Abstract:
1. A panel light comprising: a light-emitting device, the light-emitting device comprising: a first substrate; a transparent second substrate; and an organic light-emitting element between the first substrate and the transparent second substrate, the organic light-emitting element comprising: a first electrode over an insulating surface of the first substrate; an organic light-emitting layer over the first electrode, the organic light-emitting layer comprising an electroluminescent organic compound; and a transparent second electrode over the organic light-emitting layer; wherein a first sealing agent is provided at a periphery of the light-emitting device, wherein a second sealing agent comprising an ultraviolet curable resin and an ultraviolet absorbent is filled between the transparent second electrode and the transparent second substrate, wherein the first sealing agent is selected from a material having a higher viscosity than the second sealing agent, wherein the ultraviolet absorbent is dispersed in the ultraviolet curable resin, wherein the second sealing agent has an absorbance of 1 or more to a wavelength of ultraviolet rays irradiated for curing the ultraviolet curable resin, and wherein the first sealing agent comprises an opening.
