Point light sources (130) arranged in an array are provided on the side of the first substrate (110) distant from the second substrate (120). The side of the first substrate (110) close to the second substrate (120) is provided with optical coupling devices (140) having one-to-one correspondence to the point light sources (130). The sides of the optical coupling devices (140) distant from the first substrate (110) are provided with a grating layer (150). A liquid crystal layer (161) is provided between the first substrate (110) and the second substrate (120). The optical coupling devices (140) are configured to reflect the light emitted by the corresponding point light sources (130) and passing through the first substrate (110) and reaching the optical coupling devices (140) into the first substrate (110).
