A color filter, comprising a substrate, a resinous black matrix and colored portions provided between elements of the resinous black matrix, wherein the colored portions are provided directly on the substrate and an angle formed between a side of each element of the resinous black matrix and the substrate is 70 to 88°.
A process for producing a black matrix, comprising the steps of:
- applying a black resist onto a substrate;
- subjecting the black resist to patterning exposure;
- developing the exposed black resist and subjecting the developed black resist to a rinsing treatment;
- wherein a pH value, a temperature and an ejection pressure of a developing solution used in the developing step are 10 to 12, 26° C. or lower and 3 MPa or lower, respectively, and a time interval between the termination of feed of the developing solution and the initiation of the rinsing treatment is 2 seconds or shorter.
A color filter, comprising a substrate, a resinous black matrix and colored portions provided between elements of the resinous black matrix, wherein an angle formed between a side of each element of the resinous black matrix and the substrate is 70 to 88°, and
- said colored portions are colored by applying ink between the elements of the resinous black matrix.
