。In the illustrated liquid crystal panel, an unillustrated light source is installed below the panel container 1 (), and the light emitted from this is transmitted into the panel.
( ) Displays C. Rinawara, electric (to 3.4 l between
When voltage is not applied, the light emitted from the light source is blocked by the crystal 2, and when a voltage of 1 is applied, the liquid crystal 2 present between the electrodes 3 and 4 will move in the vertical direction. The light source light is transmitted through the transparent type iai.
Dimensional numbers or patterns of /l are displayed. At this time, reflection of external light is effectively prevented by the three-layer anti-reflection crotch, ensuring visibility of the display. It should be noted that electricity is supplied to the transparent electrode 4 by forming a three-layer reflective film with a li1]-structure and applying it to the transparent electrode for wiring as shown in the figure.

There is 5% culm degree over m>, and the back thorn; etc. are Table iJ, and 1
It is difficult to see the display because it is reflected in a. Then, add transparent type 1 to 4j1.
In the part where 1A /I is formed, the reflection of electricity (!11100) is added, and the reflection of the liquid crystal panel is q・15(
・reaches as much as 10%, and when voltage is applied without -C, the electric current (4 meter 4) appears to rise by 27, causing a false alarm.

0j, after forming a three-layer anti-reflection film, the transparent type (the part where the cutout 4 is not formed) (゛ means the reflectance of the liquid crystal panel is 1% Ct+ in the visible light region as shown in Figure 4). On the other hand, if an antireflection film is formed on the display surface 1a as described above even in the area where the transparent electrode 4 is formed, J: the reflectance of the reflection decreases, but As shown in FIG. 5, it still shows 5 to 6%, and problems such as the transparent mold 0^4 appearing to float upwards remain unresolved.

This anti-reflection film suppresses the reflection caused by the transparent type 4, and as shown in FIG. 6, the anti-DJ ratio of the liquid crystal panel is reduced to 1% or less even in the area where the transparent electrode 4 is formed.
