    • 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%。

    • A process for manufacturing a high quality organic EL panel is provided. On a glass substrate is formed an organic EL element, on which is then deposited a protective film. The surface of the device substrate or the sealing substrate is treated with ozone or plasma, and then an adhesive is applied on the surface by screen printing. After placing the device substrate and the sealing substrate in a chamber in a vacuuming apparatus, the inside of the chamber is vacuumed to a pressure of P1. After leaving the substrates for a given period until foaming of volatiles contained in the adhesive ceases, a pressure in the chamber is increased to P2 for preventing foaming of the volatiles, and then the substrates are laminated. Then, the laminate is pressurized and heated for removing microspaces. Finally, the adhesive is cured using, for example, a UV lamp.
    • 提供一种制造高质量有机EL面板的方法。 在玻璃基板上形成有机EL元件,然后在其上沉积保护膜。 用臭氧或等离子体处理器件基板或密封基板的表面,然后通过丝网印刷将粘合剂施加在表面上。 将设备基板和密封基板放置在真空装置的室中之后,将室内抽真空至P1的压力。 离开基板一定时间后,粘合剂中含有的挥发物的起泡停止,将室内的压力提高到P2,以防止挥发物发泡,然后层压基板。 然后,将层压体加压并加热以除去微球。 最后,使用例如UV灯固化粘合剂。
