Abstract
A liquid crystal panel includes first and second substrates at least one of which has a light transmission property and which confront each other, first and second electrode layers which are formed on opposed faces of the first and second substrates, respectively, a polymer dispersion liquid crystal layer which is sandwiched between the first and second substrates, and a layer which is formed on at least one of the first and second electrode layers and has an uneven sectional shape so as to define concavities. At least liquid crystals disposed in the concavities of the layer are aligned in a predetermined direction.
