Description of the Invention: [Technical Field] The present invention relates to a structure of a color filter, a method for fabricating the same, and an application thereof, and particularly to an effective reduction of parasitic capacitance between a data line and a color filter Color filter structure and its fabrication method. [Prior Art] A liquid crystal display is a passive display element in which a liquid crystal layer cannot actively emit light, so a light source is required to supply light and control the rotation of the liquid crystal to change the light transmittance to achieve different gray scale display. purpose. The problem with the liquid crystal display is that when the incident light of different angles is in the liquid crystal layer, the path lengths of the light rays of different angles traveling through the liquid crystal layer are different, and different phase and refraction are generated, so that the front view liquid crystal display and the front view When the liquid crystal display is viewed sideways, the light transmittance is not the same. Therefore, when the viewing angle is different, the light is deflected by a different number, and the _ penetration rate is not the same. Therefore, 'different perspectives will cause different degrees of light to display. When different color lights (such as red light, green light, and blue light) are mixed in different brightness ratios in front view and side view, color deviations that are different from those displayed in front view and side view are generated (c〇l〇). Rshif〇 phenomenon... In general, the degree of color deviation caused by side view is that the blue light is larger than the green light, and the green light is larger than the red light. Therefore, how to reduce the color deviation between the front view and the side view liquid crystal display is It is one of the topics that everyone is trying to solve. However, in order to solve the phenomenon of color deviation, it is divided into two sub-quality elements, and different gray levels are given to the two sub-pixels, so that the two The four-effect fire I5 white presented by the individual scorpion can reach the gray scale of the original sinus, and is close to the equivalent gray scale of the side view. For example, 'Please refer to Figure 1A, A liquid crystal display device of a low color deviation, comprising a liquid crystal cell 11 composed of a color light-emitting substrate, a liquid crystal layer and a thin film transistor substrate (not shown), the liquid crystal cell 11 Has a car arranged in the matrix P (i, j) 'its Shu = 1~m, j = 1~n; to ΡΟ ") as an example of its detailed structure, please see page 200 907 517 1B ®. As shown in Fig. 1B, the pixel P(1,1) is divided into a secondary sputum Pi and a secondary sputum _^2. _ wherein 'the secondary phenol p1 and the secondary phenol P2 respectively have a first thin film transistor T a thin film transistor 2 'the first thin film transistor Τι and the second thin film transistor din 2 Connected to a scan line S1 (1) and a scan line (1), the first thin film transistor D1, and the pole of the second thin film transistor 2 are coupled to a data line D (1), the thin film transistor The source of the T1 is connected to a first liquid crystal capacitor, and is coupled to a first storage capacitor Cst1, a source of the first thin film transistor 2, a second liquid crystal capacitor c, and a second storage capacitor Cst2, the first film. The transistor is the source and the source of the second thin film transistor 2, and the voltage A is read by a first pixel voltage Vp for a second pixel voltage V. It is: 'scanning, line S1 (1) and the scanning line S2 (1) for receiving a scanning signal transmitted by a gate driver 'the data line D_ to receive a data signal transmitted by the data driver. 'Refer to reference 1C' is the driving diagram I of the circuit in Fig. 1B in a frame>, at time b, at which time one of the transmissions transmitted by the scanning line Si(1) is reduced to a gate. The pole level Vgh is such that the first film transistor is turned on (ω "η 〇 n", and a lean signal is written by the lean line D (1) to the first liquid crystal capacitor - and the first storage capacitor Cst1. At a time b, one of the scanning signals transmitted by the scanning line is the gate low level Vgl, so that the first thin film transistor is blocked (tumor, scan line & (1) One of the transmission scan signals is a gate high level Vgh, so that the second thin film transistor is turned on, and the data signal is written into the second liquid crystal capacitor C|c2 and the second storage by the data line D(1). Capacitor Cst2., so that the two sub-stimuli have different transmittances during the kneading time', and the overall four-effect transmittance of the four elements is similar to the side view XI. This low color deviation The liquid crystal display device has two sub-pixels for each element, so in one screen time, the data line needs to be provided twice as much as the conventional liquid crystal display device. For example, a conventional liquid crystal display device having mxn pixels, in each side, the data driver needs to provide m data signals to each data line, but for a liquid crystal display device having a low color deviation of mxn pixels 'Only it has mxnx2 secondary sputum', so in each screen, data drive 6 200907517 actuator f provides mx2 data signals to each - data line. ° month and refer to Figure 2, which is the first 1B In the figure, along AA, the structure is etched into a color, and the structure is a substrate 彳. There are a plurality of 7 f ^^F^(ph〇toresist layer) 14, a photoresist layer 14 and a protective layer 16 on the black matrix 12. And the transparent electrode layer 18 which is covered with color. Under the money, the amount of data required to be touched by the 2m layer is twice as much as the data line 2〇 and the transparent electrode 18 are solid. Compared with the pixel structure that does not need to solve the chromatic aberration in the past, the load of the material 2 " the large load, and thus the work of the whole liquid crystal display is increased by β, and the present invention is directed to the above-mentioned missing structure. And its production method, the bloody bowl turns into a new shape and color light film [invention content] In order to effectively overcome the above problems.
