Abstract
A liquid crystal device in which a horizontal electric field is applied to a liquid crystal layer of a transflective type. Spacers are disposed to set a distance between substrates and to prevent deterioration of display quality by eliminating thickness non-uniformity of an alignment layer due to the presence of a retardation layer. Slits are provided in the retardation layer regions to prevent deterioration of display quality by preventing dissolution and flow of an ingredient of the retardation layer to the liquid crystal layer side through the alignment layers.
