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 device includes a pixel including a plurality of sub-pixels. Each of the plurality of sub-pixels includes: a light-emission region; and a non-light-emission region other than the light-emission region. The light-emission region includes one or more effective light-emitting parts in which a first electrode, a light emitting layer, and a second electrode are stacked in order, and a light guide provided on side of the one or more effective light-emitting parts on which light is extracted.

Abstract: A display unit includes a plurality of light-emitting sections and an optical filter. The plurality of light-emitting sections emit color light beams having different colors. The optical filter is disposed on light emission side of the plurality of light-emitting sections, and transmits the color light beams while selectively removing a part of a wavelength band of the color light beams. The optical filter includes the first filter layer and the second filter layer. The first filter layer transmits a first band including a center wavelength out of the wavelength band of each of the color light beams, and removes a second band that is at least a part of a band other than the first band. The second filter layer reduces transmissivity of a third band that is a part of the first band of at least one color light beam out of the color light beams.
