ORGANIC EL DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE ORGANIC EL DISPLAY DEVICE
First Claim
1. An organic EL display device, comprising:
- lower electrodes that are arranged in each of pixels within a display area, made of a conductive material, and controlled in potential for each of the pixels;
an upper electrode that is arranged to cover the pixels, and made of a conductive material;
a first organic layer that is arranged between the lower electrodes and the upper electrode, and formed of a plurality of layers including a light emitting layer which is made of an organic material that emits light;
a laminated auxiliary line that has at least a first auxiliary line and a second auxiliary line made of a conductive material, and laminated on each other in order, and extends in one direction between two of the pixels adjoining each other within the display area; and
a second organic layer that is formed of a plurality of the same layers as the first organic layer, and arranged in contact with the first auxiliary line in a connection hole opened in the second auxiliary line so as to come out of contact with the first organic layer,wherein the upper electrode is arranged in contact with the first auxiliary line around the second organic layer so as to embed the connection hole.

Abstract
An organic EL display device includes a first organic layer that is arranged between lower electrodes and an upper electrode, and formed of a plurality of layers including a light emitting layer, a laminated auxiliary line that has a first auxiliary line and a second auxiliary line, and laminated on each other in order, and extend in one direction between two of pixels adjoining each other, and a second organic layer that is formed of a plurality of the same layers as the first organic layer, and arranged in contact with the first auxiliary line in a connection hole opened in the second auxiliary line so as to come out of contact with the first organic layer, in which the upper electrode is arranged in contact with the first auxiliary line around the second organic layer so as to embed the connection hole.

9. A method for manufacturing an organic EL display device, comprising the steps of:
-
forming an first auxiliary line and a second auxiliary line each made of a conductive material in order as a laminated auxiliary line forming step; overetching the second auxiliary line to form a connection hole, and expose the first auxiliary line as an overetching step; forming a first organic layer that is formed of a plurality of layers including a light emitting layer made of an organic material which emits light, and a second organic layer that is arranged on the first auxiliary line through the connection hole, and is discontinuous to the first organic layer at the same time as an organic layer forming step; and forming an upper electrode that is made of a conductive material, comes in contact with the first auxiliary line through the connection hole, and covers pixels as an upper electrode forming step, after the organic layer forming step. - View Dependent Claims (10, 11, 12, 13)
