ABSTRACT:
A method of manufacturing a liquid crystal display element comprising a pair of substrates and a liquid crystal composition injected into and cured in an evacuated cell constituted with the substrates, wherein the degree of vacuum in the cell is from 0.5 to 10 mmHg, the composition forms a liquid crystal and polymer composite in which the nematic liquid crystal is dispersed and held in the resin matrix, and light transparent-scattering states are attained by agreement and disagreement between the refraction index of the liquid crystal and the refractive index of the resin matrix under control of an electric field applied across the electrodes. Residual bubbles left in the cell are disposed in the peripheral portion not constituting the display portion or in the pocket portion formed integrally to the peripheral portion.
