1. An exposure system, comprising a mask plate and a principal reflection structure that is provided above the mask plate, wherein the mask plate comprises a light transmitting region and a light shielding region, the pattern of the light transmitting region corresponds to the pattern of the region to be exposed of a first substrate, a light reflecting region for reflecting exposure light is provided in the light shielding region, and the pattern of the light reflecting region corresponds to the pattern of the region to be exposed of a second substrate; and when exposure light irradiates on the mask plate, passes through the light transmitting region of the mask plate and exposes the first substrate, the light reflecting region of the mask plate reflects the exposure light to the principal reflection structure, and the principal reflection structure further reflects the light, which is reflected by the light reflecting region, to the region to be exposed of the second substrate to expose the second substrate.
