Abstract: Since a film, which is the upper layer of an interlayer insulating film and has a fast etching rate, does not have dense film quality, moisture is entered from the end portion of a substrate, and it is likely that display unevenness and the like occur. A manufacturing method of a display device includes the steps of: forming a first contact hole on the first interlayer film; forming a second interlayer film on the first interlayer film and in the first contact hole, the second interlayer film having a lower layer film and an upper layer film having an etching rate faster than an etching rate of the lower layer film; forming a second contact hole on the second interlayer film; and removing at least a part of the upper layer film.

Abstract: An organic EL display device includes in order from a substrate side: a metal layer; an insulating layer formed on the metal layer; a first electrode layer formed on the insulating layer; an organic layer formed on the first electrode layer; and a second electrode layer formed on the organic layer. The metal layer is for use as a reflective layer configured to reflect, on a surface of the metal layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.

Abstract: A method of manufacturing a display device includes forming a three-layer laminate by laminating a first transparent conductive film, a metal film, and a second transparent conductive film in order from a substrate side. The three-layer laminate forms a plurality of anode electrodes arranged in a pixel region and a plurality of dummy electrodes arranged on an outer side of the pixel region. The method of manufacturing a display device also includes subjecting the second transparent conductive film and the metal film to etching and subjecting the first transparent conductive film to etching. A density of a pattern of the plurality of dummy electrodes is reduced as a distance from the pixel region is increased.

Abstract: When an alignment film is applied to the whole surface of a substrate, adhesion intensity between a sealing material and the alignment film is further deteriorated. A display device includes an array substrate having a first alignment film, a counter substrate having a second alignment film, a liquid crystal layer in contact with the first alignment film and the second alignment film, and a sealing material for bonding the first alignment film and the second alignment film together, wherein the sealing material is provided with a portion adapted to increase the area of the adhered portion.

Abstract: According to one embodiment, a liquid crystal display includes first light sources disposed side by side in a scan direction, a first light guide to guide the light emitted from the first light sources in a first direction, second light sources disposed side by side in the scan direction, a second light guide to guide the light emitted from the second light sources in a second direction, and a light source driver to independently turn on and turn off the first and second light sources. The light source driver sequentially turns on and turns off the first light sources in a first period. The light source driver sequentially turns on and turns off the second light sources in a second period.
