Abstract
An improved liquid crystal device and manufacturing method for same are described. In the device, a pair of substrates, between which a liquid crystal layer is disposed, is joined with pillars inbetween functioning as spacers which are provided of photocurable resin by photolithography. With this structure, the spacers can be in surface contact with the inside surfaces of the substrates on which electrode arrangement and active devices are formed.
