An object of the invention is to provide a plant information display device which deforms and displays drawing data without hiding all pieces of information necessary for plant monitoring and plant instrument operation while visibility is not lowered. The plant information display device according to an aspect of the invention includes an input unit; a region determination unit into which an interest region and a deformation condition in a plant are fed using the input unit, the region determination unit specifying a deformation target region based on the interest region and deformation condition supplied from the input unit; a region division unit which divides a drawing into plural regions based on the deformation target region specified by the region determination unit, the region division unit performing management while the deformation target region and a non-deformation target region are divided; a drawing distortion unit which separately deforms the deformation target region and non-deformation target region in a display region; a drawing output unit; and a display unit.
