Abstract: A plurality of pixels are arranged on the substrate. Each of the pixels is provided with an EL element which utilizes as a cathode a pixel electrode connected to a current control TFT. On a counter substrate, a light shielding film, a first color filter having a first color and a second color filter having a second color are provided. The second color is different from the first color.

Abstract: By repeating a purification process of a light-emitting organic compound several times, a thin film made of the light-emitting organic compound to be used in an EL display device contains ionic impurities at the concentration of 0.1 ppm or lower and has a volume resistivity in the range of 3×1010 Ωcm or larger. By using such a thin film as a light-emitting layer in the EL device, a current caused by reasons other than the carrier recombination can be prevented from flowing through the thin film, and deterioration caused by unnecessary heat generation can be suppressed. Accordingly, it is possible to obtain an EL display device with high reliability.
