Claim:
1. An OLED pixel structure comprising a substrate plate and a plurality of sub-pixel units, each of said plurality of sub-pixel units comprising: a first electrode, an organic material functional layer and a second electrode arranged in that order on said substrate plate; and an intermediate layer arranged between said substrate plate and said first electrode; wherein, a surface of said intermediate layer away from said substrate plate has a recess of arc shape; said first electrode is located within said recess such that said first electrode, said organic material functional layer and said second electrode each has an arc shape corresponding to the arc shape of said recess; and a thin-film transistor is arranged between said substrate plate and said intermediate layer, and, said first electrode is electrically connected with a drain of said thin-film transistor, via a through hole formed, within a projection of said recess onto said substrate plate, in said intermediate layer.
