Abstract: In an organic EL display device, pixels constituted by sub-pixels of red (R), green (G), blue (B) and white (W) are formed without using a color filter. RGB sub-pixels of RGBW sub-pixels constituting a pixel include only respective light-emitting regions of respective corresponding colors. A W sub-pixel is configured such that a plurality of partial regions constituted by different types of light-emitting regions are arranged adjacent to each other, and that the plurality of partial regions are driven by a common pixel circuit.
