ORGANIC EL DISPLAY PANEL AND ORGANIC EL DISPLAY DEVICE

摘要

Pixels include red sub-pixels, green sub-pixels, first blue sub-pixels that emit dark blue light, and second blue sub-pixels that emit light blue light. Above a substrate, first blue pixel electrodes and first blue organic light-emitting layers are layered in regions of the first blue sub-pixels and second blue pixel electrodes and second blue organic light-emitting layers are layered in regions of the second blue sub-pixels. The first blue light-emitting layers and the second blue light-emitting layers are made from the same material. In a direction perpendicular to a top plane of the substrate, a distance between top surfaces of the first blue organic light-emitting layers and top surfaces of the first blue pixel electrodes is less than a distance between top surfaces of the second blue organic light-emitting layers and the surfaces of the second blue pixel electrodes.

1. An organic electroluminescence (EL) display panel in which a plurality of pixels are arranged in a matrix of rows and columns on a substrate, each pixel including a red sub-pixel that emits red light, a green sub-pixel that emits green light, a first blue sub-pixel that emits dark blue light, and a second blue sub-pixel that emits light blue light, the organic EL display panel comprising:
the substrate; a first blue pixel electrode and a first blue organic light-emitting layer layered above the substrate in a region of the first blue sub-pixel; and a second blue pixel electrode and a second blue organic light-emitting layer layered above the substrate in a region of the second blue sub-pixel, wherein the first blue organic light-emitting layer and the second blue organic light-emitting layer are made from the same material, and in a direction perpendicular to a top plane of the substrate, a distance between a top surface of the first blue organic light-emitting layer and a top surface of the first blue pixel electrode is less than a distance between a top surface of the second blue organic light-emitting layer and a top surface of the second blue pixel electrode.
