Summary:The invention provides a directional backlight display device with an eye tracking function. The directional backlight display device comprises a light source module, a reflective narrow-angle diffusion sheet, a backlight display panel, an eye tracking module and a tracking operation control module, the reflective narrow-angle diffusion sheet is provided with a rotating shaft; the reflective narrow-angle diffusion sheet reflects the light and forms a uniform directional light beam; the backlight type infrared image signal display panel is arranged on a projection light path of the uniform light directive light beam, and the uniform light directive light beam projects an image displayed by the backlight type display panel to a projection area. The tracking operation control module receives position information from the eye tracking module, forms an eye coordinate, calculates a correction projection area corresponding to the eye coordinate when the eye coordinate deviates, and controls a driving module to drive
