A manufacturing method of a color filter including following steps is provided. First, a partition is formed on a substrate to form a plurality of pixel regions on the substrate. Next, a color pigment is provided along a continuous pigment-providing route, so as to form the color pigment on a sequence of pixel regions among the plurality of pixel regions and the partition. The method mentioned above can prevent the unfilled phenomenon of the pigment around the corners of the pixel region. Besides, a liquid crystal display panel having the color filter is also provided.

Liquid crystal display panel and color filter

A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.

A manufacturing method of a color filter comprising the following steps is provided. At first, a transparent substrate is provided. Next, a black matrix is formed on the transparent substrate to define a plurality of pixel areas on the transparent substrate. Then, an isolation layer is formed and patterned on the black matrix and then Red/Green/Blue color filter inks are filled into each of the pixel areas separately by inkjet printing.
