In a method for manufacturing a reflector having a plurality of convex portions 4 that are obtained by means of melt deformation of column-shaped bodys 15 formed of a photosensitive resin material, the photosensitive resin material has aspect ratio vs. average tilt angle characteristics in which an average tilt angle θ reaches a maximum value through an incremental change process and then converges to a certain value through a decremental process when an aspect ratio is gradually increased from a value close to zero, provided that the average tilt angle of the convex portion is an angle of elevation from the outer periphery of the bottom surface of the convex portion 4 to an apex of the convex portion and that the aspect ratio is a ratio of the height of said column-shaped body 15 with respect to the width thereof. A set value for the aspect ratio of the column-shaped body 15 that is obtained after the development step is determined to be a larger aspect ratio than a starting point from which convergence to said certain value begins. This configuration provides a reflector having good contrast characteristics and PAPER WHITE APPEARANCE, and a reflective liquid crystal display panel that uses the above-mentioned reflector.
