1. An organic EL display panel comprising:
a substrate; a plurality of pixel electrodes arranged in rows and columns over the substrate; an insulating film elongated in a row direction over the pixel electrodes, the insulating film having a portion recessed to coat edges of pixel electrodes adjacent in a column direction, the edges facing each other in the column direction; a plurality of banks each elongated in the column direction over a region corresponding to a gap between pixel electrodes adjacent in the row direction; a hole transport layer disposed above the pixel electrodes, and entirely above an upper surface of the insulating film in a gap between the banks; an organic light-emitting layer disposed over the hole transport layer in the gap between the banks; and a common electrode disposed over the organic light-emitting layer, wherein a dielectric constant of the insulating film is at least 3.8, the insulating film measures at least 10nm and at most 75nm in the thickness, a hole mobility of the hole transport layer is at least 103 times and at most 105 times a hole mobility of the organic light-emitting layer, and light is emitted from a first light-emitting portion and a second light-emitting portion of the light-emitting layer, the first light-emitting portion being above the pixel electrodes excluding where the insulating film is disposed, and the second light-emitting portion, with respect to a vertical direction, being above and vertically aligned with both the pixel electrodes and the insulating film, and wherein a cross-sectional shape of each of the light emitting layer, the pixel electrodes, and the hole transport layer conforms to and to and extends across a width of a cross-sectional shape of a contact hole formed in an interlayer insulating film of the substrate so as to define a cavity above the contact hole. |
