Abstract
A writing panel includes an array substrate, a flexible substrate disposed opposite to the array substrate, a liquid crystal layer disposed between the array substrate and the flexible substrate, and a plurality of spacers each in a shape of a column disposed on a surface of the array substrate proximate to the liquid crystal layer. The array substrate includes a base and a pixel driving circuit layer disposed on the base, and the pixel driving circuit layer includes a plurality of thin film transistors and a plurality of signal lines. An orthographic projection of each spacer on the base is non-overlapping with orthographic projections of the plurality of thin film transistors and the plurality of signal lines on the base.
