<p>The purpose of the present invention is to provide a highly reliable color filter substrate applicable to an image display device, in particular, a color filter-type organic EL display, and to realize and provide at a low cost and simply an image display device having excellent sharpness and contrast, and high display quality. This color filter substrate can be used in an image display device equipped with an organic electroluminescence element. The color filter substrate has a red colored layer, a green colored layer, and a blue colored layer, an overcoat film, and an inorganic barrier film, and is characterized in that the amount of N-methylpyrrolidone generated from the color filter substrate when the same is heated up to 300°C in a helium atmosphere is 0.02-0.5ppm with respect to the mass of the color filter substrate.</p> |
