Abstract:
1. An organic light-emitting display panel, comprising: a thin-film transistor layer; an interlayer insulation film above the thin-film transistor layer; a first electrode plate group in a first line on the interlayer insulation film and including a plurality of first electrode plates that correspond to a first color, the first electrode plate group defining a first longitudinal edge and a second longitudinal edge that each extend along the first line; a second electrode plate group in a second line on the interlayer insulation film adjacent to the first electrode plate group and including a plurality of second electrode plates that correspond to a second color, the second electrode plate group defining a third longitudinal edge and a fourth longitudinal edge that each extend along the second line; a first bank along the first longitudinal edge of the first electrode plate group; a second bank between the second longitudinal edge of the first electrode plate group and the third longitudinal edge of the second electrode plate group; a third bank along the fourth longitudinal edge of the second electrode plate group; a first organic functional layer between the first bank and the second bank and above the first electrode plate group; a second organic functional layer between the second bank and the third bank and above the second electrode plate group; and a counter electrode covering the first organic functional layer and the second organic functional layer, wherein the interlayer insulation film includes first contact holes and second contact holes, the plurality of first electrode plates each connected with the thin-film transistor layer via one of the first contact holes, the plurality of second electrode plates each connected with the thin-film transistor layer via one of the second contact holes, each of the plurality of first electrode plates includes a first concavity shaped in conformity with a corresponding one of the first contact holes for connecting with the thin-film transistor layer, and each of the plurality of second electrode plates includes a second concavity shaped in conformity with a corresponding one of the second contact holes for connecting with the thin-film transistor layer, the interlayer insulation film includes a first thickness below the first electrode plate group that is greater than a second thickness of the interlayer insulation film below the second electrode plate group, each of the first contact holes includes a first depth that is greater than a second depth of each of the second contact holes and a first volume that is greater than a second volume of each of the second contact holes, a third volume of a first portion of the first organic functional layer above each of the plurality of first electrode plates is substantially equal to a fourth volume of a second portion of the second organic functional layer above each of the plurality of second electrode plates, and a first amount of the first organic functional layer is in the first concavity and greater than a second amount of the second organic functional layer that is in the second concavity, so that a first film thickness of the first organic functional layer in a first region other than above the first concavity in each of the plurality of first electrode plates is less than a second film thickness of the second organic functional layer in a second region other than above the second concavity in each of the plurality of second electrode plates.
