Abstract: A foreign substance inspecting apparatus of an LCD and an illumination controlling method thereof are provided to reduce a foreign substance of an LCD by enabling a sensor to sense decrease of illumination of a lamp and by enabling a feedback device to compensate for the illumination as a standard value. A foreign substance inspecting apparatus of an LCD comprises: a main body(209), a lamp(201) equipped in one portion of the main body, which irradiates light, a sensor(220) measuring illumination of light irradiated from the lamp, a light amount filter(203) controlling light amount irradiated from the lamp, a camera(205) photographing the light from the lamp and passed through an inspection sample and a feedback device(230) receiving the signal from the sensor and controlling light amount of the light amount filter and the lamp.
