Field of the Invention The present invention relates to a color filter, and more particularly to a color filter suitable for use in an inkjet process. Soil 5 [Prior Art] With the growing demand for liquid crystal displays, the demand for color filters has also increased with the increase of the number of colors. Therefore, reducing the manufacturing cost of color filters has become an urgent task. 10 Design of color filters High color purity, high transparency, high contrast, etc. are required. There are four conventional color filter coating methods, namely Dyeing, Pigment Dispersion, and Electro-deposition (Electro- Deposition), as well as printing. However, these methods are not only complicated in process, expensive in process equipment, but also limited in size of 15 color filters. In addition, when the process and size increase, the color filter yield is limited. In order to solve the conventional problem of the color-passing film process, the ink-jet method (Ink-Jet) has been developed in recent years. The ink-jet method has many superior features, such as the use of small equipment, Reducing process time and reducing ink consumption. However, during the production of color filters by inkjet method, the color ink droplets are injected into the black matrix. District ⑽-pixel) won the day easily drops due to the high diffusion capacity color ink, ink overflow phenomenon occurred, resulting in color mixing and color distribution are not 'affect the color and contrast, namely the phenomenon of color cast. 200914895 In order to eliminate the phenomenon of color cast, the conventional method is to form a retaining wall to deepen the area of the alizarin to accommodate the ink imitation 耘袅 & a 1^ work room to prevent black & overflow. However, this practice is not only complicated, but also prevents
