Abstract:
1. A liquid crystal display device, comprising: a liquid crystal cell including an upper substrate and a lower substrate, mutually facing and bonded to each other with a sealing member interposed therebetween, a liquid crystal layer encapsulated between the upper substrate and the lower substrate, a first conductor arranged on the inner surface side of the lower substrate; and a second conductor arranged on the inner surface side of the upper substrate; a reflective layer including a plurality of cholesteric liquid crystal layers, between the lower substrate and the first conductor, to reflect at least a portion of elliptically polarized light having a predetermined rotation direction, the plurality of cholesteric liquid crystal layers being laminated on top of each other, at least one of the plurality of cholesteric liquid crystal layers having a different helical pitch from the others in order to reflect white light; an upper-substrate side elliptically-polarized-light input device to cause elliptically polarized light to enter the liquid crystal layer from the upper substrate side, the liquid crystal layer reversing the component of elliptically polarized light that is incident during one of a selection electric field applied state and a non-selection electric field applied state, and not changing the component of the elliptically polarized light during the other of the selection electric field applied state and the non-selection electric field applied state; and an IC mounted on the inner surface side of the upper substrate outside the sealing member, the IC being electrically connected to the second conductor, while being electrically connected to the first conductor through an inter-substrate conductor.
