본 고안은 액정의 편향각을 이용하여 도형이나 문자를 나타내는 투과형액정표시 소자에 관한 것이다.The present invention relates to a transmissive liquid crystal display device that displays a figure or a character by using the deflection angle of the liquid crystal.
오늘날 사용되고 있는 투과형 액정표시소자는 보다 발달된 선명한 화상을 나타내는 것을 원하고 있다.Transmissive liquid crystal display devices used today want to display more advanced and clear images.
종래의 투과형 액정표시소자는 제1도에 도시된 바와같이 편광판(2)가 부착된 유리기판(1)에 나타내고자 하는 문자나 도형을 전극으로 패턴하고 그위에 배향막(3)이 증착되어 구성된 기판과 기판사이에 전계효과에 의해 일정한 편향각을 갖는 액정(4)와 유리막대의 스페이스(5)을 개재시켜 구성된다.In the conventional transmissive liquid crystal display device, as shown in FIG. 1, a substrate formed by patterning letters or figures to be displayed on the glass substrate 1 having the polarizing plate 2 with electrodes and having an alignment layer 3 deposited thereon is formed thereon. And the liquid crystal 4 having a constant deflection angle between the substrate and the substrate through the space 5 of the glass rod.
이와같이 구성된 투과형 액정표시소자는 소자에 전압이 인가되기 전에는 액정 (4)의 편향각이 검정색이나 유색의 편향각을 갖고 있다가 소자에 전압이 인가되면 액정(4)의 편향각이 바뀌면서 문자나 도형이 표시부에 나타나게 된다.In the transmissive liquid crystal display device configured as described above, the deflection angle of the liquid crystal 4 has a black or colored deflection angle before the voltage is applied to the device. Will appear on the display.
이때, 투과형 액정표시소자의 스페이서(5) 부분에 흰색점이 발생되는데 이는 스페이서(5)가 유리로 구성되어있기 때문에 외부광원(a)에 의한 빛이 유리로 구성된 스페이서(5)를 투과하여 표시부에 배시되는 것이며, 다른 부위는 액정(4)가 정상동작을 하기 때문에 상기와 같은 흰색점이 표시부에 배시되지 않는 것이다.At this time, a white spot is generated in the spacer 5 portion of the transmissive liquid crystal display device. Since the spacer 5 is made of glass, the light emitted by the external light source a passes through the spacer 5 made of glass. The other part is that the white point as described above is not displayed on the display part because the liquid crystal 4 operates normally.
상기와 같이 표시부에 흰점이 생기는 것을 방지하기위해 종래에는 원형 프라스틱을 스페이서로 사용하고자 하였으나 이것 또한 스페이서가 구형을 이루고 있기 때문에 일정한 장소에 고정이 되어야할 스페이서가 이동을 하여 한곳에 뭉치는 현상이 발생되어 또 다른 문제점으로 된다.In order to prevent the occurrence of white spots on the display unit as described above, in the past, a circular plastic was used as a spacer. However, since the spacer has a spherical shape, the spacer to be fixed at a certain place is moved and aggregated in one place. This is another problem.
본 고안은 전기한 제반 문제점을 해소하고자 안출한 것으로서 외부광원에 의해서 표시부에 흰점이 발생되는 것을 방지하여 고품위화 할수 있는 투과형 액정표시소자를 제공함에 그 목적이 있다.An object of the present invention is to provide a transmissive liquid crystal display device capable of improving the quality by preventing white spots from occurring on a display unit by an external light source.
본 고안은 상기 목적을 위해 투과형 액정표시소자의 스페이서(5)를 빛이 투과되지 못하는 검정 또는 유체색으로 착색된 스페이서를 사용함으로서 외부 광원에 의해 빛이 투과되는 현상을 방지토록 하고 있다.The present invention prevents light from being transmitted by an external light source by using the spacer 5 of the transmissive liquid crystal display device colored with black or fluid color to which light is not transmitted.
이때 본 고안의 착색유리 스페이서는 투과형 액정표시소자에 전압이 가해지지 않는 상태에 있을 때의 액정(4)의 색상과 같도록 선택하면 된다.In this case, the colored glass spacer of the present invention may be selected to be the same as the color of the liquid crystal 4 when the voltage is not applied to the transmissive liquid crystal display device.
이하 본 고안을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 측단면도로서 제1도와 동일한 구성에 대하여서는 동일부호로 지칭한다.2 is a side cross-sectional view of the present invention and the same components as those in FIG. 1 are referred to by the same reference numerals.
편광판(2)가 증착된 유리기판(1)상에 배향막(3)이 증착되고, 일정 편향각을 갖는 액정(4)과 착색유리로 구성된 스페이서(A)가 배향막(3) 사이에 개재되어 있다.An alignment film 3 is deposited on the glass substrate 1 on which the polarizing plate 2 is deposited, and a spacer A made of liquid crystal 4 and colored glass having a predetermined deflection angle is interposed between the alignment film 3. .
상기 구성을 갖는 투과형 액정표시소자는 외부광원(a)로 부터의 빛이 제2도에 도시한 바와같이 액정(4)와 착색 스페이서(A)를 투과하지 못하고 반사되어 표시부상에는 문자나 도형이 선명하게 배시된다.In the transmissive liquid crystal display device having the above structure, the light from the external light source a does not penetrate the liquid crystal 4 and the colored spacer A as shown in FIG. It is clearly displayed.
이와같이 본 고안의 투과형 액정표시소자의 스페이서(A)부분이 외부 광원에 의한 빛을 투과 시키지 않고, 흡수 및 착색하게 됨으로써 표시부상의 문자나 도형이 선명하게 되는 이점이 있다.As described above, the spacer A of the transmissive liquid crystal display according to the present invention is absorbed and colored without transmitting light by an external light source, so that letters and figures on the display portion are clear.
