Description of the Invention: [Technical Field] The present invention relates to a touch panel and a liquid crystal display panel, and more particularly to a touch function having a filter function Panel and colorful LCD panel with touch function. [Prior Art] • In today's information society, human dependence on electronic products has gradually increased. Electronic products such as mobile ph〇ne, handheld pc personal digital assistant (p(10) nalDigitalAssistance, pDA) or smart phone can be seen everywhere in life. In order to allow the user to have a larger visual interface and provide a more convenient operation mode in a limited volume, some electronic products combine the touch panel with the display panel to form a color touch display panel. FIG. 1 illustrates a conventional color touch display panel. Referring to FIG. 1, the color touch display panel 1A includes a display panel HQ and a touch panel 120'. The touch panel 120 is attached to the display panel 110 by a double-sided tape 13A. The display panel 110 is, for example, a display panel of a flat panel display such as a liquid crystal display (LCD) or an organic light emitting display (OLED) that can perform colorful display. Meanwhile, the touch panel 120 is a digital capacitive touch panel including a plurality of strip-shaped upper electrodes 122, a plurality of strip-shaped lower electrodes 124, and a dielectric layer U6 sandwiched between the upper electrodes 122 and the lower electrodes 124. . When the touch panel 120 is attached to the display panel ι1 by the double-sided tape 130, the color touch panel 5 WP9602-C400-0606 23926twf.doc/n the control panel 100 has the functions of touch and colorful display. . However, the double-sided tape 130 is attached only to the periphery of the display panel 11A and the touch panel 12A, so that a gap G exists between the touch panel 120 and the display panel 100. When the light passes through the gap G, the light leakage of the panel 100 or the decrease in the light transmittance may be caused by the difference in the refractive index between the media, so that the quality is deteriorated. In addition, the combination of the touch panel 12A and the display panel 1〇〇 makes the thickness of the color touch display panel (10) unreducible, and cannot meet the demand for thin electronic devices on the market. In addition, FIG. 2 illustrates another color touch display panel of the prior art. Referring to FIG. 2, the color touch display panel 2 is substantially the same as the color touch display panel 100. The difference is that in the color touch display panel 200, the touch panel 12 is made of optical glue. 23〇 is attached to the display panel 110. The optical adhesive 230 is integrally applied between the display panel n〇 and the touch panel 120. Therefore, the color touch display panel 2 is less prone to light leakage and has a good display effect. Unfortunately, the cost of the optical adhesive 230 is relatively high and the thickness of the color touch display panel 2 is still not reduced. At the same time, the optical adhesive 230 may cause a problem of poor reliability after a long period of use. It can be seen that the conventional color touch display surface can not meet the development trend of thinning electronic products and the display quality of the touch display panel. SUMMARY OF THE INVENTION The present invention provides a touch panel having a filtering and optical function to solve the problem that the touch panel in the color touch display panel needs to be additionally attached to the color display surface 1358659 WP9602-C400-0606 23926twf.doc/ n The arrangement direction of the strip electrode patterns is substantially perpendicular.
