PURPOSE:To reflect irregularly a glare of light during glare irradiation by providing a convex mirror on the reverse surface of a phase shift type liquid crystal element and interposing a light transmissive inclusion material whose refractive index is smaller than the optical refractive index of the substrate material of the liquid crystal display element between the liquid crystal display element and convex mirror. CONSTITUTION:The liquid crystal element 2 for a nonglaring mirror is constituted by installing the convex mirror 6 on the reverse surface of the phase shift type liquid crystal display element LCD4 across the ight transmissive inclusion material 5. The same material as the substrate material of the LCD4 is used preferably as the inclusion material 5 between the convex mirror 6 and LCD4 so as to secure the linearity of incident light. For example, when soda glass is used as the substrate material of the LCD4, a material is selected preferably as the inclusion material 5. Consequently, when there is intense incident light from the headlamps of a rear following vehicle, this light is reflected irregularity by the LCD4 without reaching the convex mirror 6.
