Abstract:
1. An organic electroluminescence display panel, comprising: a transistor array substrate on which a plurality of drivers is disposed, each including a thin-film transistor element; an inter-layer insulation film formed over the transistor array substrate, and having a plurality of contact holes each formed in part of respective regions of the inter-layer insulation film corresponding to the drivers; a plurality of pixel electrodes disposed on the inter-layer insulation film in correspondence with the drivers, and electrically connected to the drivers via the contact holes; an organic electroluminescence layer formed to entirely cover portions of the inter-layer insulation film where the pixel electrodes are disposed and where the pixel electrodes are not disposed; and a common electrode formed across the entirety of the organic electroluminescence layer, wherein regions of the organic electroluminescence layer corresponding to the contact holes in the inter-layer insulation film and to an area between neighbouring pixel electrodes have higher electrical resistance than an other region of the organic electroluminescence layer, the organic electroluminescence layer includes a first organic light-emitting layer and a second organic-light emitting layer arranged with separation from the first organic light-emitting layer with respect to a layering direction, a charge generation layer is located in the other region of the organic electroluminescence layer, and includes at least two sub-layers between the first organic light-emitting layer and the second organic light-emitting layer, and a mixed layer, in which material from each of the at least two sub-layers is combined, between the first organic light-emitting layer and the second organic light-emitting layer in the regions corresponding to the contact holes in the inter-layer insulation film and to the area between the neighbouring pixel electrodes.
