DISPLAY PANEL AND PROCESS FOR PRODUCING THE SAME

摘要

A display panel of enhanced antiweatherability which during the production thereof can avoid exposure to high temperature. In particular, organic EL device (100) as a display panel, comprising non-alkali glass base plate (10), organic EL laminate (20) superimposed on the base plate (10) and sealing plate (30) provided so as to cover the organic EL laminate (20). The sealing plate (30) has 2.0 mm wide peripheral protrusion (31) provided around central depressed part (32). The organic EL laminate (20) is superimposed on the base plate (10) and comprises conductive film (21) consisting of ITO film, organic EL laminated film (22) superimposed on an upper surface of the conductive film (21), upper transparent electrode (23) superimposed on an upper surface of the organic EL laminated film (22) and extraction electrode (24) connected to the upper transparent electrode (23). The base plate (10) and the peripheral protrusion (31) of the sealing plate (30) are joined in sealed relationship to each other through weld layer (40) consisting of a solder disposed in a sealing zone provided therebetween.
