PROBLEM TO BE SOLVED: To provide a liquid crystal device which has higher resolution and a wider detection range for the intensity of environmental light, a light emission system, and electronic equipment. SOLUTION: The liquid crystal device has a liquid crystal panel 11 which has a TFT array substrate 22 and a counter substrate 23 between which a liquid crystal layer 21 is sandwiched, first to third photodetecting elements 35 to 37 which receive the environmental light and acquire intensity information on the environmental light, and a back light control circuit which controls the display state of an image displayed on the liquid crystal panel 11, and at least one of the first to the third photodetecting elements 35 to 37 is different in sensitivity to the environmental light from other photodetecting elements.
