Abstract
The present invention provides a manufacture method of a touch panel, comprising: step 1, forming a black matrix (2) on one side (11) of a color filter substrate (1); the black matrix (2) is positioned corresponding to a sensor pattern to be set to form gaps at portions of the black matrix (2) corresponding to the sensor pattern to be set; step 2, deposing a conductive film (3) on the other side (13) of the color filter substrate (1); step 3, coating photoresistor (4) on the conductive film (3); step 4, employing the black matrix (2) as a mask to implement exposure process and development process to the photoresistor (4) from the one side (11) of the color filter substrate (1) formed with the black matrix (2); step 5, implementing etching to the conductive film (3) by utilizing the photoresistor (4′) remained after the development to obtain the sensor pattern (3′) to be set; step 6, forming a protective layer (5) on the color filter substrate (1) and the sensor pattern (3′). The method saves manufacture times and the cost is low.
