Abstract:
1. An organic electroluminescence display panel, comprising: a substrate; a thin-film transistor layer above the substrate; a planarizing film above the thin-film transistor layer; an electrode layer above the planarizing film; a plurality of contact holes in the planarizing film via which a wire is disposed such that the thin-film transistor layer is in electrical contact with the electrode layer; and a bank having repellency on at least one surface, the bank being above the electrode layer and having depressions and defining vacancies, each of the depressions being defined by an area of an upper surface of the bank being recessed from surrounding areas of the upper surface, each of the vacancies extending through the bank from the upper surface of the bank to a lower surface of the bank and arranged in rows and columns to define regions for forming organic electroluminescence elements, wherein: each of the depressions is located above a corresponding one of the contact holes, each of the vacancies is not located above any of the contact holes and does not overlap with any of the depressions, a light-emitting layer is within the vacancies, a layer including a same organic material as an organic material included in the light-emitting layer is within the depressions, and the upper surface of the bank, at bottoms of the depressions, is below a lower surface of the light-emitting layer.
