摘要：
A liquid crystal shutter array requiring no separate focusing lens system. Microlenses for focusing the light incident upon a matrix of pixel electrodes are formed in a transparent substrate of the shutter assembly. A refractive index of light of each of the microlenses is set in a manner such that the incident angle .theta. of the light incident on the liquid crystal of the shutter through the microlenses satisfies; ##EQU1## where P, a, and d respectively represent the size of each of the photomasks, the length of a portion wherein each of the photomasks and corresponding ones of the pixel electrodes overlap, and the thickness of the transparent substrate on the light output side.
