An electrooptic device includes: a display panel for displaying images; an illumination system for applying light to the display panel; a polarizing-axis control unit disposed between the illuminating system and the display panel, the control unit allowing light having a first polarizing axis of the light emitted from the illuminating system to pass through, and changing part of the light from the illuminating system into light with a second polarizing axis that is substantially orthogonal to the first polarizing axis; a lens disposed between the polarizing-axis control unit and the display panel, the lens including a plurality of linear lens patterns directing the light with the first polarizing axis and the light with the second polarizing axis separated by the polarizing-axis control unit into specified directions; a first polarizing unit disposed between the illumination system and the lens; and a second polarizing unit disposed between the display panel and the lens. Both the polarizing axis of the first polarizing unit and the polarizing axis of the second polarizing unit are substantially parallel to or perpendicular to the extension of the lens patterns.
