Embodiment Construction

[0050] Some embodiments of the present invention are described in detail as follows. However, the invention may also be practiced broadly in other embodiments than those described in detail, and the scope of the invention should not be limited except by the appended claims.

[0051] For a first embodiment of the present invention see figure 1 Plan view of color liquid crystal display and figure 2 A cross-sectional view of a color liquid crystal display. Figure 3A, B is a schematic diagram of the process. In this embodiment, the surface of the glass substrate on which components such as scanning lines and signal lines are arranged is called the front side, and the other side on which the above-mentioned components are not arranged is called the back side. First, a thin film transistor 13 (TFT: Thin Film Transistor) is formed on the glass substrate 20 , and the thin film transistor 13 can be manufactured by using a common semiconductor process method. Next, form an interla...

Abstract

The invention discloses a color optical filter making method, depending on the method to form photoresist or insulating space substance in non-pixel region, and avoiding the color relative permeation and mix phenomenon of other adjacent colorizing materials, so as to make the color optical filter with good color reappearance and color resolution. It includes: forming an interbedded insulating layer on a basal plate; forming many scanning lines and many signal lines on the interbedded insulating layer to define many pixel regions and a non-pixel region; forming a photoresist or insulating layer on the interbedded insulating layer; composing a picture of the photoresist or insulating layer to form photoresist or insulating space substance in the non-pixel region; and using spray-ink method to project a colorizing material in many pixel regions.

Description

technical field [0001] The invention relates to a method for manufacturing a color filter, in particular to a method for manufacturing a color filter by an inkjet method. Background technique [0002] Generally speaking, the main components of a liquid crystal display device are two electrode substrates each having a pixel formed by electrodes facing each other and arranged opposite to each other under a gap, and the edges of the gap are sealed to sandwich the liquid crystal layer. constitute. [0003] In liquid crystal display devices, especially liquid crystal display devices capable of displaying arbitrary color image frames, color filters are generally used. The color filter has three primary colors of R, G, and B (red, green, and blue) on any one of the two electrode substrates, or an arrangement of colorable multicolor hue dyeing elements corresponding to each pixel. [0004] Among the manufacturing methods of color filters, there are pigment dispersion methods in wh...
