Abstract: A display unit includes multiple pixels, a first electrode, a partition wall, a light emission layer, and a second electrode. The multiple pixels each have a light emission region and a non-light emission region along a first direction. The first electrode is provided in the light emission region in each of the multiple pixels. The partition wall is provided between each two of the pixels that are adjacent to each other in a second direction. The second direction intersects the first direction. The light emission layer covers the first electrode and is provided in the light emission region and the non-light emission region in a continuous manner. The second electrode faces the first electrode across the light emission layer.

Abstract: A display apparatus includes a display panel and a driving circuit. The display panel includes signal lines extending in a column direction, scanning lines extending in a row direction, and lead-out lines extending in the column direction. Each of the lead-out lines intersects with corresponding one of the scanning lines at an intersection and is electrically coupled to the corresponding one of the scanning lines at a node. The node is disposed at the intersection or in a region surrounding the intersection. The driving circuit supplies corresponding one of the signal lines with a signal pulse corresponding to an image signal, and supplies corresponding one of the lead-out lines with a selection pulse having a peak value based on a distance from one end of the corresponding one of the lead-out lines to the corresponding node, after increasing the peak value with an increase in the distance.

Abstract: A display unit includes a substrate including a pixel region including a plurality of pixels and a peripheral region. The display unit includes a plurality of first electrodes, wherein each of the plurality of first electrodes is in a corresponding pixel of the plurality of pixels. The display unit includes a second electrode opposed to the first electrode, wherein the second electrode is common for all of the plurality of pixels. The display unit includes an organic layer between the second electrode and the plurality of first electrodes, wherein the organic layer includes a light-emitting layer. The display unit includes a wiring layer between the substrate and the plurality of first electrodes. The display unit includes an auxiliary electrically-conductive layer including an organic electrically-conductive material, wherein the auxiliary electrically-conductive layer is electrically coupled to the second electrode. The auxiliary electrically-conductive layer is in a recess in the wiring layer.

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.
