Array substrate and fabricating method thereof, reflective display panel, and display device

A display device comprising a reflective display panel, the reflective display panel comprising:

• an array substrate, a cell substrate, and a liquid crystal layer between the array substrate and the cell substrate, wherein the array substrate comprises:
• a base having a plurality of pixel electrodes, a plurality of gate lines, a plurality of data lines, and a plurality of thin film transistors disposed thereon, wherein the data lines and the gate lines are alternately arranged to provide a plurality of pixel units, and both the pixel electrodes and the thin film transistors are in a one-to-one correspondence with the pixel units;
• an insulating layer disposed between the pixel electrodes and a layer where a data pattern is located, wherein the data pattern comprises the data lines and source electrodes of the thin film transistors, the pixel electrodes overlap with a portion of the data pattern, the pixel electrodes are connected to drain electrodes of the thin film transistors through via holes, and the pixel electrodes overlap at least part of each of the data lines and overlap the drain electrodes and the source electrodes;
• a plurality of recesses disposed on the insulating layer, wherein an orthographic projection of one of the recesses on the base is outside of an orthographic projection of an overlapping region of one of the pixel electrodes and the data pattern on the base;
• and
• wherein a row spacing region exists between every two adjacent rows of pixel electrodes, a cross region of the row spacing region and the column spacing region is a spacer region, and an orthographic projection of the spacer region does not overlap with orthographic projections of the data lines and the gate lines.
