Abstract
There is such an issue with the well-known optical element that it is difficult to achieve a high transmittance since the transmittance is determined according to the pattern size of the light transmission regions, so that the luminance of the display device to which such optical element is mounted is deteriorated. Provided is an optical element which employs a structure in which the shape of a conductive pattern where electrophoretic particles cohere in a wide viewing field mode is formed in a comb-like shape and plural stages and plural rows of light transmission regions are disposed in the spaces between the comb teeth. This makes it possible to exclude the electrophoretic particles from the regions other than the comb-like electrode for allowing the light to transmit that part.
