Embodiment 1

[0018] Example 1: as figure 1 and image 3 , the present invention relates to a liquid crystal scattering display device, comprising a microstructure substrate (1), a microstructure electrode layer (2) corresponding to the shape of the microstructure substrate (1), and a liquid crystal spacer sublayer (3); during specific implementation, Further, an electrode layer (4) and a substrate (5) may also be included. The microstructure electrode layer (2) has a certain microstructure (21), which is a concave spherical structure in this embodiment. Under the cooperation of the electrode layer (4), an irregular electric field between the two electrode layers will be generated when electrified. The electric field acts on the liquid crystal molecules in the liquid crystal spacer layer (3) and deflects them in different directions around the microstructure, causing the liquid crystal (31) and the spacer (32) to strongly mismatch in refractive index and present a scattering state.

Abstract

The invention relates to a liquid crystal scattering display device. The liquid crystal scattering display device comprises a microstructure substrate, a microstructure electrode layer, a liquid crystal spacer layer and the like, and is characterized in that the microstructure electrode layer has a certain microstructure and can generate an irregular electric field between two electrode layers when being electrified under the cooperation of the microstructure electrode layer and the electrode layer arranged opposite to the microstructure electrode layer; the electric field acts on liquid crystal molecules in the liquid crystal spacer layer and enables the liquid crystal molecules to deflect towards different directions, so that refractive indexes of liquid crystals and spacers are strongly mismatched, and a scattering state is presented. The device is high in liquid crystal deflection driving capacity, low in required driving voltage and short in response time, is in a light passing state due to the fact that the liquid crystal is matched with the spacer refractive index under the power-off condition, and is in a scattering display state under the power-on condition, that is, no electric energy is consumed when display is not carried out, and the purpose of saving energy is achieved.
