ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ultra-large liquid crystal channel with improved viewing angle characteristics. More specifically, the liquid crystal channel is divided into at least four parts, and a rubbing process is applied so that the good viewing direction of each part is approximately at the center of the liquid crystal panel.

時の方位である。A commonly used liquid crystal panel is a 90° twisted TN type liquid crystal panel. This TN
A method for manufacturing a molded liquid crystal panel will be explained based on the drawings. FIG. 1 is an explanatory diagram showing the rubbing direction of the upper and lower substrates of a liquid crystal panel according to the prior art. In this TN type liquid crystal panel, two substrates each coated with a wiring film are subjected to a rubbing treatment in the direction of the arrow 1.2 using cotton cloth, chemical fiber, etc., as shown in FIG. 1, for example. The two substrates are placed facing each other at a predetermined distance, and the liquid crystal material is sealed. If you use a liquid crystal material that has a certain amount of left-handed chiral material added to it, you can create a left-handed 90° twisted T.
N-type LCD panels can be created. Note that the curved arrow 3 represents the twisting direction of the liquid crystal molecules from the upper substrate to the lower substrate. The TN type liquid crystal panel has a narrow viewing angle characteristic, and the direction in which the display can be seen well, that is, the good viewing direction is almost limited to the direction indicated by the arrow. For example, in the liquid crystal panel shown in Figure 1, the good viewing direction is 6 on the dial of a so-called analog clock.
It is the direction of time.

としての機能を果たす。In this way, if the rubbing direction of the upper and lower substrates and the twisting direction of the chiral substance are specified, the good viewing direction is limited. When this liquid crystal panel is used for a small display device such as a wristwatch or clock, the viewing position of the display device is constant, so that it can be sufficiently observed and functions as a display device.

くい。FIG. 2 is an explanatory diagram showing a general ultra-large liquid crystal panel and the position of the observer's eyes. However, when observing an ultra-large LCD panel from the front, for example, if the good viewing direction is the so-called 6 o'clock direction, the upper half will look good because it is viewed from the good viewing direction, but the lower half will look good. It is very difficult to see because the part must be viewed from the 12 o'clock direction.
そのため頭を動かす等を行い一良（見える位置に目を移

あった。As described above, among ultra-large liquid crystal panels, a normal TN type liquid crystal panel cannot be observed in its entirety at a glance.

FIG. 4(aL) (b) is an explanatory diagram showing the rubbing direction of the upper substrate and the lower substrate, respectively.Furthermore, FIG. 5 is an explanatory diagram showing the good viewing direction in each part of the liquid crystal panel according to the present invention.Transparent electrode is applied in a predetermined shape.

て組み合わせ−シール材７によりシールを行う。The remaining three quarters are covered with a mask so that only a quarter of the upper substrate 5 is exposed, and only the quarters are rubbed in the direction of the arrow in FIG. 4(a). Similarly, rub the remaining portion in the direction of the arrow, quarter by quarter. In this way, the upper substrate is divided into four parts, and each part is subjected to a prescribed rubbing process. The lower board is also divided into four parts, and each quarter part is shown in Figure 4(b).
Perform the rubbing process in the direction of the arrow as shown. Thereafter, as shown in FIG. 5, the corners a-b and c-d of the upper substrate 5 are lowered and sealed by the combined sealing material 7.

く観察できるものである。Furthermore, by enclosing a liquid crystal substance 8, a liquid crystal panel as shown in FIG. 3 can be produced. If a left-handed chiral substance is added to the liquid crystal material 8 in advance, the liquid crystal panel becomes a left-handed TN type liquid crystal panel. Therefore, in the upper right corner of FIG. 5, the good viewing direction is the so-called 7:30 direction. Also, 4:30 at the top left, 1:30 at the bottom left, and 1:30 at the bottom right.
The direction will be 00:30. In this way, the liquid crystal panel is manufactured so that a good viewing direction exists at the center of the liquid crystal panel in any of the quarters. Therefore, even when looking around the entire ultra-large liquid crystal panel, the whole can be clearly observed at a glance.
