The projection type display device includes a projection display unit that includes light sources, a light modulation element that spatially modulates light emitted from the light sources, and a projection unit that projects light spatially modulated by the light modulation element onto a projection surface; a sight line detection unit that detects a line of sight; and a system controller that stops projection of the projection light onto the projection surface by the projection display unit in a state where the line of sight detected by the sight line detection unit is out of the projection surface and restarts the projection of the projection light onto the projection surface by the projection display unit after a first time elapses after a timing of moment when the line of sight is determined to move from an outside of the projection surface to an inside of the projection surface.
