Patent ID: 8858287

Claim:
A manufacturing method of an organic EL display device which includes a first substrate on which organic EL layers are formed in a matrix array, a second substrate which is flat and faces the first substrate in an opposed manner, and a sealing material which is formed in an annular shape between inner peripheries of the first substrate and the second substrate, the manufacturing method of an organic EL display device comprising the steps of: forming the organic EL layers on a lower electrode, an upper electrode on the organic EL layers, and a protective film on the upper electrode, wherein the second substrate is flat; forming a sealing material made of an ultraviolet-ray curing resin in an annular shape on the periphery of the second substrate, and forming a half-cured sealing material for stopping a gel-state desiccant by radiating ultraviolet rays to the sealing material; arranging the gel-state desiccant inside the half-cured sealing material using the half-cured sealing material as a stopper; adhering the first substrate and the second substrate, and filling a region surrounded by the first substrate, the second substrate and the sealing material with the gel-state desiccant; and forming the half-cured sealing material into a completely cured sealing material, wherein the gel-state desiccant is sandwiched between the protective film and the second substrate.
