PROBLEM TO BE SOLVED: To provide an inspection device of a liquid crystal panel capable of preventing an inspection omission. SOLUTION: In the liquid crystal panel 11, color filters in three colors of R, G and B for filtering light radiated from a backlight are installed. The inspection device 30 for inspecting the liquid crystal panel 11 includes a camera 31 for imaging the liquid crystal panel 11, and outputting its light reception signal; a backlight 32 for inspection for irradiating the liquid crystal panel 11 with light from the opposite side to the camera 31; a color filter 35 for correction interposed between the liquid crystal panel 11 and the camera 31, for filtering so that each light can be detected as light having the same intensity by the camera 31 when each light in each color transmitted through each color filter of the liquid crystal panel 11 has the same light quantity; and an operation processing part 33 for comparing a detection value acquired based on the light receiving signal outputted from the camera 31 with a prescribed inspection reference value, and detecting as a defect when exceeding the inspection reference value.
