BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display panel formed by decorating panel substrates of cellular phones, digital cameras, televisions, computers, and other electronic devices, and a manufacturing method thereof.

In the case of decorating a panel substrate provided in an image display panel such as a conventional electronic apparatus and attaching an optical double-sided tape thereon, an air layer may be generated inside the step created by the decor. That is, as shown to Fig.6 (a), the back surface 21a of the transparent panel board | substrate 21 which displays an image is decorated, and this decorating layer (henceforth a "decoration layer") ( When the optical double-sided tape 23 is affixed on the upper surface 22a of 22 and the back surface 21a of the panel substrate 21, as shown in FIG. 6 (b), the panel substrate 21 and the decorative layer ( An air layer 25 such as an air pool is formed in the corner portion of the step 24 with the 22.

Thus, as described above, in order to remove the air layer 25 formed in the step 24 between the panel substrate 21 and the decorative layer 22, in the next step, the air layer 22 is Although it is also possible to perform the operation | work which extracts air, there exists a possibility that the air layer 25 may relapse over time by the restorability of the optical double-sided tape 23 after pressure defoaming. Moreover, there also exists a problem that it is difficult to stick the optical double-sided tape 23 to smoothing.

In addition, as shown in Fig. 6A, when the decorative layer 22 is formed by overlapping with, for example, two ink layers 22c and 22d, a step 22b is formed in the decorative layer 22. The width of the step 24 becomes large. In this situation, when the optical double-sided tape 23 is bonded to the back surface of the panel substrate 21 and the decorative layer 22, the optical double-sided tape 23 does not become smooth as shown in Fig. 6B. Deformation similar to the bent portion 29 occurs in the vicinity of the step 24. And when the other member 27 is affixed on the back surface of this optical double-sided tape 23, the member 27 is hard and does not deform | transform, and the panel substrate 21 by PET resin etc. is pulled toward the member 27 side, Attached in a deformed state, the inside of the panel substrate 21 is deformed into a curved shape 31 toward the back side. At this time, as shown in FIG. 7, when the image display panel 20 is seen from the front, the bent portion 29 of the optical double-sided tape 23 formed along the inside of the step 24 is decorated. There was a problem in that it appeared in a line shape along the inner vicinity of the layer 22.

As shown in Fig. 6A, when the through hole 26 and the like are formed in the decorating layer 22, as shown in Fig. 6B, the panel substrate 21 and the decorating layer are shown. When the optical double-sided tape 23 is stuck to the back surface of 22, and as shown in FIG. 6 (c), when another member 27 is affixed to the back surface of the optical double-sided tape 23 in a pressurized state, FIG. As shown in (d), the panel substrate 21 is attached while being forcibly pulled toward the member 27 side. For this reason, the panel substrate 21 in the site | part of the through-hole 26 becomes a shape distorted in concave shape to the back side.

Furthermore, as shown in FIG. 7, when the decorative part 28, such as a logo mark, is put on the back surface of the panel board | substrate 21, the cross-sectional shape becomes as shown to FIG. 8 (a). In this figure, the optical double-sided tape 23 is affixed on the back surface of the panel substrate 21 and the decorative part 28, and the optical double-sided tape 23 is formed in a wavy shape according to the thickness of the decorative part 28. As shown in FIG. And as shown to FIG.8 (b), (c), when the other hard member 27, such as a glass plate, is stuck to the back surface of the optical double-sided tape 23, between each decorative part 28, 28 The optical double-sided tape 23 is pulled toward the member 27 side and deform | transformed, and the panel substrate 21 which consists of PET resin etc. produces the convex-shaped deformation | transformation 21b to the front side for every decorative part 28. As shown in FIG. In addition, as shown in FIG. 7, the deformation | transformation 21b of this convex part becomes a circular distortion part 30 for every decorating part 28, and causes coarse deformation.

By the way, Patent Document 1 below discloses an image display apparatus and a manufacturing method thereof in which a bubble is not generated in a cured resin filled between a transparent panel and an image display unit side panel in a conventional image display apparatus.

However, this image display apparatus and its manufacturing method provide a notch in between spacers provided in the periphery of a transparent panel. In addition, the cured resin filled on the inside of the spacer, which is the upper surface of the transparent panel, is smoothed in the absence of bubbles by pressurization of the panel on the image display portion, and the excess cured resin is discharged from the cutout portion.

That is, in the image display apparatus of patent document 1 and its manufacturing method, since the cured resin is not apply | coated to the upper surface of each spacer, and the excess cured resin is made to discharge from the notch between a spacer and a spacer, it is transparent. The spacer provided in the periphery of a panel cannot be formed continuously, and it becomes a shape cut | disconnected in the middle for every notch.
