Abstract

PROBLEM TO BE SOLVED: To simplify a structure for mounting a display device, and to prevent the generation of the non-uniformity of display by constituting this display device mounting structure of a holding part for holding the display device, a display cover having protruding parts for maintaining the holding force of the holding part, and a supporting member for fixing the display cover. SOLUTION: A holding part 301b for holding a film liquid crystal device 302 being a display device is formed at an outer peripheral part of a film liquid crystal device cover 301. Then, a protruding part 301a extended to the inner peripheral direction is formed at the lower part of the cross-sectional direction of the holding part 301b so that the film liquid crystal device 302 can be prevented from being released when a holding force between the holding part 301b and the film liquid crystal device 302 can not be maintained due to an outer force. Then, the film liquid crystal device 302 is hold and fixed along the curved shape of a supporting member by the elasticity of the film liquid crystal device 302 itself so that the structure for mounting the film liquid crystal device 302 itself can be sharply simplified, and the generation of the non- uniformity of display due to a pressurizing force from the supporting member can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device mounting structure and an electronic / electronic device having the structure.

[0002]

2. Description of the Related Art FIGS. 1 and 2 show a first conventional example and a second conventional example in a conventional display device mounting structure, respectively. A film liquid crystal device is a bendable liquid crystal display device having a transparent electrode, a liquid crystal material, and the like between upper and lower flexible substrates. The first conventional example has a structure in which a display device is attached by bonding, and FIG. 1 is a sectional view showing the structure.

In FIG. 1, a film liquid crystal device 101 is attached to a support member 103 having a curved surface formed on an upper surface of a display device 101 by using an adhesive tape 102, an adhesive or the like on the curved surface side. FIG. 2 is a cross-sectional view showing a structure in which the display device is attached by sandwiching the display device. FIG. 2 is a sectional view showing a curved surface mounting structure by sandwiching the film liquid crystal device 202.

[0004] A film liquid crystal device 202 is arranged on a curved surface of a support member 203 having a curved surface formed on an upper surface thereof.
It was fixed by sandwiching it between the film liquid crystal device cover having the same curvature and the film liquid crystal device cover 201 having elasticity.

[0005]

In the first conventional display device mounting structure, since the display device is fixed to the support member with an adhesive, it is difficult to apply the adhesive to the support member with a uniform thickness. This caused variations in the thickness of the applied adhesive. For this reason, there is a problem that the display device is adhered to the unevenness due to the thickness variation, and the unevenness appears on the external appearance, and uniform display cannot be performed. In addition, when an adhesive or a pressure-sensitive adhesive is used, stress is applied to the entire lower surface of the display device, and a gap is generated between the upper and lower substrates of the display device, which causes a problem that display unevenness occurs. Further, even when the display device is to be replaced for some reason, it is extremely difficult to separate the display device from the support member without breaking the display device because the display device and the support member are bonded. There was also a problem that it had to be exchanged with it.

Next, in the second conventional example, when the display device is to be displayed with an arbitrary curvature, the shape of the upper surface of the support member and the curvature of the lower surface of the display device cover are processed with the same curvature. There was a problem that had to be done. Further, since the entire upper surface of the support member presses the display device, if the pressing force is weak, a gap is generated between the display device cover and the display device,
On the other hand, there is a problem that the appearance is deteriorated, and if the pressing force is strong, display unevenness occurs.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a support member for supporting and fixing a film liquid crystal device, a curved surface for guiding the film liquid crystal device, and a plurality of projections facing the curved surface along the curved surface. And a structure in which a stress from another component is not applied by holding and fixing along the curved shape of the support member by elasticity of the film liquid crystal device itself.
