and satellite navigation systems, use liquid crystal displays as their information display.

At present, liquid crystal displays are still dominated by flat-panel liquid crystal displays. However, with the strong demand for stereoscopic sound and light effects, stereoscopic liquid crystal displays have gradually begun to be valued in the market.

Liquid crystal displays are based on liquid crystal molecules in which liquid crystal molecules are sandwiched between two sheets of glass sheets subjected to alignment treatment. The intermediate liquid crystal molecule between the solid state and the liquid state not only has the property that the liquid is easy to flow by the external force, but also has the optical heterogeneous nature characteristic of the crystal. So when the liquid crystal molecules are driven by an electric field, the liquid crystal molecules The alignment state can be changed to other orientations, thereby causing a change in optical characteristics of light that penetrates the liquid crystal molecules. Using the above techniques, conventional techniques can be used to fabricate various types of liquid crystal displays, such as Twisted Nematic Liquid Crystal Display (TN LCD), Thin Film Transistor Liquid Crystal Display (TFT). -LCD) and so on.
