Detailed Description

In order to make the purpose, technical solution and effect of the present invention clearer and more clear, it is clear that the following list examples are to the present invention for further detailed description. It should be noted that the embodiments described herein are only for explaining the present invention and are not used to limit the present invention.

As shown in figures 1-6, the utility model discloses the structure is preceding polaroid 1, preceding ITO glass 2, preceding PI layer 3, liquid crystal layer 4, back PI layer 5, back ITO glass 6, back polaroid 8 and sealed glue 8 all around. The specific structural position relationship is as follows: a front ITO glass 2 and a front PI layer 3 are sequentially arranged below the front polaroid 1; the rear ITO glass 6 and the rear PI layer 5 are sequentially arranged on the rear polarizing plate 7; a peripheral sealant 8 is arranged between the front ITO glass 2 and the rear ITO glass 6 for sealing, and a space formed among the front ITO glass 2, the rear ITO glass 6 and the peripheral sealant 8 is a liquid crystal layer 4; the inner surface layers of the front PI layer 3 and the back PI layer 5 are set as PI inner surface layers 9; the PI inner surface layer 9 is provided with grooves 10, the left side surface and the right side surface of each groove 10 are in the same direction, or the left side surface and the right side surface of each groove 10 are in two opposite directions.
