Abstract
A color display device having an organic EL element for each display pixel. The element emissive area in the display pixel of any color among the R, G, and B display pixels has a size that is different from the element emissive area of the display pixel of another color. Furthermore, the element emissive areas in the display pixels for R, G, and B are designed to take into consideration not only the emission efficiency of the emissive elements of the display pixels but also the luminance ratio of red to green to blue in accordance with the chromaticity of the target display white of the display device and with the chromaticity of each red, green, and blue color emitted by the emissive elements of the respective display pixels. This prevents the organic EL elements of colors for which the emission efficiency is low from selectively deteriorating, and facilitates the control of white balance in the color display.
