Abstract

PURPOSE:To facilitate an operation and to decrease the man-hours of production by integrating the holding of a color liquid crystal panel and an outside frame shielding plate and the protection of connecting points of the input terminals of the color liquid crystal panel and a liquid crystal driving circuit with a silicone rubber spacer. CONSTITUTION:An IC 2 for driving a liquid crystal is connected via an anisotropic conductive film 3 to the color liquid crystal panel 1 by applying a pressure at a high temp. A silicone rubber spacer 5 for protecting this connecting point and the parts exposed with the input terminal 4 of the color liquid crystal panel 1 and for fixing and holding the outside frame shielding plate 6 and the color liquid crystal panel 1 is stuck to the connecting point and the outside frame shielding plate 6 is superposed thereon. A back light 7 and a signal processing substrate 8 are mounted and the outside frame shielding plate 6 is fixed thereto. A silicone rubber material is used rubber spacer 5 and is coated with adhesive on one side. The surface coated with the adhesive is stuck to the entire length on the side of the input terminals 4 of the color liquid crystal panel 1 along the end faces of the color filters facing the input terminals 4 of the liquid crystal panel 1.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color liquid crystal display device.

[0002]

2. Description of the Related Art Conventionally, this type of color liquid crystal display device is
As shown in FIG. 2, a rubber-like silicon rubber spacer 5 is sandwiched between the outer frame shield plate 6 serving as a housing and the color liquid crystal panel 1 for holding and holding the color liquid crystal panel 1, and on the other hand, in the vicinity thereof. The liquid crystal driving IC 2 is pressed at a high temperature through the anisotropic conductive film 3 to the input terminal 4 of the color liquid crystal panel 1 located at, and a UV curable resin 9 or a silicone resin is applied to the connection point for mechanical and temperature / humidity stress protection. It had a coated structure.

SUMMARY OF THE INVENTION A method for fixing and holding an outer frame shield plate and a color liquid crystal panel of the above-mentioned conventional color liquid crystal display device, and ultraviolet curing to a portion where a liquid crystal driving IC is connected to an input terminal of the color liquid crystal panel. The resin or silicon-based resin coating structure has a structure in which the position where the silicon rubber spacer for fixing and holding is fixed and the position where the ultraviolet-curing resin or silicon-based resin is applied are close to each other, resulting in a severe work precision. There is a problem that the man-hours for manufacturing are large and the capital investment is large because the work forms of both are different.

An object of the present invention is to provide a color liquid crystal display device which is easy to work and which can reduce the number of manufacturing steps and the capital investment.

[0005]

SUMMARY OF THE INVENTION The present invention is a color liquid crystal display device in which a liquid crystal drive circuit and a signal processing circuit are connected to a color liquid crystal panel and a backlight is mounted and fixedly held by an outer frame shield plate which is a housing. In this case, the color liquid crystal panel and the outer frame shield plate are fixedly held and the input terminal of the color liquid crystal panel and the connection portion of the liquid crystal drive circuit are protected by an adhesive silicon rubber spacer. Is characterized by.

[0006]

[Function] By stacking and fixing the outer frame shield plates, the silicon spacer attached to the color liquid crystal panel side is pressed by the fixing pressure, and the silicon spacers are brought into close contact with the connection terminal between the input terminal of the color liquid crystal panel and the liquid crystal driving IC. The connection points are protected mechanically or from the environment of temperature and humidity, and at the same time the outer frame shield plate and the color liquid crystal panel are fixed and held.

Embodiments of the present invention will now be described with reference to the drawings.

1 (A) and 1 (B) are a sectional view of an embodiment of the present invention and an enlarged sectional view of an essential part thereof.

As shown in FIGS. 1 (A) and 1 (B), a liquid crystal driving IC 2 is connected to a color liquid crystal panel 1 through an anisotropic conductive film 3 by applying pressure under high temperature, and the connection point and the color are connected. A silicon comb spacer 5 is attached to protect the exposed portion of the input terminal 4 of the liquid crystal panel 1 and to hold the outer frame shield plate 6 and the color liquid crystal panel 1 together. 8 is attached and the outer frame shield plate 6 is fixed to form a liquid crystal display device.

The silicon comb spacer 5 is made of a silicon rubber material and is coated with an adhesive 5a on one surface. The thickness is the inner surface of the outer frame shield 6 and the color liquid crystal panel 1.
The thickness is about twice the width of the gap with the surface of the input terminal 4, the width is the width that covers the exposed portion length of the input terminal 4 and the connection portion of the liquid crystal driving IC, and the adhesive 5a coated surface of the color liquid crystal panel 1 is The surface of the input terminal 4 is attached to the entire side (scanning electrode and signal electrode) of the input terminal 4 of the color liquid crystal panel 1 along the end face of the color filter.

[0011]

As described above, in the color liquid crystal display device of the present invention, the outer frame shield plate serving as a housing, the spacer for fixing and holding the color liquid crystal panel, and the liquid crystal driving to the input terminal of the color liquid crystal panel are driven. The production method is simplified by attaching a silicone rubber spacer coated with an adhesive that can cover both the IC and the UV curable resin used to protect the mechanical and temperature / humidity environment from the environment. Is reduced, the work man-hours and material costs can be reduced to about 1/2, and the investment of resin coating equipment and environment maintenance equipment can be significantly reduced.
