Organic electroluminescence display apparatus

The color filter is a color conversion filter having a color conversion function, wherein white light is emitted from an organic EL to the color filter, transmitted through the color filter, and thereby split into three colors of blue, green and red. At such time, through the absorption of shorter wavelength light that is not usually transmitted through the color filter and through the emission of light having a longer wavelength than that of the absorption region, the transmitted light of the color filter is added to the emitted light to increase brightness.
