Abstract

According to one embodiment, an optical control device includes a first liquid crystal cell and a second liquid crystal cell. The second liquid crystal cell is stacked on the first liquid crystal cell. The first liquid crystal cell has a function of modulating and converting a first polarization component of incident light into a second polarization component, and hardly modulating and converting a third polarization component of incident light into a fourth polarization component. The second liquid crystal cell has a function of hardly modulating the second polarization component transmitted through the first liquid crystal cell, and modulating the fourth polarization component transmitted through the first liquid crystal cell.
