An EL display device with color filter capable of surpressing color mixture. The EL display device includes: a first substrate having lower electrodes, a pixel separation film that separates the lower electrodes from each other, and an EL layer of white light emission; a second substrate having a black matrix and a color filter; and a sealing layer, in which the following Expression is satisfied. W>2 tan(thetam)(HBM+H+HG+HS)-(WS+WBM) where W is a width of an aperture area, WBM is a width of the black matrix, WS is a width of the pixel separation films, HBM is a thickness of the black matrix, H is a thickness of the color filter, HG is a distance between a front surface of the pixel separation film and a color filter rear surface, HS is a height of the pixel separation film, and thetam is a critical angle between the second substrate and an air. |
