A pattern forming body is provided or a color filter, wherein the color
filter can be manufactured efficiently by a simple process without any
cracks and no influence to an alignment of a liquid crystal. A pattern
forming body is provided comprising: a base material; a photocatalyst
containing layer, comprising at least a photocatalyst, formed on the base
material; a protecting part formed on the photocatalyst containing layer;
a property variable layer, whose surface property is varied by a function
of a photocatalyst due to an energy irradiation, formed so as to cover
the photocatalyst containing layer and the protecting part; and a
property-varied pattern which is a property varied property variable
layer.
