The utility model relates to the technical field of liquid chromatograph detection, in particular to a liquid chromatograph diode array detector which comprises a grating, a linear array image sensor and a cylindrical mirror. The cylindrical mirror is positioned between the grating and the linear array image sensor and is positioned on a light emitting path of the grating; the cylindrical mirror is provided with a light inlet face facing the grating and a light outlet face facing the linear array image sensor, the cylindrical mirror is provided with an image height section intersecting with the length direction of the cylindrical mirror in the direction from the light inlet face to the light outlet face, and the intersecting line of the image height section and the light inlet face is not parallel to the intersecting line of the image height section and the light outlet face. And the cylindrical mirror is used for matching the imaging height with the height of the detection surface of the linear array image s
