ABSTRACT:
The present invention provides an image forming method comprising the steps (1) to (5): (1) forming a first negative photosensitive resin layer on a substrate; (2) forming a barrier layer on the first negative photosensitive resin layer; (3) forming a second negative photosensitive resin layer on the barrier layer; (4) exposing the substrate, on which the first and second negative photosensitive resin layers are formed, to light via a photo mask having at least two types of light transmissible patterns; and (5) developing the exposed first and second negative photosensitive resin layers, wherein a photosensitivity ratio of the first negative photosensitive resin layer to the second negative photosensitive resin layer (the first/the second) is more than 1. The invention also provides a color filter, a spacer for a liquid crystal display device, and a projection for orientation control, each of which is formed by the method.
