The protective layer or its supporting substrate can simultaneously form an electrical isolation between the first electrode layer 141 and the second electrode layer 15A. Therefore, the liquid crystal display panel of the present embodiment can simplify the touch structure and reduce the overall thickness of the panel and the device to achieve a thinning effect. Referring to Figure 5, there is shown a cross-sectional view of a liquid crystal display panel in accordance with a second embodiment of the present invention.

Referring to Figure 6, there is shown a schematic cross-sectional view of a liquid crystal display panel in accordance with a third embodiment of the present invention. In the following, only the differences between the embodiment and the first embodiment 11 200933457 are explained, and the similarities are not described herein again. Compared with the first embodiment, the first electrode layer M11 of the first polarizing plate 140b of the third embodiment is formed on one side of the first dielectric layer 142, and is located on the first dielectric layer 142 and the polarizing film 144. The second electrode layer 15 is formed on one side of the first substrate 110 and is opposite to the liquid crystal layer 13 . Therefore, when the first polarizing plate 140b is assembled on the first substrate 11b, the second electrode layer M3 and the polarizing film ι44 are interposed between the first electrode layer and the second electrode layer 150b to form a Q touch structure. . Therefore, the liquid crystal display panel 100b of the third embodiment can have a touch function 'and reduce the overall thickness of the panel and its device. Referring to Figure 7, there is shown a cross-sectional view of a liquid crystal display panel in accordance with a fourth embodiment of the present invention. Only the differences between the present embodiment and the first embodiment will be described below, and the similarities are not described herein again. Compared with the first embodiment, the first electrode layer 141c of the first polarizing plate 14A of the fourth embodiment is formed on one side of the first dielectric layer 142, and is located on the first dielectric layer 142 and the polarizing film. Between 144, the second electrode layer 15〇c is formed on one side of the second ◎ dielectric layer 143 and between the second dielectric layer 143 and the polarizing film 144. Therefore, the polarizing film 144 is interposed between the first electrode layer 141c and the second electrode layer 15〇c to form a touch structure. Therefore, the liquid crystal display panel 100c of the fourth embodiment can have a touch function and reduce the overall thickness of the panel and its device. When the first polarizing plate 14Ac of the fourth embodiment is fabricated, the first electrode layer 141c and the second electrode layer 15cc may be previously formed on the first dielectric layer 142 and the second dielectric layer 143, respectively, and then The first dielectric layer 142 and the second dielectric layer 143 are further adhered to opposite sides of the polarizing film 144 by the adhesive material 1 ' 1 thus forming the first polarizing plate 14 〇 c. It can be seen from the above embodiments of the present invention that the liquid crystal display panel 12 200933457 of the present invention and its application on the display device can form a touch structure to achieve a touch function and can integrate at least one electrode layer in the polarizing plate to Simplify the touch structure and reduce the thickness of the panel and its device to achieve a thinner effect. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and retouched without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
