ABSTRACT:
First, a plurality of organic EL elements are formed on a substrate. The electron injection electrode of an organic EL element has a stacked layer structure of a metal thin film and a metal oxide film. A sealing agent is provided on the upper portion and outer periphery of the plurality of organic EL elements on the substrate, so as to surround the entire perimeter of the plurality of organic EL elements. A sealing plate is bonded to the upper face side of the sealing agent with a color filter sandwiched therebetween. As the sealing agent, a resin adhesive is used from which a solution extracted in accordance with the SEMI standard G29-1296 after curing has a pH of not less than four nor more than ten. It is preferable that the resin adhesive has a light transmittance of 70% or more on average in the wavelength range of 450 nm to 800 nm, with the variation range of the light transmittance in the wavelength range of 450 nm to 800 nm being not more than ±10% for the average light transmittance.
