LIQUID CRYSTAL WRITING TABLET AND PRODUCTION METHOD THEREFOR

The present disclosure provides a liquid crystal writing tablet, comprising: a first substrate and a second substrate, and a bistable liquid crystal layer located between the first substrate and the second substrate. The first substrate comprises: a first substrate base; a plurality of pixel units located on the side of the first substrate base close to the second substrate, each pixel unit comprising a thin film transistor and a pixel electrode electrically connected to a first electrode of the thin film transistor; a passivation layer, located on the side of the thin film transistors away from the first substrate base and in contact with the thin film transistors, the pixel electrodes being located between the first substrate base and the passivation layer; and a spacer, located on the side of the passivation layer away from the first substrate base and in contact with the passivation layer. Embodiments of the present disclosure further provide a production method for the liquid crystal writing tablet. La p
