Liquid crystal handwriting board and manufacturing method therefor

A method for manufacturing a liquid crystal handwriting board, comprising:

• forming a first substrate provided with a first pixel electrode and a transparent electrode;
• forming a second substrate;
• aligning the first substrate with the second substrate, and forming a first liquid crystal layer between the first substrate and the second substrate;
• forming a third substrate;
• and
• aligning the first substrate with the third substrate, and forming a second liquid crystal layer between the first substrate and the third substrate;
• wherein the first substrate comprises:
• a first base, and the first pixel electrode and the transparent electrode that are disposed on a side of the first base close to the second substrate, wherein the first pixel electrode is insulated from the transparent electrode, and the first pixel electrode is closer to the second substrate than the transparent electrode is;
• wherein the first substrate, the first liquid crystal layer and the second substrate are configured to form a display portion of the liquid crystal handwriting board;
• and the first substrate, the second liquid crystal layer and the third substrate are configured to form a writing portion of the liquid crystal handwriting board;
• wherein the transparent electrode is a shield electrode, and the first substrate further comprises a second pixel electrode disposed on a side of the transparent electrode close to the first base, wherein the second pixel electrode is insulated from the transparent electrode;
• wherein a plurality of first pixel electrodes and a plurality of second pixel electrodes are provided, wherein one of the second pixel electrodes corresponds to at least one of the first pixel electrodes;
• and
• wherein an orthographic projection of the first pixel electrode on the first base is within an orthographic projection of the corresponding second pixel electrode on the first base.
