摘要： PROBLEM TO BE SOLVED: To facilitate quality control of a display panel and improve quality and reliability. SOLUTION: The display panel comprises a translucent glass substrate SUB1 which has a display region AR consisting of a pixel circuit in which a great number of display pixels SP constructed of a light emitting element and an active element are arranged in matrix form on a main surface and a sealing glass substrate SUB2 which covers the main surface of this translucent glass substrate SUB1 and is airtightly sealed by interposing a sealing agent SEL at the peripheral part of the translucent glass substrate SUB2. A dummy pixel DP constructed of an light emitting element and a passive element is arranged at the outside of the display region AR on the main surface of the translucent glass substrate SUB1, and the display pixel SP and the dummy pixel DP have respectively a positive electrode AD, an organic multi-layer film ELM, and a negative electrode KD formed in order in lamination on the main surface of the translucent glass substrate SUB1. In the dummy pixel, the organic multi-layer film ELM is exposed by removing a part of the negative electrode KD, and a current passage is formed between the other remaining part of the negative electrode AD and the positive electrode AD.

摘要： PROBLEM TO BE SOLVED: To provide a light-emitting display device using an organic light-emitting element which emits light with high brightness at low current by a structure of enlarging an effective area of a light-emitting part composed of an organic light-emitting layer and effectively taking out light from the organic light-emitting layer toward a transparent substrate side.
SOLUTION: A multi-layer structure film composed of a lower part transparent electrode EA formed at a transparent substrate SUB side, an organic light-emitting layer LM, and an upper reflection electrode EK formed on the upper layer of the organic light-emitting layer LM is so made as to have a concave ALC1 formed so as to become concave toward the transparent substrate SUB side and to have a plurality of protrusions PJ1 becoming convex toward an opposite side of the transparent substrate SUB. The effective area of the organic light-emitting layer LM is made larger than the area of a pixel part by arranging a dome-shaped part OPAS of an organic insulation layer between the concave ALC1 and the transparent substrate SUB, to take out almost all emitted light toward the transparent substrate SUB.

摘要： PROBLEM TO BE SOLVED: To provide an organic EL (electro-luminescence) display whose light emitting portion deterioration concerning its bank films is suppressed, and whose facing electrode or light emitting material layer poor formation defect and poor picture display defect accompanying this is suppressed.
SOLUTION: The organic EL display has at least one electrode, a light emitting material layer and another electrode which are made in laminated formation on a pixel region of a substrate, and has the bank film which is formed being marked off adjacent other pixel regions. The light emitting material layer is formed in such a way that it covers a bank film aperture area and a bank film side wall area. The another electrode is formed as a common electrode for all pixels. The bank film is composed of an inorganic material layer, and its side wall has tilting less than 85°.
