する。First, a film roll 20 around which a PET film having a thickness of 0.1 mm is wound is prepared, and a PET film 21 fed from a material feeding section is placed in a continuous vapor deposition device 22 using a generally used continuous vapor deposition method. After being conveyed, one side of the film is sequentially coated with a silicon oxide film with a thickness of 500 angstrom. The coating of the silicon oxide film can prevent intrusion of water and oxygen, which are generally harmful to the organic EL display device.
Similar effects can be expected by using silicon nitride instead of silicon oxide. The film coated with silicon oxide is sent to the ultraviolet curable resin coating step. The ultraviolet curable resin 24 applied in this ultraviolet curable resin coating step is
5 wt% to 30 wt% of fine plastic beads having a spherical diameter of 3 μm to 10 μm are mixed. Further, the materials were selected so that the difference in refractive index between the base UV curable resin and the fine beads was 0.1 or more. UV curable resin 24 containing these fine beads
Is applied from the resin supply unit 25 onto the film passing between the die coater 23 and the metal roll 26 whose distance is precisely controlled. The distance between the die coater 23 and the metal roll 26 is adjusted so that the thickness of the ultraviolet curable resin containing fine beads on the film is about 0.05 mm. The film thus coated with the ultraviolet curable resin containing fine beads is sent to the microlens transfer step. It is desirable that the microlenses 12 to be formed on the film are densely arranged in the film plane as shown in FIG. The cross-sectional shape of the transfer roll 27 used in the step here is shown in FIG. The roll has a concave cross section so that a convex lens is formed by transfer. Further, as shown in FIG. 5, fine irregularities 51 having a surface roughness Ry of about 0.1 micrometer are formed in the surface of each microlens transfer shape. In addition, this microlens was formed into a lens shape by cutting using a diamond bite, and then fine irregularities were applied to the surface by a sandblast method. A film coated with the ultraviolet curable resin containing fine beads is passed between the roll die 27 and the nip roll 28 thus produced. The UV curable resin containing fine beads is filled in the concave shape of the mold roll. Immediately after that, the ultraviolet curable resin containing fine beads is cured by the ultraviolet rays emitted from the ultraviolet ray irradiator 29, is released from the mold roll by the release roll 30, and is integrated with the film while transferring the shape of the mold roll. Becomes Then, the molding film edge cutting mechanism 200 cuts and deletes the incompletely molded parts at both ends of the molding film. The removed unnecessary portion is wound by the cutting ear winding mechanism 201. The formed film is then completed film winding mechanism 2
It is wound up by 02, and the organic EL sealing film is completed.

It is sequentially laminated.

ＥＬ表示装置１００が完成する。Next, a method for laminating the above-mentioned organic EL sealing film on the organic EL display element substrate will be described. As shown in FIG. 7, the adhesive 71 is applied to the periphery of the organic EL display element substrate 10 in advance by a dispenser or the like, and is supplied one by one from the buffer section into the laminating apparatus 81 as shown in FIG. The inside of the laminating device 81 is held in a vacuum, and the organic EL sealing film fed out from the organic EL sealing film feeding portion 82 by a predetermined amount is sequentially attached to the organic EL display element substrate. Then, the curing unit 83 is heated to a constant temperature to heat the organic E
The adhesive around the L display element substrate 10 is cured. In addition, in synchronization with the movement to the curing section, the next organic EL display element substrate is supplied and the same lamination is performed. In the organic EL display device that has been completely sealed after curing, the trimming mechanism 84 trims an unnecessary sealing film so that the peripheral wiring portions are exposed. Thus, the polymer organic EL display device 100 is completed.

Since the display device is provided with the silicon oxide film layer on the film, it is possible to prevent moisture and oxygen from entering from the outside, and thus to maintain the life of the display device for a long time. Further, in the case of a display such as a mobile phone that does not require a wide viewing angle, the microlens shape 12a in which the radius of the spherical surface of each microlens provided on the surface is increased as shown in FIG. It is possible to provide a high-luminance image with a viewing angle of 91 and low power consumption. When used for a display for a personal computer, a home television, or the like, the microlens shape 12b is formed by making the radius of the spherical surface of the microlens smaller than that of the display for a mobile phone as shown in FIG. ,
It is possible to observe an image in a wide visual field range 102.
