PROBLEM TO BE SOLVED: To securely find a black-and-white inversion point defect which possibly becomes latent with time only through easy operation in the manufacturing stage of the liquid crystal display device. SOLUTION: For the inspecting method for inspecting whether or not pixels constituting the display surface V of the liquid crystal display device 17 equipped with an active element 13 have a defect, the entire display surface V is displayed with uniform lightness by controlling the illumination of each pixel by using a driver IC 18 and the display surface V is observed obliquely at an angleθ. Although a laser correction white dot and a black-and-white inversion defect can not be discriminated through an observation from the right- angled R direction, the both can be discriminated through the oblique observation.
