Abstract: According to one embodiment, an electronic apparatus includes a camera, a first polarizer, a second polarizer, a liquid crystal panel, and a controller controlling the liquid crystal panel. The liquid crystal panel includes a first region and a second region. The controller controls a first opening mode of transmitting light through the first region and the second region, and a second opening mode of making a quantity of light transmitted through the first region smaller than a quantity of light transmitted through the second region.
