Description

[Detailed Description of the Invention] The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display constructed by interconnecting transmissive liquid crystal cells forming at least one pixel consisting of a plurality of picture elements. .

Generally, terminals for connecting wiring extending from electrodes inside the cell to a drive circuit are provided at appropriate locations around the liquid crystal cell. In a conventional liquid crystal display constructed by connecting a large number of such liquid crystal cells, each liquid crystal cell is arranged so that the wiring terminals of each liquid crystal cell are gathered in one place on the liquid crystal display for easy connection to a drive circuit. The wiring was installed between them. Therefore, it is necessary to leave sufficient space between each liquid crystal cell to allow these wirings to be formed, and as a result, it is difficult to arrange a large number of liquid crystal cells closely together in such a liquid crystal display. The drawback was that I couldn't do it.

Therefore, an object of the present invention is to provide a liquid crystal display constructed by connecting a large number of liquid crystal cells each having at least one pixel consisting of a plurality of picture elements, so that the liquid crystal cells are arranged as closely as possible to each other. An object of the present invention is to provide a liquid crystal display device that gives clearness to the entire screen of the display device.

Hereinafter, the liquid crystal display of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

Generally, in a transmissive liquid crystal cell 10 that forms at least one pixel consisting of a plurality of picture elements, a liquid crystal 12 is arranged between two opposing flat glass plates 11a and 11b, and Scanning lines and signal lines are formed extending vertically and horizontally on the inner surface of the substrate. This liquid crystal cell 10 further includes a color filter disposed on the outer surface of one of the flat glass plates for displaying a color as each picture element, and a mask for blocking the transmission of light from a light source between each picture element. We are prepared.

An embodiment of a liquid crystal display according to the present invention using such a liquid crystal cell 10 is shown in FIGS. 1 to 3. In the liquid crystal display 13 of the embodiment,
Each liquid crystal cell 10 is provided with a protruding end 14 in which one flat glass plate 11a is longer than the other flat glass plate 11b in the vertical direction, as shown in FIG. A plate having a property of transmitting light, that is, a transparent substrate 15 is attached to the outer surface of the other flat glass plate 11b of each liquid crystal cell 10, that is, the flat glass plate 11b having a shorter length in the vertical direction, Further, the one flat glass plate 11
A deflection filter 16 is attached to the outer surface of a. As is clear from FIG. 2, the above-mentioned light-transmitting substrate 15 has a length approximately equal to the length of the long flat glass plate 11a, where L is the height of the long flat glass plate 11a.

For convenience, a single liquid crystal cell 10 with a transparent substrate 15 attached thereto is referred to as a liquid crystal element, and each element is designated by reference numerals 17a, 1b, 17c, . . . . These liquid crystal elements are connected in the vertical direction and a plurality of columns in the horizontal direction constitute a liquid crystal display. At this time, the connection state of the liquid crystal elements in the vertical direction is as follows.

That is, as shown in FIG. 1, the liquid crystal element 17a and the liquid crystal element 17b adjacent thereto are arranged with their directions opposite to each other, and the liquid crystal element 1
The inner surface of the protruding end 14 of the flat glass plate 11a in 7a and the lower edge of the transparent substrate 15 of the liquid crystal element 17b, and the upper edge of the transparent substrate 15 of the liquid crystal element 17a and the protruding end of the flat glass plate 11a in the liquid crystal element 17b. 14 inner surfaces are overlapped and connected to each other.

Therefore, in other words, the liquid crystal elements 17a17b adjacent to each other in opposite directions are connected by mutual connection between the edge of the transparent substrate 15 and the liquid crystal cell 10 in each of the liquid crystal elements 17a17b. Next, other liquid crystal elements 17c above the liquid crystal element 17b are also connected to each other in the same manner as described above. In this way, a plurality of liquid crystal elements 17a, 17b, 17c, .

However, in reality, it is not necessary to form and arrange the transparent substrate 15 attached to the outer surface of the flat glass plate 11b of each liquid crystal cell 10 individually, that is, for each liquid crystal cell 10; 4
As shown in the figure, a transversely long translucent substrate 1
5 are arranged at intervals in the vertical direction, and these can be formed as a common substrate for the horizontal rows.
That is, each liquid crystal cell 10 is mounted between the light-transmitting substrates 15 with the inner surfaces of their protruding ends 14 overlapping the upper and lower edges of the substrates 15. A first panel is formed in which a plurality of vertical columns of such liquid crystal cells 10 are arranged horizontally along each common light-transmitting substrate 15, and a second panel similar to the panel facing the first panel is formed. The panel 2 is a flat glass plate 1 of each liquid crystal cell.
1b and the flat glass plate 11b of the liquid crystal cell of the first panel are positioned on the inside of both panels, and the liquid crystal cell 10 and the transparent substrate 15 are positioned to face each other in both facing panels. The liquid crystal display 13 shown in FIG. 1 is formed by polymerizing both panels.

In such a liquid crystal display 13, the protruding end 14 on the flat glass plate 11a of each liquid crystal cell 10
As shown in FIG. 5, a large number of wiring terminals, that is, cell side terminals 18 are formed on the inner surface, and the terminals 18
A part thereof is connected to an internal electrode (not shown) of the liquid crystal cell 10, and the other part is connected to a terminal formed on the inner surface of the protruding end 14 on the opposite side (the terminal is connected to the internal electrode (not shown) of the liquid crystal cell 10). It is connected to an electrode of a liquid crystal cell located above the liquid crystal cell (which is connected to its terminal via the wiring of the substrate 15 described later) via internal wiring of the liquid crystal cell.

On the other hand, regarding the transparent substrate 15, the flat glass plates 11a of each liquid crystal cell 10 adjacent above and below it
Terminals corresponding to the terminals 18 formed on the inner surface of the projecting end of the liquid crystal cell 10, as shown in FIG. Side terminals 19 are formed respectively. Each terminal 19 formed on both upper and lower edges of such a transparent substrate 15 is connected by a wiring 20 formed on the substrate 15. By the way, this transparent substrate 15 is attached to the flat glass plate 11b of another liquid crystal cell 10, and therefore each pixel 21 in that liquid crystal cell 10 is attached to the transparent substrate 15.
Visible through display. However, since there is a slight interval between the pixels 21 in this column, the wiring 20 avoids the pixel display area 22 on the translucent substrate 15 corresponding to the pixels of the liquid crystal cell 10 and connects the pixels 21 to each other. The substrate 15 corresponding to the spacing between
formed in the upper part.

In this way, the internal electrode terminals of the liquid crystal cells 10 in each column are centrally arranged at one location on the lower end or the upper end of the liquid crystal display via the wiring 20 on each substrate 15. And, because the wiring on the substrate for this purpose is not formed between special intervals, but instead uses the gaps between the pixel display areas of the corresponding liquid crystal cells,
The proximity of the liquid crystal cells arranged in the horizontal direction can be increased and they can be arranged closely to the extent that they are almost in close contact with each other. Note that such a light-transmitting substrate 15 may be completely transparent, but it may also be a substrate having a polarizing effect.

As described above, according to the liquid crystal display of the present invention, each of the liquid crystal cells arranged in the vertical direction is connected to the end of the translucent substrate, and at this time, the terminals formed at the connection ends of the liquid crystal cells are connected to each other. A terminal is formed on the connection edge of the translucent substrate so as to correspond to and contact with the substrate, and a wiring connected to the terminal and crossing the substrate in the vertical direction is passed between the pixel display areas corresponding to the pixels of the liquid crystal cell. By doing so, in addition to the wiring within the liquid crystal cell, the wiring can be further wired on the transparent substrate, and the combination structure of the transparent substrate and the liquid crystal cell can have substantially twice as many wiring patterns. Therefore, it is possible to use a liquid crystal cell with a large number of picture elements, and the clarity of the screen can be improved.
