ABSTRACT:
An image forming method of the invention is an image forming method comprising the steps of exposing, through a photo mask, a substrate, on which a first negative photosensitive resin layer and second negative photosensitive resin layer are formed, wherein the photo mask is a photo mask having at least two light transmittable patterns, and the photosensitivity ratio of the first negative photosensitive resin layer to the second negative photosensitive resin layer is more than 1. This method makes it possible to form an image easily, which is used suitably by a reflection and transmission LCD display wherein the film thickness of a colored layer is partially varied in each pixel, and to easily form a spacer and a projection for orientation control.
