The light guide plate is provided with a light exit region on a side close to the blue phase liquid crystal layer, the light exit region is arranged to correspond to the light shielding part in position, and in case the electrode layer does not apply a driving voltage to the blue phase liquid crystal layer, the collimated natural light which passes through the light exit region is incident on the light shielding part and is blocked by the light shielding part. The electrode layer is configured to apply the driving voltage to the blue phase liquid crystal layer to form a liquid crystal grating, and the blue phase liquid crystal receives different driving voltages at different positions in one of grating periods of the liquid crystal grating, so that the collimated natural light is diffracted by the liquid crystal grating and exits through the opening region.
