示装置を提供することにある。In view of the above-mentioned problems with the conventional technology, the purpose of the invention is to prevent the display quality from being degraded even when observed from a direction slightly tilted than usual, due to transmission through the disordered area of the liquid crystal alignment film in or around the sealing material. An object of the present invention is to provide a liquid crystal display device in which transmitted light is not visually observed.

けることによって達成される。The above purpose is to provide a liquid crystal display device in which a plurality of liquid crystal display elements are arranged in a stacked manner and a backlight is provided behind them, and a mask is used to block light that passes through the sealing material of the liquid crystal display elements and the surrounding area thereof. This is achieved by providing it between the liquid crystal display elements.

示素子２を積層配置し、下からバックライト３の照射光
を当てて上から表示パターンを観察する点、前記第２図
の従来とＩＵｌ−である。FIG. 1 shows an example of a two-layer liquid crystal display device (for example, for the purpose of reducing the coloring phenomenon described in Nikkei Enochtronics, October 1987 issue, pages 84-88), in which an upper liquid crystal display element 1 and a lower liquid crystal display element 2 are arranged in a stacked manner. This is different from the conventional method shown in FIG. 2 in that the display pattern is observed from above by applying the light from the backlight 3 from below.
本発明ｌこおいては、液晶表示素子のシール材、例えば
紫外線硬化性樹脂８を透過するバックライト３の照射光
１０を遮断するマスク１１５：上下両液晶表示素子１，
２の間に設けた点に特徴がある。In the present invention, a mask 115 for blocking the irradiation light 10 of the backlight 3 that passes through the sealing material of the liquid crystal display element, for example, the ultraviolet curable resin 8: both the upper and lower liquid crystal display elements 1,
The feature is that it is placed between 2.
ここでマスク１１の光透過窓はシール材８およびその近
辺領域を覆う大きざとする。Here, the light transmitting window of the mask 11 is made large enough to cover the sealing material 8 and its surrounding area.

、その材料を金色。By configuring the pot in this manner, the light that passes through the sealing material 8 and its inner vicinity is blocked and cannot be seen even when viewed from the arrow direction 12 in the drawing, and if the mask 11 is rubbed against the black pot, the liquid crystal display The effective display area is outlined in clear black. In addition, a material that does not allow light to pass through the mask 11 is used, and the material is gold in color.
