The lower polarizer 21 ' The angle between the optical axis of the optical axis and the long axis direction of the liquid crystal molecules in the lower alignment control film 24 'is? In the clockwise direction, and the optical axis of the upper polarizing plate 21 and the liquid crystal molecules in the upper alignment control film 24 If the component in the major axis direction is β in the clockwise direction, the color of the portion where no voltage is applied is expressed as follows.

그러나 이러한 액정표시소자는 상하편광판(21)(21')이 유리기판(22)(22')과 접착 고정되어 있으므로 그 자체로 대형광고판에 사용하기에는 시각적 효과를 얻을 수 없는 문제점이 있었다.However, the liquid crystal display device has a problem that the upper and lower polarizing plates 21 and 21 'are adhesively fixed to the glass substrates 22 and 22' so that visual effects cannot be obtained by themselves.

상기 제1 및 2의 기판(1)(1')은 각각 그 대향하는 내면상에 소정 패턴의 전극(5)(5')이 형성되고 그 내측에 배향막(6)(6')이 피막되어 있다.The substrates 1 and 1 'of the first and second substrates respectively have a predetermined pattern of electrodes 5 and 5' formed on opposite surfaces thereof, and an alignment layer 6 and 6 'are coated therein. have.

배향막(6)(6')은 액정분자가 높은 배향각을 갖게하는 층으로 Sio를 진공증착하여 만들어진다.The alignment films 6 and 6 'are made by vacuum-depositing Sio as a layer which has a high alignment angle of the liquid crystal molecules.

제3도는 Sio 각주(6a)가 유리기판(1)(1')에 증착된 형상을 도식적으로 확대하여 보인 것이다.3 shows a schematic enlarged view of the shape in which the Sio footnote 6a is deposited on the glass substrate 1, 1 ′.

배향막(6)(6')의 내측에는 절연막(7)(7')이 형성되어 있다.An insulating film 7 (7 ') is formed inside the alignment film 6 (6').

절연막(7)(7')은 유리기판으로 부터 Na+이온이 액정(3)측에 침입하여 손상시킴을 방지하기 위한 것이다.The insulating films 7 and 7 'are for preventing Na + ions from penetrating into the liquid crystal 3 side from the glass substrate and damaging them.

At this time, the lower alignment layer 6 having the optical axis of the rotating lower polarizing plate 8 'and the footnote 6a of Sio. Angle between the long axis of the liquid crystal molecules in the direction of the projection on the glass substrate, the optical axis of the rotating upper polarizing plate 8 and the horizontal direction of the liquid crystal molecules in the alignment film 6, and By the four independent variables of the angular velocity of the rotating upper and lower polarizers 8 and 8 'and ④ the twist angle of the liquid crystal, the background color of the liquid crystal display (the part where no voltage is applied) shows the splendor of the total natural color over time. The selected area (where the voltage is applied) is black.

이러한 본 고안은 상기 상하 편광판(8)(8')을 회전시키는 대신 고정하고 상하 유리기판(1)(1') 사이의 구성인 액정셀(12)을 회전시켜도 상기의 효과를 얻을 수 있다.The present invention can achieve the above effect even if the liquid crystal cell 12, which is a configuration between the upper and lower glass substrates 1 and 1 ', is fixed instead of rotating the upper and lower polarizing plates 8 and 8'.

이상에서와 같은 본 고안 액정표시소자는 전류 소비가 많은 LED를 이용한 대형 액정표시소자를 대치하여 저 전류소비로 작동할 수 있고, 색도 완전 풀칼러의 배경색을 갖을 뿐아니라 모터의 각속도를 조절하여 기존의 광고판에서 보지 못하는 휘황찬란함을 보게되는 효과가 있다.The liquid crystal display device as described above can operate at a low current consumption by replacing a large liquid crystal display device using a large current consumption LED, and has a full color background color as well as a conventional angular speed of the motor. The effect of seeing the splendor that is not seen in the billboard.
