A light reflector of which the bidirectional reflectance R 1 is from 90 to 120% when the light entrance angle is 15° and the light acceptance angle is 0° and the bidirectional reflectance R 2 is from 85 to 110% when the light entrance angle is 75° and the light acceptance angle is 0°. The light reflector has high reflectivity and attains brightness improvement even in underlight-type backlights.
