The invention discloses a light modulation device and a preparation method of the light modulation device. The light modulation device comprises a first substrate, a second substrate and a third substrate which are sequentially arranged at intervals, a first liquid crystal layer and a second liquid crystal layer, and a first circuit board, wherein the first substrate comprises a first underlayer and a first electrode layer connected with the first underlayer, the first underlayer comprises a first connecting part; the second substrate comprises a second underlayer and a second electrode layerconnected with the second underlayer, and the second electrode layer is a surface electrode; and the third substrate comprises a third underlayer and a third electrode layer connected with the third underlayer; the first liquid crystal layer is sandwiched between the first substrate and the second substrate, and the second liquid crystal layer is sandwiched between the second substrate and the third substrate; and the first circuit board is at least partially overlapped and connected with the first connecting part of the first substrate. The light modulation device provided by the invention has relatively high light transmittance and relatively small thickness, and can be stably connected with the first circuit board.
Description
Technical field [0001] The present invention relates to the field of light modulation technology, in particular to a light modulation device and a method for preparing the light modulation device. Background technique [0002] With the rapid development of light modulation devices, users have more and more requirements for light modulation devices. For example, users have higher and higher requirements for light transmittance of light modulation devices, and users also hope that light modulation devices can have a display function. [0003] Some light modulation devices include two liquid crystal cells stacked on top of each other. Usually, a connecting glue layer is arranged between the two liquid crystal cells to form the light modulation device, but the light passing through the light modulation device will be between the two liquid crystal cells. There are multiple reflections or refractions between the connecting glue layer or the air layer, causing light loss, thereby reducin...
