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 17):
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 to cover 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 to which 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; forming a third material layer by deposition on the display substrate on which the flat portion has been formed; coating a third photoresist layer which covers the third material layer, and performing a third exposure and development, to form a pattern comprising the third functional film on the third photoresist layer at a position to which the flat portion corresponds; etching the display substrate on which the third exposure and development has been performed, to form the third functional film, and lifting off the third photoresist layer, wherein the third functional film covers the flat portion; coating a fourth photoresist layer which covers the third functional film, and performing a fourth exposure and development, to form a pattern comprising via holes on the fourth photoresist layer; etching the display substrate on which the fourth exposure and development has been performed, to form the via holes on the third functional film; forming a second material layer on the display substrate on which the via holes have been formed, the second material layer is connected with the flat portion through the via holes; coating a fifth photoresist layer which covers the second material layer, and performing a fifth exposure and development, to retain photoresist on the fifth photoresist layer to which the protrusion portions correspond; and etching the display substrate on which the fifth exposure and development has been performed, to form the protrusion portions on the second material layer, and lifting off the fourth photoresist layer and the fifth photoresist layer, to form a second functional film which comprises the flat portion and the protrusion portions on the flat portion.
