Abstract: An organic electroluminescence (EL) display panel includes pixels arranged in a matrix of rows and columns, and includes: a substrate; pixel electrode layers that are arranged on the substrate in the matrix; an insulating layer that is provided above the substrate and the pixel electrode layers, and has elongated openings and a grooved portion for each of the pixels, the openings extending in a column direction and being arranged in a row direction, the grooved portion having an upper opening and a bottom and being communicated with at least one of the openings in plan view; organic functional layers that are provided above the pixel electrode layers, and include light emitting layers in which organic electroluminescence occurs in the openings; and a light-transmissive counter electrode layer that is provided above the organic functional layers. Cross-sectional profiles of the openings taken along the row direction are uniform in the column direction.

Abstract: A display unit is provided with a plurality of pixels that are two-dimensionally arranged and each include an organic electroluminescence element emitting light of one of a plurality of colors. The pixels are arranged along one direction for each of light emission colors. The pixels each include a first insulating film, a second insulating film, and an organic layer. The first insulating film has openings for the respective pixels. The second insulating film extends along the arrangement direction for each of the light emission colors, in a region between pixels of different light emission colors, out of the plurality of pixels, on the first insulating film. The organic layer is formed in each of the openings, and includes a light-emitting layer. The first insulating film includes a recess that connects together the openings of pixels of the same light emission color, out of the plurality of pixels.

Abstract: A display unit includes a plurality of pixels and a first insulating film. The plurality of pixels are arranged in matrix in a first direction and a second direction. The first insulating film is provided between adjacent pixels of the pixels, and has first openings in light-emitting regions of the respective pixels. The first insulating film has, between pixels adjacent in the second direction of the pixels, a second opening extending in the first direction, and a remaining part inside the second opening.

Abstract: An organic electroluminescence (EL) display panel includes pixels arranged in a matrix of rows and columns. The pixels each include a lower layer, an inner insulating layer, an application-type functional layer, and an upper electrode that are layered in this order. The lower layer includes a lower electrode. The functional layer includes a light-emitting layer. The inner insulating layer has one or more openings in which the lower layer is exposed. The openings each have a width increasing toward the upper electrode and have a slope toward a periphery of the pixel. In plan view, the openings are constituted from a plurality of elongated opening pieces.
