Abstract:
1. An organic EL display device comprising: a first substrate having an organic EL element on an inner surface thereof; and a second substrate, which is a flat glass substrate, for hermetically sealing the organic EL element with a sealing material interposed between the first and second substrates at a peripheral portion of the second substrate, wherein the second substrate has a transparent drying material on an inner surface thereof at a position inwardly from the sealing material, wherein a display image is visible through the transparent drying material and the second substrate, wherein within a bank-shaped frame which is separate from the second substrate and which is formed on the inner surface of the second substrate, the transparent drying material is formed by a dispenser and spread by a squeegee, and drying a solution within the bank-shaped frame formed on the inner surface of the second substrate, wherein the transparent drying material is provided with varying thickness and with a surface having unevenness so that an angle formed by a normal line on the second substrate and a normal line at different positions on the surface having unevenness of the transparent drying material varies, and the variation of the angle at the different positions is greater than 0 degrees and no greater than 53 degrees so that distortion and disturbance including luminance nonuniformity of an image resulting from the surface unevenness of the transparent drying material are absorbed to enable obtaining of a sharp image, and wherein at least one of a color filter, a color film and a polarizing film is arranged on the outer surface of the second substrate.
