As shown in Figure 10 E, on the substrate 102 that provides barrier rib 108, form organic luminous layer 110.
As shown in Fig. 7 F, be parallel to negative electrode 112 barrier rib 108 formation and that be connected to second circuit 152 that exposes by contact hole 175 by metal material being deposited on provide on the substrate 102 that organic luminous layer 110 is provided.
As mentioned above, comprise pseudo-barrier rib 109 according to the organic EL display apparatus of second embodiment of the invention, it is connected at each barrier rib 108 at viewing area P1 place and between sealant 125 and organic EL array.Pseudo-barrier rib 109 prevents that together with barrier rib 108 sealant 125 from flowing into the task of organic EL array in encapsulation process.Further, between sealant 125 and organic EL array, provide the grating 206 of the puppet insulation with concave surface and convex portions, thereby will flow into the concave region 206a of the pseudo-insulation of the sealant 125 immersions grating 296 of organic EL array.This prevents that sealant 125 from flowing into organic EL array.Therefore, can prevent the infringement of the organic luminous layer 110 that sealant 125 causes and therefore can prevent luminous efficiency and deterioration of image.
As mentioned above, according to the present invention, provide the pseudo-barrier rib that is connected to each barrier rib 108 and is positioned at non-display area.Therefore, can prevent the infringement of the organic EL array that causes by the sealant that when lid engages with substrate, uses and therefore can prevent luminous efficiency and deterioration of image.
In addition, according to the present invention, between the pseudo-barrier rib at sealant and place, viewing area, provide insulation film with concave surface and convex portions.Therefore, can prevent the infringement of the organic EL array that causes by the sealant that when lid engages with substrate, uses and therefore can prevent luminous efficiency and deterioration of image.
Although the embodiment shown in the above-mentioned accompanying drawing explains that to the present invention those of ordinary skill in the art should understand the present invention and not limited by embodiment, and can carry out various modifications to it under the situation that does not break away from spirit of the present invention.Therefore, only define scope of the present invention by accessory claim and equivalent thereof.
