Color filter substrate and method for fabricating the same

A method of fabricating a color filter substrate, comprising the steps of:

• forming a plurality of color filters on a substrate, the plurality of color filters are spaced apart from each other by a first interval;
• forming a common electrode on an entire surface of the substrate to cover the plurality of color filters;
• forming a photosensitive black material layer on an entire surface of the common electrode to substantially fill the first intervals between the plurality of color filters;
• providing a mask over the photosensitive black material layer, the mask has a plurality of light-transmitting portions and light-shielding portions;
• applying light to the photosensitive black material layer from an upper side of the substrate through the mask;
• applying light to the photosensitive black material layer from a lower side of the substrate;
• developing the light-applied photosensitive black material layer to form a plurality of black matrix portions within the first intervals between the plurality of color filters and to form a plurality of spacers above the color filters;
• and
• forming an orientation film over the entire surface of the substrate to cover the plurality of spacers, the plurality of black matrix portions and exposed portions of the common electrode.
