Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display structure, and more particularly to a liquid crystal display structure for improving light transmittance. [Prior Art] In the liquid crystal display technology, in order to achieve a rapid reaction and a wide viewing angle of liquid crystal molecules, it is necessary to cause liquid crystal molecules to exhibit different directions in a plurality of regions. Fig. 1 is a cross-sectional view showing a conventional liquid crystal display structure. The liquid crystal layer 5 is disposed between the thin film transistor (TFT) substrate 6 and the color filter (CF) substrate 9. The TFT substrate 6 includes a glass substrate 8, an electrode layer 2, and an alignment layer 3, wherein the electrode layer 2 is disposed on the glass substrate 8, and the alignment layer 3 is disposed on the electrode layer 2. The CF substrate 9 includes a glass substrate 7, an electrode layer 2, and an alignment layer 4, wherein the electrode layer 1 is disposed on the glass substrate 7, and the alignment layer 4 is disposed on the electrode layer 1. #Fig. 2 and Fig. 3 show the alignment directions of the alignment layers 3, 4, respectively. Fig. 4 shows the liquid crystal tilting direction of the liquid crystal molecules in the liquid crystal layer 5. Moxibustion According to Figure 2 and Figure 3, the alignment layer 3 has two alignment areas that are perpendicular to each other with an orientation of 18 degrees. The alignment layer 4 has two levels of difference! 8 〇 alignment direction of the alignment direction, which causes the liquid crystal molecules in the liquid crystal layer 5 to have an alignment effect of four regions (the solid arrows in FIG. 5 indicate that the liquid crystal molecules still have an alignment direction of the alignment layers 3 and 4). The other liquid crystals are tilted in between, that is, four liquid crystal pouring regions are caused. Fig. 5 shows a plan view of the electrode layer 1 and the electrode layer 2. Please refer to the 201211648 1 r 5 figure 'in the prior art', the alignment layers 3, 4 are used in combination with the electrode layer 1 and the electrode layer 2 without openings. However, in the process of applying a voltage to operate the liquid crystal display structure having the electrode layer 2, the alignment layer 3, 4, the alignment of the alignment layers 3, 4 causes cross-dark lines at the junction of the alignment regions, and further, the electrodes are received. The influence of the fringe field of layers i and 2, the edge of each alignment region also has boundary dark lines, as shown in Fig. 6, so the light transmittance of the liquid crystal display structure is low, for example, about 27.48. %. SUMMARY OF THE INVENTION The present invention provides a liquid crystal display structure which has less dark lines and a relatively high light transmittance. The invention proposes a liquid crystal display structure.
