1. Field of the Invention
The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display and fabricating method thereof that can improve productivity and yield.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.
In the drawings:
FIG. 1 is a cross-sectional view illustrating a liquid crystal display of a color filter on thin film transistor structure according to the related art;
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
FIG. 2 is a cross-sectional view illustrating a liquid crystal display of a COT structure according to an embodiment of the present invention.
Referring to FIG. 2, the liquid crystal display of the COT structure according to an embodiment of the present invention includes a thin film transistor substrate (a lower plate) and a upper plate. The lower plate has a thin film transistor on a lower substrate 101; a color filter 134 for realizing R, G, B pixels formed on the thin film transistor and a black matrix 132; a pixel electrode 122 overlapped with the color filter 134 with an overcoat layer 152 therebetween; and the color filter having a lower alignment film 138 for aligning liquid crystal. On a upper substrate 102, the upper plate has a common electrode 124 which supplies a common voltage to the liquid crystal pixel cells; and a upper alignment film 136 for aligning liquid crystal.
