Abstract:
A display substrate, a method for fabricating the same, and a display apparatus are disclosed. The display substrate is provided with functional films, at least one of the functional films includes a protrusion array on a side away from the display substrate. When the display substrate is assembled with another display substrate, protrusion portions of the protrusion array are embedded into a frame sealant between the display substrate and the another display substrate.

Claim (Index 19):
The method of  claim 15 , wherein the step of forming the protrusion array on the side of at least one of the functional films away from the display substrate comprises:\n forming a first functional film; forming a first material layer by deposition on the display substrate on which the first functional film has been formed; coating a second photoresist layer which covers the first material layer, and performing a second exposure and development, to form a pattern comprising the flat portion on the second photoresist layer at a position the non-recessed regions of the first functional film correspond; etching the display substrate on which the second exposure and development has been performed, to form the flat portion on the first material layer, and lifting off the second photoresist layer; coating a third photoresist layer which covers the flat portion, and performing a third exposure and development, to form a pattern comprising via holes on the third photoresist layer at a position the protrusion portions of the flat portion corresponds; depositing on the display substrate on which the third exposure and development has been performed, to form a second material layer on the third photoresist layer, wherein the second material layer is connected with the flat portion through the via holes; coating a fourth photoresist layer which covers the second material layer, and performing a fourth exposure and development, to retain the photoresist on the fourth photoresist layer to which the protrusion portions correspond; etching the display substrate on which the fourth exposure and development has been performed, to form the protrusion portions on the second material layer, and lifting off the third photoresist layer and the fourth photoresist layer, to form a second functional film which comprises the flat portion and the protrusion portions on the flat portion; depositing on the display substrate on which the fourth exposure and development has been performed, to form a third material layer which covers the second functional film; coating a fifth photoresist layer which covers the third material layer, and performing a fifth exposure and development, to form a pattern comprising the third functional film on the fifth photoresist layer; and etching the display substrate on which the fifth exposure and development has been performed, to form the third functional film on the third material layer, and lifting off the fifth photoresist layer.
