A backlight is located on an incident side of a liquid crystal cell with a space. A first polarizing plate between the liquid crystal cell and the backlight is spaced from the liquid crystal cell. A second polarizing plate is located on an outgoing side of the liquid crystal cell. A light guiding plate is located between the liquid crystal cell and the first polarizing plate with a space from the liquid crystal cell to transmit a part of light and to guide the light to enter the liquid crystal cell. The display unit and the emitting unit are separately provided. The polarizing axes of the first polarizing plate and the second polarizing plate extend in different directions. When linearly polarized light after passing through the first polarizing plate enters the second polarizing plate, the second polarizing plate shuts off the linearly polarized light.
