用いており、偏光板は省略してある。Conventionally, in this type of device, various proposals have been made to colorize the display. FIG. 3 shows an example thereof, which is colorized by a color filter. In FIG. 3, 1 is a viewpoint,
Reference numeral 2 is a liquid crystal element (hereinafter referred to as LCD), 3 is a color filter, 4 is a colored portion, and 5 is a light source. According to this configuration, the light from the light source 5 is applied to the colored portion 4 of the color filter 3.
By passing through, it is possible to give coloring to the display by the LCD 2. Further, recently, in order to eliminate parallax due to the thickness of the glass, as shown in FIG. 4, there is also proposed a method in which a coloring layer 9 is provided on the transparent electrode 7b formed in a predetermined display pattern for direct coloring. ing. In FIG. 4, 6a and 6b are glass substrates, and 7a and 7b.
Is a transparent electrode, 8a and 8b are alignment films, and 10 is a liquid crystal molecule. The one shown in FIG. 4 uses a TN type LCD, and the polarizing plate is omitted.

でないという問題がある。However, in these methods, when the display is turned off (when no voltage is applied between the pair of transparent electrodes), the transmittance and the hue when the display is turned off differ depending on the presence or absence of a color filter and the difference in the color of the filter. There is a problem that the display pattern and the display color are known in advance to the observer, and a sense of quality is not obtained.
本発明は上記問題に鑑みたもので、その目的とするとこ
ろは、表示オフ時に表示パターンおよび表示色が観察者
にわかってしまうことがないようにしたものである。The present invention has been made in view of the above problems, and an object thereof is to prevent an observer from seeing a display pattern and a display color when the display is turned off.
本発明は上記課題を達成するため、 一対のガラス基板と、この一対のガラス基板間に設けた

In the liquid crystal display element, wherein one of the electrodes is formed in a predetermined display pattern and a voltage is applied between the pair of transparent electrodes to perform the predetermined display, the predetermined display pattern is colored. A colored layer for display to be formed is provided in a portion corresponding to the transparent electrode formed in the predetermined pattern, and at least two or more non-displayed portions including the color of the colored layer for display are provided outside the predetermined display pattern. The colored layers for display are sequentially arranged from the colored layer for display.

表示用着色層および非表示用着色層の作用によりそれら
の混合色にて全体的に着色化する。In the above structure, when the display is turned on (when a voltage is applied between the pair of transparent electrodes), a predetermined display pattern is colored by the action of the display coloring layer. Also, when the display is off,
Due to the action of the display coloring layer and the non-display coloring layer, they are entirely colored with the mixed color thereof.
本発明によれば、表示オフ時には、全体的に着色化する

晶表示とすることができるという優れた効果がある。According to the present invention, when the display is turned off, the entire display is colored, so that the display pattern and the display color are not known to the observer, and thus a high-quality liquid crystal display can be obtained. There is an excellent effect.

FIG. 2 and FIG. 2 are configuration diagrams showing an embodiment thereof. FIG. 1 shows the display off state, and FIG. 2 shows the display on state. The light source is omitted in FIG. Further, in FIGS. 1 and 2, the same parts as those shown in FIG. 4 are designated by the same reference numerals, and a TN type LCD is used similarly to that shown in FIG. The polarizing plate is omitted. This embodiment is different from that shown in FIG. 4 in that the colored layer 1 is composed of R (red), G (green) and B (blue).
1 is formed in the entire effective visual field range at the same pitch and finely sequentially so that the colors are mixed with each other when viewed from human eyes at a distance used. Therefore, the transmittance and the hue when the display is off are the same in the effective visual field range. When displaying in white, as shown in FIG. 2, all three RGB colors may be turned on (voltage on). Further, in the case of displaying in green, the electrode may be provided only in the portion where the colored phase becomes G and only G is turned on. Intermediate colors can also be obtained by turning on the two colored layers at the same time. It is also possible to change the color in the same lighting segment by additive color mixing.

また、着色層は、ガラスの外側、内側、上基板、下基板
（光源側）、透明電極上、下どの位置に設けてもよい。Further, the colored layer may be provided at any position on the outside, inside, upper substrate, lower substrate (light source side) of the glass, on the transparent electrode, or below the glass.
