Abstract

See full text

A light modulator includes a substrate providing an electro-optical effect and provided with first to third optical waveguides, a first modulation section that modulates a blue light flux passing through the first optical waveguide, a second modulation section that modulates a green light flux passing through the second optical waveguide, and a third modulation section that modulates a red light flux passing through the third optical waveguide, and L1S2>S3 are satisfied, where L1 represents the length of the first modulation section, S1 represents the distance between a first reference line and a first exit section, L2 represents the length of the second modulation section, S2 represents the distance between a second reference line and a second exit section, L3 represents the length of the third modulation section, and S3 represents the distance between a third reference line and a third exit section.
