Measuring Method for Width of Color Filter Unit and Manufacturing Method for Liquid Crystal Panel

A manufacturing method of a liquid crystal panel, for integrating a color filter plate onto a thin film transistor (TFT) array substrate, the method comprising:

• forming a TFT array on a glass substrate;
• forming the color filter plate locating within an effective region of the liquid crystal panel by photo-etching process, and forming one or more measure modules locating of the liquid crystal panel and on the TFT array by the photo-etching process, wherein the color filter plate comprises a red filter unit, a green filter unit and a blue filter unit, and widths of the one or more measure modules and the color filter units are identical;
• measuring widths of the one or more measure modules out of the effective region to obtain the width of the filter units within the effective region;
• and
• removing the measure module out of the effective region to form the color filter plate within the effective region.
