Abstract: In a sealing method of a top-emission organic light emitting element, in the case of using a method of filling with a sealing agent between a substrate mounted with pixels and an opposed substrate, the organic light-emitting element is degraded by ultraviolet rays when irradiation of the ultraviolet rays is performed toward the pixels in order to achieve ultraviolet curing of the sealing agent filling on the pixels. It is an object of the present invention to propose a method for avoiding this phenomenon to provide an organic light-emitting device with superior stability. In order for a sealing agent 13 filling on a pixel portion 14 to have a larger absorbance to ultraviolet rays, an ultraviolet-absorbent material is dispersed in a sealing agent to make an adjustment so that the absorbance of ultraviolet absorption wavelength of 400 nm or less becomes 1 or more.
