Abstract
An improvement in an electro-optical device, such as a liquid-crystal panel, having a pair of substrates and an optical modulating substance disposed between the substrates, comprising hard gap controllers of a material which cannot be heat-bonded to the substrates and soft gap controllers of a material heat-bondable to the substrates being mutually dispersed in the optical modulating substance between the substrates. These gap controllers effectively prevent distortion of the cell and eliminate degradation of the display quality which may otherwise be caused due to generation of interference color.
