As the main component of TFT-LCD, liquid crystal panel can be divided into thin film transistor array substrate and color filter substrate according to its structure. It is easy to leak light, the aperture ratio is reduced, and the brightness of the panel is reduced. At the same time, the application on the curved display is limited.
[0003] In order to solve the problems of light leakage and panel brightness reduction caused by inaccurate alignment, there is a color filter integrated on the array substrate (Color Filter on Array, COA) combined with a black matrix integrated on the array substrate (Blackmatrix on Array, BOA) technology, the color filter Partially integrated on the array substrate, that is, the color photoresist layer and black matrix are prepared on the array substrate, which overcomes the unfavorable factors caused by poor alignment, but this technology of COA combined with BOA still does not reduce the production process, resulting in cost did not improve

Abstract
The invention discloses a manufacturing method for a display panel based on a BOA technique. The manufacturing method comprises the following steps: providing an array substrate, wherein the array substrate comprises a display area and a non-display area; forming a colorful light resistance layer and a black matrix layer on the array substrate; forming spacers in the process that the colorful light resistance layer and / or the black matrix layer are formed. The invention further discloses a display panel based on the BOA technique. By adopting the mode, the spaces can be formed while the colorful light resistance layer and / or the black matrix layer are formed, so that the procedure of independently manufacturing the spaces can be reduced, the manufacturing process of the whole display panel can be shortened, and the production cost can be lowered.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel based on BOA technology and a manufacturing method. Background technique [0002] Thin film transistorliquid crystal display (thin film transistor-liquid crystal display, TFT-LCD) is widely used in the current flat panel display industry due to its characteristics of lightness, thinness, and small size, low power consumption, no radiation, and relatively low manufacturing cost. As the main component of TFT-LCD, liquid crystal panel can be divided into thin film transistor array substrate and color filter substrate according to its structure. It is easy to leak light, reduce the aperture ratio, and reduce the brightness of the panel. At the same time, its application on curved displays is limited. [0003] In order to solve the problems of light leakage and panel brightness reduction caused by inaccurate alignment, there is a color filter integrated on the array...
