The result is the bottom layer of the edge area ιΐ6 (color crossing = pattern layer 17 (UX and black matrix layer _ ratio display) The bottom layer C in the region 112 is instead a case of edge gap mura. In summary, the lateral stiffness of the glass substrate of the liquid crystal display panel varies with the thickness of the glass substrate. The trend of small size and large size is decreasing in higher order. In other words, in a small-sized or large-sized liquid crystal display panel, if the lateral stiffness of the glass substrate is insufficient, the panel gap of the liquid crystal display panel is There is not enough support force, the uniformity of vOZITW 25570twf.doc/n 201044080 ==:::=== [Summary of the Invention] The present invention provides a liquid crystal display panel, which can improve the liquid crystal display panel.

[Embodiment] The liquid crystal display panel of the present invention is provided with a second spacer in the edge region in addition to the first spacer for maintaining the liquid crystal gap in the display region, thereby preventing the liquid crystal gap at the edge region from being lowered. In particular, by increasing the area occupation ratio of the first spacer from the display area of the liquid crystal display panel to the direction of the sealant region, stress concentration caused by the second spacer can be prevented, and liquid crystal can be avoided. The protective layer of the display panel is cracked at the edge region position. The liquid crystal display panel of the present invention can maintain a good liquid crystal gap in both the edge region and the display region, and can solve the problem of uneven stress distribution at the edge region. Several preferred embodiments of the liquid crystal display panel of the present invention will be further described below with reference to the drawings. 2 is a cross-sectional view showing a liquid crystal display panel in accordance with a preferred embodiment of the present invention. The liquid crystal display panel 200 includes a first substrate 210, a plurality of first spacers 220, a plurality of second spacers 230, a second substrate 240, and a liquid crystal layer 250. The liquid crystal display panel 200 has a display area 212, a sealant area 214 surrounding the display area 212, and an edge area 216 between the display area 212 and the sealant area 214. The first spacer 220 is disposed on the first substrate 210 and located in the display area 212. The second spacer 230 is disposed on the first substrate 210 and located in the edge region 216. The area of the second spacer 230 for the edge region 216 is from the display region 212 to the sealant 10 201044080 cZITW 25570twf.doc/n Area 214 is increasing. The second substrate 240 is opposite to the first substrate 210. The liquid crystal layer 250 is disposed between the first substrate 210 and the second substrate 240. With reference to FIG. 2, in one embodiment of the present invention, the liquid crystal display panel 200 further includes a sealant 260 disposed in the sealant region 214 and combined with the substrate 210 and the second substrate 240. The sealant 260 described above includes one of a photocurable adhesive and a heat curable adhesive. o In addition, the first substrate 210 may be a color filter substrate, so that the liquid crystal display panel 200 is fully colored. As shown in FIGS. 2 and 3, the first substrate 210 may have a color filter pattern layer 27 and a black matrix layer 2''. Generally, as long as the pattern of the first __ 22G and the second spacer 23 设计 are first designed on the same reticle, the first spacer 220 and the second can be simultaneously fabricated in the same reticle process. The spacer 23G has almost the same degree. In particular, the first gate, the wood=70 and the black matrix layer 28G, the second spacer, the array 280. Because of the different bottoms: = in the ❹ 间隙 物 220 and the first 睹犏 睹犏 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍 侍The height of the interstitial material contacting the second substrate 24A has a = element array substrate on which the halogen is displayed/not displayed. In order to switch the respective elements, it is true that the second spacer 230 is said to be the second spacer 23 at the boundary of the disc-gate gap h and the first spacer 2_object 220. The 4=two product occupancy rate, that is, the area 214 is gradually increased by the same area occupancy rate as the first rate from the head area 212 to the frame glue. 201044080 irw 25570twf.doc/n A linear change in the area occupancy of the second spacer 230 can be performed by the following two embodiments, that is, the density of the second spacer 230 is fixed, and each second spacer is changed. The area of 230; or the area of each of the second spacers 230 is fixed, changing the set density of the second spacers 230. Referring to FIG. 2, in the liquid crystal display panel 200, when the distribution density of the second spacers 230 is constant, the area of the second spacers 230 gradually increases from the display area 212 to the sealant area 214. In more detail, the second spacer 230 may have the same distribution density as the first spacer 22'. The difference is that the area of the second spacer 230 varies linearly. Taking a cylindrical spacer as an example, at the boundary between the display area 212 and the edge area 216, the diameters of the second spacer 230 and the first spacer 220 are initially ri, and then the diameter of the second spacer 230 is directed to the frame. The glue zone 214 is gradually linearly increased to r2, r3, etc., that is, the diameter (rl, r2, r3, etc.) is calculated to make the area occupation ratio of the second spacer 230 from the display area 212 to the plastic frame area. 214 increases linearly. Alternatively, it may be designed such that the area of each of the second spacers 230 and each of the first spacers 220 is the same, but the distribution density gradually increases from the display area 212 toward the sealant area 214. Fig. 3 is a schematic top plan view showing another liquid crystal display panel of a preferred embodiment of the present invention. The liquid crystal display panel 202 is similar to the above-described liquid crystal display panel 2, and the same components are designated by the same reference numerals and will not be described again. It should be noted that, in the liquid crystal display panel 202, when the area of the first spacer 220 and the second spacer 23 is constant, the distribution density of the second spacer 23 0 is changed from the display area 2 j 2 to The sealant area 214 is gradually increasing. 12 2〇1044080咖25570twf.doc/n 2〇1044080咖25570twf.doc/n Ο In more detail, the area of the second spacer 230 is the same as the area of the first spacer 220, and the difference is the second spacer 23 The density of helium varies linearly. Taking a cylindrical spacer as an example, at the parent boundary of the display area 212 and the edge area 216, the distribution density of the second spacer 230 and the first spacer 220 are initially the same. Thereafter, the distribution density of the second spacers 230 gradually increases linearly toward the sealant region 214, that is, the distribution density is calculated to make the area occupancy ratio of the second spacers 230 from the display region 212 to the plastic frame region. 214 increases linearly. Since the second spacer 23 in the edge region 216 initially has the same area occupancy as the first spacer 220 in the display region 212, there is no sudden change in the elastic coefficient (κ) value. Causes the glass to bend and deform. In other words, if the area of each of the second spacers 23〇 is the same as that of each of the first spacers 220, the first region of the edge region 216 closest to the display region 212 has the same density as the display region 212. It then gradually increases toward the sealant region 214. The present invention does not limit the distribution of the second spacer 23 〇= (as shown in FIG. 3 ), as long as the area occupancy of the second spacer 23G increases from the display area 212 to the seal area 214 _ The distribution of other forms. As described above, the liquid crystal display panel 200, 202 can prevent the liquid crystal gap from being lowered in the edge region 216 = the first spacer - 23G'. Further, since the stress is distributed by the arrangement in which the accumulation ratio of the second spacer 23G increases from the display region 212 to the sealant region 214, stress concentration in the second spacer can be prevented. Therefore, the liquid crystal display panel·(10) can maintain a good liquid crystal gap in both the k-edge region 216 and the display region 212, and 13 201044080 ----------liW 25570twf.doc/n can solve the inner edge of the edge region 216雍七八#· Layer, circuit component crushing and other issues. * Uniform resulting protection of the door gap: = ir The variation of the second = rate of the liquid crystal display panel of the preferred embodiment. Referring to Figure 4, assuming that the d It occurs within the elastic deformation range, the second gap The condition of the object 130 should be in accordance with Hooke's Law x, where k is the number of the interstitial compression. Since the sealant 260 generally has glass fiber, the frame seal 26 can be regarded as an incompressible body, so the compression of the sealant (four) The amount is regarded as 〇. However, in the display area 212, a fixed atmospheric pressure (the atmospheric pressure) is also applied, so the first spacer 22 in the entire display area 212 has a fixed amount of compression X1. The first substrate 210 and the second substrate 240 of the display region 212 and the edge region 216 do not have a bending phenomenon, and the stress state of each region of the liquid crystal display panel 2〇〇, 202 can be estimated according to Hooke's law, without counting the second. The area occupancy of the spacer 230 varies. The optimal condition is that the area occupancy of the second spacer 230 in the edge region 216 varies linearly from the display region 212 to the frame region 214. As can be seen from the graph of Fig. 4. Second room The area occupancy rate of the object 230 is inversely proportional to d (distance), that is, the area occupancy rate is larger at the sealant region 214, and the smaller the area occupying the second spacer 230 is, the farther away from the sealant region 214 is. Yes, the area of the spacers 220, 230 in the intersection area of the edge area 216 and the display area 212 is the same, or the gap between the display area 212 and the edge area 216 is linearly changed to avoid sudden change of the area occupancy. The first substrate 210 and the second substrate 240 are bent. 14 201044080 JZ1TW 25570 TW / n Figure 5 is a schematic view of a liquid crystal display device according to a preferred embodiment of the present invention.
