摘要： Disclosed are a liquid crystal display device capable of obtaining preferable display images, whose manufacturing cost is low, and which does not deteriorate the environment at the time of fabrication and a method for fabricating the same. According to the invention, there is provided a liquid crystal display device comprising: a first substrate on which a black matrix, a color filter, and a counter electrode are formed; a second substrate on which a plurality of gate signal lines and a plurality of source signal lines which are disposed so as to cross each other via a gate insulating film, thin film transistors disposed in intersecting points of the gate signal lines and the source signal lines, and pixel electrodes in a matrix disposed in the areas surrounded by the gate signal lines and the source signal lines are formed; and a liquid crystal layer provided between the first substrate and the second substrate, wherein the black matrix is formed by a black resin optical shielding layer and a blue filter layer. In a method for fabricating the liquid crystal display device according to the invention, the black matrix part formed by the blue filter layer is constructed by a photoresist film in which a blue pigment is dispersed and the photoresist film is patterned by using back side exposure.
