This device for inspecting surfaces by deflectometry comprises: a display device (2) designed to generate, on its face called the front face, a pattern of alternate light and dark fringes; at least one sensor (3) designed to acquire the image reflected by the surface to be inspected (5) positioned on the front face of the display device and at the periphery of the latter; and a reflecting means positioned in relation to the surface to be inspected (5) so as to direct the image reflected by the surface to be inspected (5) toward the sensor (3), the display device being oriented in relation to the surface to be inspected at an angle such that the display device is viewed by the sensor at normal incidence.
