Abstract

PURPOSE:To provide the liquid crystal display device of a large screen having good visibility by using a specific material for a sealing material of liquid crystal display devices. CONSTITUTION:The liquid crystal display devices 10a to 10d are constituted by combining two sheets of substrates 11, 12 consisting of glass by the sealing material 13 and clamping liquid crystals 14 in the spacings therebetween. This sealing material 13 consists of a transparent material and its refractive index (m) is the same 1.5 as the refractive index (n) of the substrates 11, 12. The liquid crystal display devices 10a to 10d constitute one screen by flatly disposing their display surfaces. The display surfaces are irradiated with the light rays of back lights 15a to 15e from behind the display surfaces. Light shielding plates 16 are provided between the adjacent liquid crystal display devices 10a to 10d. The generation of the scattering of the light by the sealing material 13 is prevented by using such sealing material 13. The display is executed without glowing between the adjacent liquid crystal display devices even when light is made incident from the direction diagonal with the liquid crystal display devices.

On the other hand, it is possible to block light coming in from a vertical direction, but it is not possible to block light coming from an oblique direction. For this reason, the light incident from the oblique direction enters the seal portion of the liquid crystal display device 3 and becomes scattered light, and the space between the adjacent liquid crystal display devices 3 shines, which is very unsightly.

The sealant of the liquid crystal display is transparent, and its refractive index m satisfies the relationship of 0.9 n ≦ m ≦ 1.1 n with respect to the refractive index n of the substrate of the liquid crystal display.

Further, since the refractive index of the sealant is almost the same as the refractive index of the substrate that constitutes the liquid crystal display, light propagates without refraction between the sealant and the substrate. As a result, even when light is incident on the liquid crystal display from an oblique direction, display can be performed without light emission between adjacent liquid crystal displays.
