Abstract
The present invention provides a mask plate, a method for processing an organic layer and a method for fabricating an organic light-emitting diode display substrate. The mask plate comprises a light transmitting region and a light shading region. The light transmitting region corresponds to a region of an organic layer to be removed. The light transmitting region is provided with a photothermal conversion material for converting light energy into heat energy. The light shading region is provided with a light blocking layer for blocking transmission of light. The mask plate is suitable for processing an organic layer and particularly suitable for forming an auxiliary via hole in an organic light-emitting layer of an organic light-emitting diode display substrate.
