ORGANIC ELECTROLUMINESCENCE DISPLAY PANEL AND METHOD OF MANUFACTURING THEREOF

摘要

An organic EL display panel has a transistor array substrate, an inter-layer insulation film, pixel electrodes, an organic EL layer, and a common electrode. The transistor array substrate has drive units, including TFT elements. The inter-layer insulation film covers the transistor array substrate, and has contact holes corresponding to the drive units. The pixel electrodes on the inter-layer insulation film correspond to the drive units, and are electrically connected thereto via the contact holes. The organic EL layer covers regions where the pixel electrodes are and are not disposed. The common electrode covers the entire organic EL layer. Organic EL layer regions corresponding to the contact holes of the inter-layer insulation film and between neighbouring pixel electrodes have greater electrical resistance than other regions.

主权项

1. An organic electroluminescence display panel, comprising:
a transistor array substrate on which are disposed a plurality of drive units 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 drive units; a plurality of pixel electrodes disposed on the inter-layer insulation film in correspondence with the drive units, and electrically connected to the drive units 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 another region of the organic electroluminescence layer.
