    • 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.
    • 首先,在基板上形成多个有机EL元件。 有机EL元件的电子注入电极具有金属薄膜和金属氧化物膜的叠层结构。 在基板上的多个有机EL元件的上部和外周设置密封剂,以围绕多个有机EL元件的整个周边。 密封板与夹在其间的滤色器的上表面侧接合。 作为密封剂,使用树脂粘合剂,其中固化后根据SEMI标准G29-1296提取的溶液具有不小于4或不超过10的pH。 优选树脂粘合剂在450nm〜800nm的波长范围内的透光率平均为70%以上,450nm〜800nm的波长范围的透光率的变化范围不大 比平均透光率的±10%。
