An LCD panel with mixed substrate materials and a method of making the LCD panel are presented. The LCD panel is made of a first substrate, a second substrate disposed substantially parallel to the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes a glass substrate, a TFT formed on the glass substrate, and a color filter formed on the TFT. The second substrate includes a plastic substrate and a common electrode formed on the plastic substrate. Forming the color filter on the TFT eliminates the need to form black matrices on the second substrate, preventing misalignment of the two substrates due to different heat sensitivities. Since there is no concern of substrate misalignment caused by heat, laser beam can be used to cut the substrates during the manufacture of the LCD panel.

1. Field of the Invention
The present invention relates to a liquid crystal display panel, and more particularly to a method of cutting the substrates of a liquid crystal display panel.
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.
FIG. 1 is a perspective view of an LCD panel according to a first embodiment of the present invention;
FIG. 2 is a sectional view, taken along the line II-II of FIG. 1;
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings wherein like reference numerals refer to like elements throughout. The embodiments are described below so as to explain the present invention by referring to the figures.
An LCD panel 1 includes a first substrate 100 on which TFTs (T) are formed, a second substrate 200 disposed opposite the first substrate 100 and on which a common electrode 221 is formed, a sealant 300 coupling the two substrates 100, 200, and a liquid crystal layer 400 disposed between the substrates 100, 200 and contained by the sealant 300. The substrates 100, 200 have a rectangular shape, and the first substrate 100 is bigger than the second substrate 200. The first substrate 100 has an overlapping area where it overlaps the second substrate 200 and a pad area that extends beyond the second substrate 200. The TFT (T) and the sealant 300 are formed in the overlapping area, and a gate pad 123 and a data pad 144 are formed in the pad area to connect with an external circuit. The pad area is formed along two connected sides of the rectangularly-shaped first substrate 100.
The first substrate 100 will now be described. The description will focus on the gate pad 123. The data pad 144 is not separately described because it is similar to the gate pad 123.
