A light-emitting element display device includes: a display area which has an organic insulating layer that is made of an organic insulating material; a peripheral circuit area which is disposed around the display area and which has the organic insulating layer; and a blocking area that is formed between the display area and the peripheral circuit area. The blocking area includes: a first blocking area configured by only one or a plurality of inorganic material layers between an insulating base substrate and an electrode layer which covers the display area and is formed continuously from the display area, and which configures one of two electrodes for allowing the light emitting area to emit the light; and a second blocking area including a plurality of layers configuring the first blocking area, and a light emitting organic layer.

Display device

The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.

Organic electroluminescent display device

A display device, which includes a display region in which a plurality of pixels are arranged, includes a first organic insulating film, a first groove, which exists in a frame shape surrounding the display region to separate the first organic insulating film, a first inorganic partition portion, which is arranged in the first groove, and is made of an inorganic insulating material that exists in a frame shape surrounding the display region, a second organic insulating film formed above the first organic insulating film and the first inorganic partition portion, and a second groove, which exists in a frame shape surrounding the display region to separate the second organic insulating film, and is located inside the first groove in plan view.

In a display device in which an OLED is formed by a separate coating method, improving the accuracy of vapor deposition position and reducing display defects are established. In the array substrate, a display unit that displays an image configured with a plurality of pixels is formed. A first convex portion and a second convex portion are provided on a surface of a boundary region between the pixels of the array substrate. A first organic layer including a layer exhibiting a first emission color is stacked on the pixel electrode of the pixel, and second organic layers including a layer exhibiting a second emission color are stacked on the pixel electrode of the pixels. The first organic layer is provided to cover only the first convex portion. The second organic layers are provided not to cover any one of the first convex portion and the second convex portion.
