Description

201102726 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a display, in particular, a reflective or transflective liquid crystal display having a high aperture ratio and a high contrast ratio. [Previous technology] With the advancement of science and technology, the liquid crystal display with many advantages such as power saving, no radiation, small size, low power consumption, ♦ plane right angle, high resolution, and stable quality is the original exclusive position. Traditional image tube (CRT) has brought great impact. Especially, today's various information products such as mobile phones, notebook computers, digital cameras, PDAs, LCD screens and other products are becoming more and more popular, and LCDs are also popular. The demand for this has been greatly increased. A liquid crystal display device can be classified into a transmissive type, a reflective type, and a transflective type according to its light source mechanism. For the money, the penetrating liquid department is provided by the county module with the problem of excessively large consumption and too strong Weiguang (such as sunlight). Reflective liquid crystal display replaces the transparent electrode layer with the reflective electrode layer. The light source is mainly used to provide the light source. Therefore, it is not necessary to use the backlight module, the light source is applied to the outdoor large-scale liquid crystal display board or the portable electronic device is added. The resolution of the outdoor product, etc., but due to the uneven brightness of the sister's light, the lack of reflection is insufficient. Therefore, it does not work when the ambient light is insufficient. In order to avoid the shortcomings of the above two types of liquid crystal displays, and to make full use of their advantages, the transflective and transversal half-through devices have become one of the most advanced liquid crystal display technologies. In addition, in order to pick the surface crystal display || the overall application is fine, the display technology of the liquid crystal display 201102726 is continuously invested in research and development to improve. Among them, for the same liquid crystal molecule arrangement state 'effective optical path at different viewing angles In terms of temperament, the industry is eager to develop a wide viewing angle technology. For example, the MVA (Multi-Domain Vertical Alignment) technology developed by Shitong can simultaneously improve the upper and lower viewing angles to about 120 degrees. Since the wide viewing angle technology has been continuously improved' and actually incorporated into the production line, this has made the LCD display's improvement in viewing angle not inferior to the traditional CRT. In the current development of liquid crystal display technology, with double gap (duai笆叩For example, a semi-transflective MVA liquid crystal display with a double gap is usually provided with an adjustment layer 121 in the reflection region R as shown in FIG. 1A. Color filter (colorfllter; CF) substrate side

Or a thin film transister (TFT) substrate side. The 1A and IB diagrams respectively show the above view and cross-sectional view of the MVA technology applied to the double-gap transflective liquid crystal display. As shown in Fig. 1A, the basic structure of the double-gap transflective MVA liquid crystal display comprises an array substrate 丨丨, a color 泸, a light substrate 12, and a liquid crystal layer 13. The array substrate η has a plurality of sub-quartine regions 110, and each of the sub-quartz regions 100 is provided with a reflection zone and a penetration zone Τ. The color furnace substrate 12 also has a plurality of sub-quartel regions 120 corresponding to the plurality of sub-pixel regions 110 of the array substrate, and each of the sub-pixel regions 120 is in a row. An adjustment layer 121 is disposed at each of the area and the corresponding location. The liquid crystal layer 13 is disposed between the array substrate 丨丨 and the color filter and the optical sheet substrate 12. Please refer to FIG. 1 again, in the sub-dielectric region η of the array substrate η, there is a thin film transistor (TFT) and a storage capacitor (1) in the reflective region R. Below. Then, "= layer 201102726 112 is formed on the upper surface of the array substrate U. Then, on the flat layer η, the surface of the concave and convex is made in the opposite (four) R, and the metal with high reflectivity (for example: Ming 'silver...etc.) is used as the reflection » 113, and each sub-diet region 11 The penetrating regions T are also provided with a transparent electrode 114. It is worth mentioning that there is a contact hole 115 in the reflective region R of each of the pixel regions 110 of the array substrate 11 for electrically connecting the reflective electrode 113 and the storage capacitor lu. In addition, the color filter substrate 12 is further provided with an alignment protrusion (PR) for the position of the reflection region R and the penetration region τ of the array substrate. Since the alignment protrusions 122 change the distribution of the power lines, the liquid crystal molecules are tilted in the direction of the alignment protrusions 122 to produce the effect of the multi-region liquid crystal alignment (?1111_(^〇1111)). The technique of viewing angle, and the problem of gray scale inversion in the single-domain liquid crystal alignment. As shown in Fig. iB, the color filter is usually used when the array substrate 11 and the color filter substrate 12 are assembled. The light substrate 12 is further provided with a spacer (125) for fixing the cell gap, and a plurality of platforms 116 corresponding to the spacers 123 are designed on the array substrate side η to make the spacers 123 can maintain the panel spacing more stably. However, please refer to FIG. 1B, because the liquid crystal molecules in the vicinity of the edge of the adjustment layer 121 and the spacer 123 are affected by the height difference, and the liquid crystal molecules are arranged at an angle. The dark state leakage causes the penetration contrast to decrease. The liquid crystal molecules in the contact hole 115 are also poorly arranged due to the influence of the concave topography, and the problem of reflecting the dark state light leakage is also caused. The contrast of the shot is lowered, and the contact hole 115 does not contribute to the reflectance, so the contact hole also causes the aperture ratio to decrease. Also, due to the dark light leakage problem of the spacer 123, it can be understood that the design position of the spacer 123 must be quite cautious. Metropolitan 201102726, the spacers 123 are designed to be flat (four), and the side coffee 2_coffee maker ^^= platform 116 is also correspondingly disposed on each sub-tenk region. However, the way of placing the platform 116 is reduced. The aperture ratio, and the position of the spacers 123, which are often designed as in the ΐβ diagram, also causes a problem of wasting aperture ratio.

In view of the above problems of lowering the contrast ratio and the aperture ratio, in the current liquid crystal display process, the attempt of adjusting the alignment protrusion 122, the spacer 123 or the contact hole lb is attempted. For example, please refer to the temple map. It is disclosed in U.S. Patent Publication No. 20-89928 that the color filter substrate 12 is provided with a spacer 123' and the array substrate is also provided with a contact hole 115' and the spacer 123 is disposed directly above the contact hole 115. And the two sides of the platform of the opening of the contact hole 115. In addition, a light shielding layer 124 (BM) is disposed on the spacer 123 to simultaneously shield the light leakage of the spacer 123 and the contact hole 115 for the purpose of increasing the aperture ratio and improving the contrast. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a liquid crystal display panel and a method of fabricating the same. Another object of the present invention is to increase the aperture ratio of a liquid crystal display. Still another object of the present invention is to improve the image contrast of a liquid crystal display. The present invention provides a reflective or transflective liquid crystal display panel having a high aperture ratio and a high contrast ratio. Taking a reflective liquid crystal display panel as an example, each sub-dielectric region of the first substrate of the liquid crystal display panel includes at least a common line, a gate line, a switching element structure, a data line, a contact hole, and a storage. 201102726

Further, a light shielding layer is disposed above the contact hole, the filling member, the alignment protrusion or the spacer, and the contact hole and the filling member may be located at the same position. Capacitor structure, a flat layer, components, and the right one is determined - according to the (4) of the present - the real-life reflex-type transparent LCD display panel, the silk-substrate forming the filling step in the first step through - Light f patterning the filling layer, the filling layer being exemplified by an organic material. Then, in the subsequent production of the _ scale light filling layer, and remove the remaining part to form the first block in the simple hole _, the concave _ contact hole can be filled through the first block, the scale is formed second The block is on the first block so that the relative position of the contact hole is $@@amp; The last two "description" - the substrate is set up and formed - the liquid crystal layer is between the first substrate and the substrate. It is important to note that the thickness of the object is approximately equal to that of the liquid layer. It can also be used as a aligning object. The first substrate of the 曰8 is more versatile.

δ is placed at the same position again, that is, the spacer is used to change the distribution of the power line, so that the surrounding liquid crystal is attached to the gap of the 201102726 object side to achieve the effect of wide viewing angle technology == the barrier or the directional protrusion Below, and because of the system = hang, 曰 and ^ light layer above the spacer or alignment λ, used to shield the dark state of the light leakage problem, which can simultaneously shield the contact, the gap "" Leakage light, and the contact hole system is exemplified by an organic material to fill the platform of the 'phase-car-handling technology or only using the platform on both sides of the contact hole to fix the method _ the present invention can only be added to the liquid crystal display panel

The aperture ratio 'increased image to tb degree' is more likely to cause alignment errors in the substrate assembly. X [Embodiment] In the first FIG. 1C, since the spacer (2) must be just on both sides of the opening of the contact hole 115, the panel pitch can be stably maintained. Thus, slight errors in the process, such as the width of the spacer, the width of the contact opening, and the alignment error of the array substrate and the color filter when assembled, are very likely to cause errors in the panel cell gap resulting in yield loss. Case. In view of the above, in order to improve the poor contrast caused by the conventional liquid crystal display technology and the problem of reduced aperture ratio, the present invention proposes a new design, by which the aperture ratio of the liquid crystal display can be increased, and the aperture ratio can be further improved.

Wherein, the filler member includes the first block singer, the contact hole 222 and the second block of the second block 411b, and the thickness of the second block 411b is approximately equal to the thickness of the liquid crystal layer 5, The width of the two blocks 411b is substantially the same and is cylindrical. According to the method of the second embodiment of the present invention, the position of the filling member 4ΐ is not limited to the lower portion of the blue light-emitting unit, and may be simultaneously disposed on the red calender unit 311R and the green calender unit 3nG. As shown in Figure 3E. Referring to Figs. 5A to 5D, which are diagrams showing the difficulty of the semi-transparent and transflective liquid crystal display panel according to the method of the present embodiment, respectively. The structural features shown in the upper view of this embodiment are the same as those in the fourth embodiment, so that the top view of the embodiment is not additionally provided. However, it is worth noting that the cross-sectional view shows that the difference between this figure and the aforementioned No. 3-8 to 4: the figure is the presence or absence of the entire layer at 5 weeks, that is, the liquid crystal display panel shown in this figure has only a single pitch. Therefore, the above structural difference is roughly described as follows in the cross-sectional view of a_a, line and B-B' line in Fig. 48. Please refer to FIG. 5A, which is a cross-sectional view along line AA of FIG. 4A. 17 201102726 The 帛 substrate 20 (5) in FIG. 8 has a plurality of sub-pixel regions (10). The primary pixel region 100 also has a reflection region R and penetration. The region τ and the counter 223 are located in the reflective region R.
