The purpose of the present invention is to provide an organic electroluminescence image display device which exhibits excellent visibility, durability and light resistance, wherein a panel does not warp when the temperature within the device increases even if the device has a large screen. This organic electroluminescence image display device is at least provided with an organic electroluminescence element and a circularly polarizing plate having a ?/4 plate, wherein the ?/4 plate contains a cellulose acetate in which an acetyl group substitution degree is in the range of 2.00 and 2.70, and has a planar retardation value (Ro(550)) represented by formula (1) in the range of 100 and 180 nm, formula (1) being Ro(550)=(nx-ny)×d(nm), and a maximum planar elasticity of 4.0GPa or more when measured in an environment having a temperature of 23°C and a humidity of 55 RH%. |
