In a touch panel manufacturing method, a substrate is prepared, a sensing layer and a protective layer are sequentially formed on the substrate, an electrode layer with spaced electrodes is formed by firing, and the electrode layer is penetrated through the protective layer and formed on a surface of the sensing layer. Since the sensing layer is covered by the protective layer before forming the electrode layer, the sensing layer can be avoided to be influenced by accompanying heat, chemical substances and/or oxygen gas, its intrinsic physical characteristics are retained and its periphery would not be damaged. Moreover, since the formation of the protective layer is prior to the electrode layer, the height difference formed at the periphery of the electrode layer and the optical interference phenomena both are prevented. Finally, the manufacturing process is simplified and thus production speed and production capacity are increased.

The invention relates to the field of display processing, in particular to a color film substrate and a preparation method thereof and a display panel and a display. The color film comprises a lining substrate, black matrices, pixel units, a conducting layer. The black matrices are overlaid on the lining substrate to form black matrix graphic patterns. Pixel grooves are formed at the positions corresponding to the opening positions of the black matrix graphic patterns, of the lining substrate. The openings of the corresponding pixel grooves and black matrix graphic patterns are filled by the pixel units and the pixel grooves on a one-to-one mode. The upper surface of the pixel units is in parallel with the upper surface of the black matrices. The conducting layer is overlaid on the surface of the black matrices and the surface of the pixel units. The color substrate can avoid the problem of light leakage caused by the elevation difference between the black matrices and pixel units, can avoid the angle section difference caused by the forming of overlap area, and therefore is beneficial to the optimization of the display effect of the display panel containing the color film substrate.
