To provide a reflective liquid crystal display element wherein a stage for forming the ruggedness to be a base of a reflection plate on a substrate is simplified and further more light reflection is suppressed to give satisfactory light scattering properties to the display element and to provide a manufacturing method for the liquid crystal display element.

The manufacturing method includes a stage for applying at least one layer of a photosensitive resin film 3 on the surface of one substrate 1 of substrates opposed to each other, a stage for forming a number of continuous rugged parts 13' on the surface of the photosensitive resin film by changing the state of the photosensitive resin film 3 from the atmospheric pressure to a reduced pressure state and evaporating dissolved gas and a solvent in the photosensitive resin film to form bubbles and a stage for forming a reflection film 4 on the photosensitive resin film 3 having the rugged parts 13'. A heat treatment stage for rounding the square of the rugged parts 13' is added after the rugged pars 13' is formed on the surface of the photosensitive resin film. Therefore, the rugged shapes can be formed in one photolithography stage, the reflection of a light source is suppressed and the reflection plate having the light scattering properties can be formed.
