Description of the Invention: [Technical Field] The present invention relates to a display panel, and more particularly to a liquid crystal display panel. [Prior Art] Liquid Crystal Display (LCD) is widely used in a wide variety of electronic products due to its low power consumption, low heat generation, light weight, and non-light absorbing properties. Gradually replace the traditional cathode ray tube display (CRT Display). For liquid crystal display devices, there are many technical requirements to judge the quality of the products. Among them, as the needs of users become higher and higher, the wide viewing angle has become one of the indispensable technical requirements. At present, there are many wide viewing angle technologies used in the industry, one of which is Multi-Domain Vertical Alignment (M VA) technology. As the name suggests, liquid crystal display panels using multi-region vertical alignment technology, the liquid crystal molecules are perpendicular to the panel when not energized. When energized, the liquid crystal molecules are inverted in different directions, so that the screen can be obtained from different angles. Compensation, which in turn increases the viewing angle. Please refer to FIG. 1 , which is a simple schematic diagram of a multi-region vertical alignment technique. The liquid crystal display panel 1 has a color filter, an optical substrate 11, and a thin film transistor substrate 12. The color filter substrate 11 has a common electrode 111. The thin film transistor substrate 12 has a halogen electrode 121, and a liquid crystal layer 13 is disposed between the common electrode 111 and the halogen electrode 121. Many liquid crystal molecules 131. Further, in the multi-region vertical alignment technique, the thin film transistor substrate 12 further has a plurality of protrusions 122. For the multi-zone vertical alignment technique, the liquid crystal molecules ΐ3ΐ are not energized, and their long axis is perpendicular to the surface of the color light-transmissive layer and the thin film transistor substrate 12. Only the liquid crystal molecules i3i in the vicinity of the protrusions 122 are slightly inclined and have a pretilt angle (Pre_TiuAngie) due to the side field effect (5) of the protrusions 122. Only then can the light not penetrate the liquid crystal display panel i and the black display appears. Referring to Fig. 2, after the energization, the liquid crystal two sub-131 near the protrusion 122 has a pretilt angle, so that the liquid crystal molecules 131 farther from the protrusion m can be quickly tilted to an appropriate inclination angle. At this time, the light can penetrate the liquid crystal display 7TT panel 1 and can be modulated by light. Further, since the long axes of the liquid crystal molecules 131 in different regions are directed in different directions, they can have an optical compensation effect and achieve a wide viewing angle. In addition, since the liquid crystal molecules 131 already have a pretilt angle when they are not energized, the liquid crystal molecules 131 are relatively rotated to a predetermined position after being energized, so that the multi-region vertical alignment technique is also advantageous for the liquid crystal molecules. Response speed, and shorten and reaction time. ~ Of course, in the multi-zone area vertical alignment technique, in addition to the shape of the protrusions 122, a side field effect can be generated, and other shapes can be used to generate the edge % effect, thereby achieving a wide viewing angle. Referring to FIG. 3, two conventional liquid crystal display panels 2 using a multi-region vertical alignment technique include a color filter substrate 21 and a thin film transistor substrate 22. The color filter substrate 21 has a common electrode 211, and the thin film transistor substrate 22 has a halogen electrode 221 filled with liquid crystal molecules 231 between the pixel electrode 221 and the common electrode 211. Further, the halogen electrode 221 has an electrode pattern, the electrode pattern has at least one main electrode 2211 and a plurality of secondary electrodes 2212, and the secondary electrode 2212 is provided on both sides of the main electrode 2211 and spaced apart. A slit 2213 can be considered to exist between the two secondary electrodes 2212. Due to the side field effect produced by the shapes of the main electrode 2211, the sub-electrode 2212 and the slit 2213, the liquid crystal molecules 231 can be reversed in different directions after being energized, thereby achieving a wide viewing angle. For the electrode pattern described above, the liquid crystal molecules are tilted from the direction along the sub-electrode 2212 (or the slit 2213) toward the central portion of the electrode pattern. Therefore, if the distance between the secondary electrode 2212 (or the slit 2213) of the halogen electrode 221 is too long, the liquid crystal molecules 231 which are far away from the central portion cannot completely drive the liquid crystal molecules 231 which are closer to the central portion to rotate until the current is turned on. The predetermined location, causing some Sub Domains to appear. Referring to FIG. 4A to FIG. 4D, the liquid crystal display panel 2 of FIG. 3 sequentially passes through the photographs of the liquid crystal molecules at 8 milliseconds, 16 milliseconds, 24 milliseconds, and steady state after being energized. Among them, Fig. 4D shows steady state. In Fig. 4D, it can be clearly seen that the liquid crystal display panel 2 generates four sub-regions D21, 〜1D24 and two distinct boundary boundaries L21, L22, and at the boundary lines L21, L22, the liquid crystal molecules are not The light is transmitted, thereby reducing the light transmittance of the entire liquid crystal display panel 2. As can be seen from Figs. 4A to 4D, the liquid crystal molecules 231 cannot reach the steady state very quickly, so that the reaction time is increased between 200912451. The above two defects are very disadvantageous to the liquid crystal display panel 2. Therefore, how to provide a liquid crystal display panel capable of solving the above problems and having the characteristics of wide viewing angle, high transmittance, and high reaction speed has become one of the urgent problems to be solved. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a liquid crystal display panel which can have a wide viewing angle, a high transmittance, and a high reaction speed. For the above purpose, a liquid crystal display panel according to the present invention comprises a first substrate, a second substrate and a liquid crystal layer.

The second substrate is opposite to the first substrate and has a pixel electrode, and the halogen electrode is opposite to the common electrode and has at least one electrode pattern, and the electrode pattern has at least one main electrode and a plurality of secondary electrodes. The equal-order electrode systems are disposed on both sides of the main electrode and are spaced apart. The sub-slit extending directions of the first substrate are parallel to the sub-electrode extending directions of the second substrate.

Therefore, after energization, the liquid crystal molecules located in the central portion of the sub-halogen structure can be simultaneously driven by the liquid crystal molecules in the vicinity of the electrode pattern and the liquid crystal molecules in the vicinity of the slit pattern, and rapidly tilted to a desired angle, thereby making the liquid crystal The molecules reach the point of resilience quickly and reduce the cost of the boundary of the sub-region, thereby increasing the penetration rate and achieving a wide viewing angle.
