To provide a self-luminous display panel structure that enables high definition, and reduces a change in chromaticity of emitted light when a display image is viewed in an oblique direction.SOLUTION: A self-luminous display panel includes a plurality of light emitting elements 100 having a different light emitting color for each sub pixel 100se constituting a pixel, a plurality of column banks 122Y arranged between the light emitting elements 100 in the row direction and extending in the column direction, and a light-shielding film 133 having an opening 133a at a position facing each of the light emitting elements 100 in a plan view on the downstream side of the light emitting element 100 in the emission direction, and in a plan view, a distance between the edge of the opening 133a of the light-shielding film 133 in the row direction and the light emitting element 100 is different depending on the emission color of the light emitting element 100 by making the width of a portion located closer to the light emitting element 100 different in the width in the row direction of the column bank 122Y adjacent to the light emitting element 100 in the row direction.SELECTED DRAWING: Figure 2 【課題】高精細化が可能であり、かつ、斜め方向から表示画像を見たときの出射光の色度変化を低減する自発光表示パネルの構造を実現する。【解決手段】画素を構成する副画素１００ｓｅごとに発光色が異なる複数の発光素子１００と、行方向における発光素子１００と発光素子１００との間に配され、列方向に延伸されてなる複数の列バンク１２２Ｙと、発光素子１００の出射方向の下流側に、平面視において各発光素子１００と対向する位置に開口１３３ａが設けられた遮光膜１３３とを備え、平面視において、行方向における遮光膜１３３の開口１３３ａの縁と発光素子１００との距離は、発光素子１００と行方向に隣り合う列バンク１２２Ｙの行方向の幅のうち、発光素子１００の側に位置する部分の幅を異ならせることにより、発光素子１００の発光色に応じて異なる。【選択図】図２
