Liquid crystal display device and method for manufacturing the same

A liquid crystal display device, comprising:

• a transparent insulation substrate;
• a black matrix and a color filter layer formed on the substrate in that order;
• an indium tin oxide (ITO) or overcoating layer formed on the color filter layer;
• a pattern of post spacers formed on the ITO or overcoating layer;
• and
• a liquid crystal layer formed on the substrate.

A method for manufacturing a liquid crystal display device, comprising the steps of:

• preparing a transparent insulation substrate;
• forming a plurality of black matrixes on the substrate and then forming a plurality of color filter layers flush with and between the black matrixes;
• forming a pattern of post spacers on the black matrixes and the color filter layers;
• and
• forming a liquid crystal layer on the substrate by means of polymer dispersed liquid crystal.
