Provided is an organic EL display panel offering improved luminance without increasing the current density of current flowing through organic light-emitting layers, comprising: substrate; TFT layer formed on substrate; planarizing film formed above TFT layer and having contact holes; lower electrodes arranged above planarizing film in a matrix in one-to-one correspondence with pixel units, and brought into conduction with TFT layer via contact holes; grid-shaped bank formed above planarizing film and defining openings corresponding one-to-one to lower electrodes; organic light-emitting layers formed in openings; and upper electrode formed above light-emitting layers. Each contact hole is positioned between a pair of openings adjacent in the column direction. At least one of opposing sides of any pair of openings adjacent in the column direction is reduced in width in the row direction and extends in the column direction so as to be adjacent in the row direction to the corresponding contact hole.
