The thin film transistor substrate further includes:
a thin film transistor array (not shown) disposed on the first base plate 101;

The first spacer 50 and the second spacer 60 may have any shape, and the present invention is not limited thereto. The shapes of the first spacer 50 and the second spacer 60 fall within the protection scope of the present invention as long as the shapes can provide the supporting and buffering effects and maintain the cell thickness of the display panel.

For example, a light-transmitting region of a gray mask plate having a light transmittance of 50% to 80% is used to form the second elongated sliding grooves 40. The depth of the first and second elongated sliding grooves 30 and 40 is between 0.1 and 0.7 micrometers.
