Abstract
A liquid crystal device is constituted by a pair of oppositely disposed substrates including a first substrate provided with a first alignment control layer which has been subjected to a uniaxial aligning treatment and a second substrate provided with a second alignment control layer which has not been subjected to a uniaxial aligning treatment, a sealing member disposed so as to seal up a peripheral portion of the first and second substrates to form a spacing therebetween, and a dispersion member (e.g., spacer beads or adhesive particles) and a liquid crystal disposed in the spacing while contacting the first and second aligning control layers. The dispersion member has been subjected to a surface treatment with a material constituting the second alignment control layer. The surface-treated dispersion member is effective in suppressing an occurrence of a reverse domain within a display region of the liquid crystal device, thus preventing flickering and improving a contrast.
