Abstract: A display device includes a first substrate, an organic EL layer formed on the first substrate and curved in each pixel, and color filters disposed in the respective pixels, and curved to match the organic EL layer. With this configuration, a change in the chromaticity and brightness of the display device depending on a viewing angle of a user is reduced.

Abstract: In an organic EL display device having plural organic EL elements each including an organic light emitting layer, an upper electrode formed on an upper side of the organic light emitting layer, and a reflective layer formed on a lower side of the organic light emitting layer, in which an image is displayed on a side of the organic light emitting layer on which the upper electrode is formed. The reflective layer in each of the organic EL elements includes a first plane, a second plane formed on a side lower than the first plane; and an inclined plane formed between the first plane and the second plane, and linearly inclined at a given angle equal to or higher than 35°, and equal to or lower than 55°.

Abstract: An OLED display panel is provided which can control the problem of shedding even in high definition panels. Metal wiring 5 which conducts with an earth line of a flexible printed substrate 15 is provided on a substrate 1. A display area 2 comprised from a plurality of OLED elements is provided at the center of the substrate 1 and four low resistance metal films 3 are provided along each of four edges of the display area 2 on a surface of insulation films 8, 10 at the periphery of the display area 2. Among these, one low resistance metal film 3 conducts with the metal wiring 5 via a contact 3a.
