Electroluminescence display apparatus

A color display device, in which a display pixel having an emissive element is disposed for every color, wherein an emissive area of said display pixel is set for every color in accordance with:

• the emission efficiency of said emissive element disposed at said display pixel;
• the chromaticity of each color emitted by respective emissive element;
• and
• the chromaticity of a target display white of the display device, and wherein
• said emissive element is an organic electroluminescence element comprising an emissive layer using an organic compound between a first electrode and a second electrode, and the emissive area of said display pixel is set by smaller one of direct contact areas between an emissive element layer including said emissive layer of said organic electroluminescence element and said first electrode, and between said emissive element layer and said second electrode.

A color display device, in which a display pixel having an emissive element is disposed for every color, wherein an emissive area of said display pixel is set for every color in accordance with:

• the emission efficiency of said emissive element disposed at said display pixel;
• the chromaticity of each color emitted by respective emissive element;
• and
• the chromaticity of a target display white of the display device, and wherein:
• said emissive element is an organic electroluminescence element composed by forming in sequence a first electrode, an emissive element layer including at least an emissive layer using an organic compound, and a second electrode;
• the emissive element is separated by an insulating film between layers of said first electrode and said emissive element layer in the proximity of an edge of said first electrode;
• and
• the emissive area of each display pixel in the organic electroluminescence element of the display pixel is set in accordance with an area of said insulating film covering the edge of said first electrode.

A color display device having display pixels for red, for green, and for blue, respectively having an emissive element, wherein an emissive area of said display pixels for red, for green, and for blue is set on the basis of:

• the emission efficiency of the emissive element of each display pixel;
• and
• a luminance ratio of red to green to blue in accordance with each chromaticity of red, green, and blue emitted by respective emissive element of the display pixel, and with the chromaticity of a target display white of the display device, and wherein:
• said emissive element is an organic electroluminescence element composed by forming in sequence a first electrode, an emissive element layer including at least an emissive layer using an organic compound, and a second electrode;
• the emissive element is separated by an insulating film between layers of said first electrode and said emissive element layer in the proximity of an edge of said first electrode;
• and
• the emissive area of each display pixel in the organic electroluminescence element of the display pixel is set in accordance with an area of said insulating film covering the edge of said first electrode.
