Abstract

In a multi liquid crystal display device, the side surfaces of liquid crystal display panels are combined with each other, and each of the liquid crystal display panels includes a pair of substrates facing each other and having liquid crystal injected therebetween. An attachment film is attached to the side surface of the liquid crystal display panel and combined to the adjacent liquid crystal display panel. Each of the liquid crystal display panels are combined by attaching the attachment films to each other.

Claims

1. A liquid crystal display device comprises a plurality of liquid crystal display panels;

each having a front plate and a rear plate spaced apart from each other and a liquid crystal disposed between said front and rear plates, wherein the front and rear plates of each panel are sealed with strip-shaped films on at least one side of the panel;

such said side of one of the panels is attached to side of another one of the panels with respective strip-shaped film therebetween; and

a plurality of pixels formed on one of said plates are separated by a black matrix, wherein at least one row of pixels is located at an edge of said one of said plates;

such that a side of said at least one row of pixels coincides with the edge of the plate to which said films are respectively attached.

2. The liquid crystal display device according to claim 1, further comprising adhesive coating on sides of the front and rear plates, where said strip-shaped films are positioned with said coating to securely couple said strip-shaped films to the plates.

3. The liquid crystal display device according to claim 1, the width of said strip-shaped films is less than half of that of the black matrix.

4. A liquid crystal display device comprises multi-liquid crystal display panels;

each having front and rear plates spaced apart from each other with a liquid crystal therebetween;

each panel including a plurality of pixels surrounded on at least three sides thereof with a black matrix; and

wherein edges of adjacent said panels adapted to form a junction with each other include a strip-shaped film attached directly to the associated edge of said panel forming said junction without black matrix disposed therebetween.

5. The device of claim 4, wherein the attachment film is a strip-shaped film having a color the same as the color of the black matrix.

6. The device of claim 5, wherein a total thickness of said attachment films forming said junction is about equal to or less than the thickness of the black matrix formed between adjacent pixels of a respective panel.

7. The device of claim 5, wherein said strip-shaped films are preformed strips.
