A liquid crystal device comprising a power source for supplying power between the pair of transparent electrodes is provided in front of the blinkable light source, and the liquid crystal device transmits light when the light is on and when the light source is off. A signal lamp in which the light source is not visible when the light is turned off, characterized in that the liquid crystal device is provided with means for turning on and off a voltage applied between transparent electrodes so as to block light. (2) The signal lamp according to claim 1, which is a utility model registration, wherein a transparent colored plate whose surface is coated with a transparent light-diffusing paint is provided between the liquid crystal device and the light source. (3) Claim No. 2 for utility model registration in which the surface of the transparent colored plate coated with transparent light-diffusing paint faces the light source.
Signal lights as described in section. (4) The signal lamp according to claim 2 or 3 of the utility model registration claim, wherein a transparent substrate having a transparent light-reflecting film formed thereon is disposed between the transparent colored plate and the light source. (5) The signal lamp according to any one of claims 1 to 4, wherein the liquid crystal is a nematic liquid crystal. (6) The signal lamp according to claim 5, wherein the liquid crystal is encapsulated in a capsule, and a plurality of capsules are fixed to the pair of transparent electrodes. (7) The signal lamp according to claim 5, wherein the liquid crystal is arranged between the pair of transparent electrodes so as to have a twisted nematic effect.
