Abstract
A liquid crystal element of a layered type capable of high contrast is provided.For example, in the liquid crystal element of the layered type including liquid crystal layers b, g and r in this order, each of the liquid crystal layers b, g and r is held between electrode formation surfaces of a pair of substrates each provided with an electrode, an insulating film is disposed between the electrodes of the substrates, and at least two liquid crystal layers of the liquid crystal layers b, g and r have the insulating films opposed to the liquid crystal layers and being different in refractive index from each other, respectively.
