Organic electroluminescent display apparatus

An organic electroluminescent display apparatus, comprising:

• a substrate, an organic electroluminescent device, and a color filter substrate;
• wherein the organic electroluminescent device comprises a pixel definition layer, a first electrode layer, a light-emitting function layer, a second electrode layer, and a first passivation layer;
• wherein the pixel definition layer has an opening region and a non-opening region, and the pixel definition layer is arranged on the substrate;
• wherein the first electrode layer is arranged on the opening region of the pixel definition layer;
• wherein the light-emitting function layer is arranged on the first electrode layer;
• wherein the second electrode layer is arranged on the pixel definition layer and the light-emitting function layer;
• wherein the first passivation layer is arranged on the second electrode layer;
• wherein the color filter substrate comprises a color resistance unit, a black matrix, and a second passivation layer;
• wherein the black matrix is arranged on the first passivation layer and is arranged opposite to the non-opening region of the pixel definition layer;
• wherein the color resistance unit is arranged on the first passivation layer and is adjacent to the black matrix;
• wherein the second passivation layer is arranged on the color resistance unit and the black matrix;
• the second passivation layer is composed of a single-layer film or multi-layer film.
