Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel, and more particularly to a liquid crystal display panel capable of avoiding contamination of liquid crystals. ‘5 [Prior Art] Referring to the cross-sectional view of the conventional liquid crystal display panel shown in Fig. 1, the liquid crystal display panel 1 is composed of an upper substrate n, a lower substrate 12, and a liquid crystal 13. The upper substrate Π and the lower substrate 12 are separately fabricated. After the upper substrate and the lower substrate 12 are fabricated, the assembly process is performed to connect the upper substrate 11 and the lower substrate 12. It is a conventional practice to fill the liquid crystal 13 on the lower substrate 12, apply the sealant 14 to the edge of the upper substrate 11, and align the upper substrate u with the lower substrate 12. After the enamel is irradiated with ultraviolet light to harden the sealant 14, the upper substrate n and the lower substrate 12 are fixed. 15 However, before the sealant 14 is hardened, the sealant 14 may contact the contaminated liquid crystal 13' to affect the display quality of the liquid crystal display panel 1. Therefore, the conventional solution to this problem is to reduce the range of filling of the liquid crystal 13, but it also causes uneven cell pitch (cell Gap) between the upper substrate 11 and the lower substrate 12, and bubbles are formed at the edge of the liquid crystal display panel 1. After that. Referring to FIG. 2, a schematic cross-sectional view of a conventional liquid crystal display panel is shown. As shown in the figure, the liquid crystal display panel 2 is composed of an upper substrate 21, a lower substrate 22, and a liquid crystal 23 disposed between the upper substrate 21 and the lower substrate 22. Composition. Further, a retaining wall 25 is provided to block the sealant 24, however, this causes the 1362543 occupied area of the edge of the liquid crystal display panel 2 to increase, and the availability of the upper substrate 11 or the lower substrate 12 is reduced by 0. [Invention] The invention provides a liquid crystal display panel comprising: an upper substrate and a lower substrate. The upper substrate is provided with a support, wherein the support is located in a peripheral region of the upper substrate and has a recess, and the lower substrate is disposed opposite to the upper substrate.

The lower substrate 32 is disposed opposite to the upper substrate 31, and is provided with at least one element 32 of the pixel 32 to receive the surface display material ’ to display a picture. The upper substrate 31 is provided with a shirt color filter composed of a black matrix 311 and a color layer 312. The color layer 312 is disposed corresponding to the pixel 321 , and the colors of the color layers 312 corresponding to different pixels 321 can be different to provide Color display. _ The black matrix 311 disposed at the edge of the upper substrate 31 is used to shield the light to increase the display contrast. In the present embodiment, the black matrix 3 11 is a black film having an edge in a square shape and an internal grid-like structure, and for the convenience of the drawing, the internal grid is only shown as an array of 3×5.

The retaining walls 351, 352 on both sides of the support 35 block the frame glue 34 so that the sealant 34 does not directly contact the liquid crystal 33. Therefore, in the process of assembling the upper substrate 31 and the lower substrate 32, the problem that the sealant 34 contaminates the liquid crystal 33 is not caused, so that the range in which the liquid crystal 33 is filled can be increased.

As shown in the figure, the material of the support 35 of the present embodiment is an acrylic resin film for making a photo spacer 36, which uses a halftone mask (Half Tone) in the same process. Together, ',' is referred to as a PS resin layer in the present specification. The optical spacer 36 is supported between the upper substrate 31 and the lower substrate 32 so as to maintain a uniform pitch after the upper substrate 31 and the lower substrate 32 are assembled. Then, the support 35 of the present embodiment is formed by a mask exposure development method. First, for the exposure process, a layer of ps is applied (not shown), and then a half-tone mask (not shown) is placed between a light source (not shown) and the upper substrate 3 i and illuminated. a light (not shown) is defined on the ps layer to define the outer edge of the support 35, a predetermined width w of the groove 354, a predetermined depth h, and the size of the optical spacer 36. Developing process: The upper substrate = immersed in a developer (not shown) to visualize the defined pattern on the PS layer. Thereafter, the sealant 34 is applied to the recess 354, and the liquid crystal 33 is filled between the upper substrate 31 and the lower substrate 32, and the upper substrate 31 and the lower substrate 32 are aligned. Finally, the liquid crystal display panel 3 is completed by irradiating a light such as ultraviolet light (ultra Violet Llght hereinafter referred to as uv light) for a period of time to harden the sealant 34. In the present embodiment, the UV light is incident from the upper substrate 31 toward the lower substrate 32. 5 Please also refer to the manner in which the support of another embodiment of the present invention shown in Fig. 6 is made. In order to save space, we only detail the differences between this production method and the above-mentioned production methods. In this embodiment, the support 35 is also formed by the reticle exposure development method disclosed in the previous embodiment, and only the support 35 of the embodiment is disposed on the black matrix 311 without occupying the upper substrate 31. The area of the edge 10 is used to make the support 35, so the utilization of the upper substrate 31 is increased. However, since the black matrix 311 is a material that is opaque, after the upper substrate 31 and the lower substrate 32 are aligned and the illuminating port is irradiated for a period of time to harden the sealant 34, the UV light is passed from the lower substrate 32. In the direction of the upper substrate 31, the liquid crystal display panel of the present invention has at least the following advantages: 1. The two sides of the support block can block the frame glue and the liquid crystal to avoid the frame glue. • Direct contact with the LCD. Therefore, when the liquid crystal is injected, it is not necessary to reduce the range of the liquid crystal filling, so the uniformity of the cell pitch between the two substrates is increased. Second, compared with the conventional use of the wall barrier frame glue, the hair and the Ming only use the support 2 〇 support to avoid contamination of the liquid crystal. In this way, the area of the edge of the substrate can be saved to increase the availability of the substrate. It should be noted that in the above embodiment, the upper substrate is a color calender a substrate, and the lower substrate is an active array substrate. However, the upper substrate is not limited to being a color filter substrate, and the lower substrate is not limited to the active array substrate. In 1362543, in other embodiments, the upper substrate may also be an active array substrate, and the lower substrate is a color filter substrate. Further, one of the upper substrate or the lower substrate may be a touch panel or have a COA (color filter 〇). n array ) structure.
