To make the above and other objects, features and advantages of the present invention more apparent, the following DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a top view of a liquid crystal light-shielding panel according to an embodiment of the present invention, and FIG. 2A and FIG. 2B respectively. 1 is a perspective view of the area A10 of the liquid crystal light-shielding panel of FIG. 1 before and after voltage application. Referring to FIG. 1, the liquid crystal light-shielding panel 200 of the present embodiment has a plurality of first strip regions 202 and a plurality of second strips arranged in a staggered configuration. The region 204. That is, each of the first strip regions 202 has a second strip region 204 on both sides, and each of the strip strip regions 204 has a first strip region 202 on both sides. Please refer to FIG. 2A. 2B, the liquid crystal light-shielding panel 200 includes a first substrate 210, a second substrate 220, a liquid crystal layer 230, and a plurality of strip insulations 11 200844544 P060208LOZ1TW 23509twf.doc/n 240 (only one is shown in FIG. 2A) a first polarizing plate 250 and a a second polarizing plate 260. A first electrode layer 212 and a first alignment layer 214 covering the first electrode layer 212 are disposed on the inner surface of the first substrate 210. A second electrode layer is disposed on the inner surface of the second substrate 220. 222 and a second alignment layer 224 covering the second electrode layer 222. The liquid crystal layer 230 is disposed between the first alignment layer 214 of the first substrate 210 and the second alignment layer 224 of the second substrate 220. In this embodiment, The liquid crystal molecules 232 f of the liquid crystal layer 230, using negative liquid crystal molecules 'but are not intended to limit the invention. The parallel dielectric constant of the negative liquid crystal molecule 232 is smaller than the vertical dielectric constant, so that the long axis of the negative liquid crystal molecule 232 will be perpendicular to the electric field direction when subjected to an electric field. The first alignment layer 214 and the second alignment layer 224 both vertically align the liquid crystal molecules 232 of the liquid crystal layer 230, but the first alignment layer 214 pre-tilts the liquid crystal molecules 232 in a first direction D10, and the second alignment layer 224 makes the liquid crystal The molecules 232 are pretilted in a second direction D20. The first direction D10 is substantially perpendicular to the second direction D20. In this embodiment, the strip insulators 240 are disposed on the first alignment layer 214 and the second alignment layer 224 and are located in the first strip region 202. Specifically, each of the strip-shaped insulating members 240 is distributed in a first strip-like region 202 in an elongated appearance. In addition, although the strip insulator 240 of the present embodiment is disposed on the first alignment layer 214 and the second alignment layer 224 at the same time, in other embodiments, the strip insulator 240 may be disposed only on the first alignment layer 214 or the first On the second alignment layer 224. The first polarizing plate 250 is disposed on the outer surface of the first substrate 210, and the second polarizing plate 260 is disposed on the outer surface of the second substrate 220, and both allow light having a linear polarization direction parallel to the first direction D10 to pass. . 12 200844544 P060208LOZ1TW 23509twf.doc/n FIGS. 3A and 3B are partial cross-sectional views of the liquid crystal light-shielding panel of FIG. 1 before and after voltage application, respectively. Referring to FIG. 2A and FIG. 3A, the light source passes through the second polarizing plate 260 and becomes linearly polarized light, and its linear polarization direction is parallel to the first direction D10. Since the liquid crystal molecules 232 are vertically aligned by the first alignment layer 214 and the second alignment layer 224, when no electric field exists between the first electrode layer 212 and the second electrode layer 222 before the voltage is applied, the liquid crystal molecules 232 are mainly subjected to The first alignment layer 214 and the second alignment layer 224 are arranged vertically. At this time, the linearly polarized light does not change its linear polarization direction after passing through the liquid crystal layer 230, so the linearly polarized light can still be emitted outward through the first polarizing plate 250. In other words, both the first strip region 202 and the second strip region 204 of the liquid crystal light-shielding panel 20 are in a state of allowing light to pass therethrough. Referring to FIG. 2B and FIG. 3B, when a voltage difference is generated between the first electrode layer 212 and the second electrode layer 222 to generate an electric field, the long axis of the negative liquid crystal molecules 232 will rotate in a direction perpendicular to the direction of the electric field. In addition, since the pretilt directions of the liquid crystal molecules 232 adjacent to the first alignment layer 214 and the second alignment layer 224 are perpendicular to each other, the liquid crystal molecules 232 after being driven will be in a twisted nematic (TN) manner. Actuate and cause the polarization of the linearly polarized light to produce a 90 degree rotation. However, the strip insulating member 240 is present in the first strip region 2〇2, and the strip insulating member 240 is absent in the second strip region 204, so that the liquid crystal molecules 232 in the first strip region 2〇2 are driven. The required electric field strength will be greater than the electric field strength required to drive the liquid crystal molecules 232 in the second strip region 204. In other words, if the electric field between the first electrode layer 212 and the second electrode layer 222 is controlled to be at an appropriate intensity, only the liquid crystal molecules 232 in the second strip 204 can be driven to act in a twisted nematic manner, and let the first 13 200844544 P060208LOZ1TW 23509twf.doc/n Most of the liquid crystal molecules 232 in the strip region 202 are maintained in a vertically aligned state. In other words, after the linearly polarized light passing through the second polarizing plate 260 passes through the liquid crystal layer 230 of the second strip region 204, its linear polarization direction is rotated by 9 degrees and cannot pass through the first polarizing plate 25A. However, the linearly polarized light passing through the second polarizing plate can pass through the first polarizing plate 25G after the liquid crystal layer 23G which has passed through the first strip-like region and whose linear polarization direction remains unchanged. That is, at this time, the liquid crystal light-shielding panel 200 can function as a parallax barrier member as described in the prior art. It can be seen that the liquid crystal light shielding panel 200 of the embodiment can be electrically switched between the full light transmission and the partial light transmission. In the towel of this embodiment, the strip-shaped insulating member may be formed by polymerizing a plurality of reactive group monomers. Specifically, the molecular structure of the reactive monomer can be:

Referring to 2/, 2B, when manufacturing the liquid crystal light-shielding panel, the liquid crystal layer is first sealed between the first substrate 21A and the second substrate 22A. Among them, the liquid crystal layer is internally dispersed with a plurality of reactive group monomers (not shown). Next, the ultraviolet light Uv is irradiated to a partial region of the liquid crystal layer 230 through the mask 50. This day, the reactive monomer is polymerized to form a strip-shaped insulating member 240 in a region irradiated with ultraviolet light uv. The strip-shaped insulating members 24G shown in FIGS. 2A, 2B, 3A, and 3B are for illustrative purposes only and are not intended to express the actual shape of the strip-shaped insulating member 240. Further, depending on the different reaction substrates The material properties of the body, the method of polymerizing the reactive monomer may also be irradiating other types of light, heating or other suitable means. In addition, the liquid crystal layer 23 may be doped with a palmitic dopant (chirald〇). Pant), which has the function of helping the liquid crystal molecules 232 to be regularly arranged. Referring to FIG. 2A, the material of the first alignment layer 214 and the second alignment layer 224 is, for example, polyimide or other suitable material, and the first alignment The layer 214 and the second alignment layer 224 may adopt a contact alignment or a non-contact I' type alignment. The non-contact alignment is, for example, rubbing, and the non-contact alignment is, for example, a photo-alignment technique, an ion beam alignment technique, and a plasma. The beam alignment technique, the oblique vapor deposition alignment technique, or the laser interference technique is used to form the micro trench. After the alignment, the first alignment layer 214 and the second alignment layer 224 can vertically align the liquid crystal molecules 232 and pretilt them. among them, The pretilt angle of the crystal molecules 232 is, for example, greater than 15 degrees and less than or equal to 15. Further, the material of the first electrode layer 212 and the second electrode layer 222 may be indium tin oxide, indium zinc oxide or other transparent conductive material. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The liquid crystal light-shielding panel 2 is similar in that the position of the strip-shaped insulating member 340 is different from the position of the strip-shaped insulating member 240. Only the differences between the two embodiments will be described below, and the description of the similar parts will be omitted. In this embodiment, the strip-shaped insulating member 34 is disposed between the first electrode layer 322 and the second alignment layer 324. However, in other embodiments, the strip-shaped strip member 3 40 may be disposed on the first electrode. Between layer 312 and first alignment layer 314 is disposed between first electrode layer 312 and first alignment layer 314 and between second electrode layer 322 and second alignment layer 324. Strip insulator 340 is located First strip zone 30 2. Referring to FIG. 5A, the light source will become linearly polarized light after passing through the first polarizing plate 350 and its linear polarization direction is parallel to the first direction D10. Before the driving voltage is applied, the liquid crystal molecules 332 are subjected to the first alignment layer 314 and The vertical alignment of the second alignment layer 324, so that when no electric field exists between the first electrode layer 312 and the second electrode layer 322, the liquid crystal molecules 332 are mainly vertically affected by the first alignment layer 314 and the second alignment layer 324. At this time, the linearly polarized light does not change its linear polarization direction after passing through the liquid crystal layer 330. Therefore, the linearly polarized light can still be emitted outward through the second polarizing plate 360. In other words, both the first stripe region 302 and the second stripe region 304 of the liquid crystal light-shielding panel 300 are in a state of allowing light to pass therethrough. Referring to FIG. 5B, when a voltage difference is generated between the first electrode layer 312 and the second electrode layer 322 to generate an electric field, the long axis of the negative liquid crystal molecules 332 will rotate in a direction perpendicular to the direction of the electric field. In addition, due to proximity to the 16th 200844544 P060208LOZ1TW 23509twf.doc/n

The alignment direction 314 and the pretilt direction of the liquid crystal molecules 332 near the second alignment layer 324 are perpendicular to each other'. Therefore, the liquid crystal molecules 332 after being driven will be operated in a twisted nematic manner, and the polarization direction of the linearly polarized light is generated 9 turns. Degree of rotation. However, the strip insulating member 34 is present in the first strip region 302, and the strip insulating member 340 is absent in the second strip region 304, so that the electric field required to drive the liquid crystal molecules 332 in the first strip region 302 is driven. The intensity will be greater than the electric field strength required to drive the liquid crystal molecules 332 in the second strip region 304. In other words, when the electric field between the right control gate electrode layer and the second electrode layer 322 is at an appropriate intensity, only the liquid crystal molecules 332 in the second strip region 3〇4 can be driven to act in a twisted nematic manner, and Most of the liquid crystal molecules 332 in the strip region 3〇2 are maintained in a vertically aligned state. In other words, the linearly polarized light passing through the first to tenth 'polarizing plate 350 after passing through the liquid crystal layer 33 of the second strip region 304' will be rotated by the twisted direction and cannot pass through the second polarizing sheet. However, the linearly polarized light passing through the first polarizing plate 35 在 passes through the liquid crystal layer 33 of the first strip region 302, and its linear polarization direction remains unchanged to pass through the second polarizing plate. That is, the slab 300 can exhibit the parallax resistance as described in the prior art. It can be seen that the liquid crystal glazing panel 300 of the present embodiment is electrically switched between the 70-light transmission and the partial light transmission. The refractive index n of the phase f is, for example, but not limited to, the ordinary refractive index of the liquid crystal molecules 332 of the η ΓΓΓ layer, and the surface is, for example, but not limited to the liquid crystal molecules above the top surface of the flat H-edge 34G. 332 17 200844544 P060208LOZ1TW 23509twf.doc/n can be arranged more regularly.

Figure 6A and Figure 6B are diagrams showing a method of manufacturing the edge of the liquid crystal light-shielding panel of Figure 5A. Referring to FIG. 6A and FIG. 6A, in the embodiment for fabricating the mirror member 340, the first electrode layer 3ΐ4 and the —substrate 310 are provided first, but at this time, the alignment layer is not formed on the first substrate 31. A two-material layer 342 is formed on the first electrode layer 314 of the first substrate 310. The insulating material layer 342 is, for example, a photosensitive material. In more detail, the photosensitive photoresist material is preferably transparent. After the light material has refraction similar to the refractive index of the liquid crystal molecules, the insulating material layer 342 is exposed to light using a mask 50. Then, a developing process of the exposed insulating material layer 342 is performed to form a strip-shaped insulating member 340 as shown in Fig. 6B on the first electrode layer 314 of the first substrate 310. The exposure and development processes described above are well known to those of ordinary skill in the art and will not be described in detail herein. Of course, the method of manufacturing the strip insulator 340 is not limited to the embodiment described with reference to Figures 6A and 6B, and many of those skilled in the art are well known for making strip insulators 34 FIG. 7A and FIG. 7B are partial cross-sectional views of the liquid crystal light-shielding panel according to still another embodiment of the present invention before and after voltage application. Referring to FIG. 7A, the liquid crystal light-shielding panel 400 of the present embodiment is similar to the liquid crystal light-shielding panel 2A of FIG. 2A, and the difference is mainly that the liquid crystal light-shielding panel 400 of the present embodiment has no strip-shaped insulating member' but the first electrode 412 and the first The two electrodes 422 are strip-shaped and located in the first strip region 402. 18 200844544 P060208LOZ1TW 23509twf.doc/n Referring to FIG. 7A, the light source will become linearly polarized light after passing through the first polarizing plate 45 and its linear polarization direction is parallel to the first direction D1. Since the liquid crystal molecules 432 are vertically aligned by the first alignment layer 414 and the second alignment layer 424, the liquid crystal molecules 432 are mainly subjected to the first when no electric field exists between the first strip electrodes 412 and the second strip electrodes 422. The alignment layer 414 and the second alignment layer 424 are arranged vertically. At this time, the linearly polarized light is not changed in the direction of linear polarization after passing through the liquid crystal layer 430, so the linearly polarized light can be emitted outward through the second polarizing plate 460. In other words, the first strip region 402 and the second strip region 4〇4 of the liquid crystal light-shielding panel 400 are in a state of allowing light to pass therethrough. As is clear, in Fig. 7B, when an electric field is generated with a voltage difference between the first strip electrode 412 and the second strip electrode 422, the long axis of the negative liquid crystal molecules 432 will rotate in a direction perpendicular to the direction of the electric field. In addition, since the pretilt directions of the liquid crystal molecules 432 close to the first alignment layer 414 and the second alignment layer 424 are perpendicular to each other, the driven liquid crystal molecules 432 will be operated in a twisted nematic manner and linearly polarized. The polarization direction produces a rotation of 9 〇t degrees. However, only the liquid crystal molecules 432 in the first strip 402 are forked to the electric field between the first strip electrode 412 and the second strip electrode 422 to act in a twisted nematic manner, but the second strip region The liquid crystal molecules 432 in 4〇4 do not have any electrodes up and down and are not driven and remain mostly in a vertically aligned state. In other words, after the linearly polarized light passing through the first polarizing plate 45 turns through the liquid crystal layer 430 of the first strip region 402, its linear polarization direction is rotated by 9 degrees to pass the first polarizing plate 460. However, after the linearly polarized light passing through the first polarizing plate 450 19 200844544 P060208LOZ1TW 23509twf.doc/n passes through the liquid crystal layer 43 of the second strip region 4〇4, the linear polarization direction remains unchanged and can pass through the second The polarizing plate 46 is 〇. That is, the liquid crystal light-shielding panel 4GG can function as a parallax resistance PIitg piece as described in the art. It can be seen that the liquid crystal light shielding panel of the embodiment can be electrically switched between the full light transmission and the partial light transmission. In addition, the material of the first strip electrode 412 and the second strip electrode 422 may be indium tin oxide, indium zinc oxide or other transparent conductive material. 。 Figure 8 is a schematic view of a display device in accordance with an embodiment of the present invention. Referring to FIG. 8, the display device 5 of the embodiment includes a display module 51 and a liquid crystal shutter 520. The liquid crystal light-shielding panel 52A may be any one of the liquid crystal light-shielding panels of the foregoing two embodiments or variations thereof, and will not be described herein. The liquid crystal light shielding panel 520 is disposed on the display module 51A. The display module 510 has a plurality of first regions 512 and a plurality of second regions 514 arranged in a staggered manner. When the display module 510 is in the 3D display mode, the first area 512 is adapted to display an image for viewing by the user's right eye, and the second area Η# is adapted to display an image for viewing by the user's left eye. When the display module 51〇I is in the 2D display mode, both the first area 512 and the second area 514 display only 2D images. The liquid crystal shutter panel 520 is located between the user display modules 510. When the liquid crystal light-shielding panel 520 is electrically driven to be partially transparent, the image displayed by the first region 512 passes through the light-transmitting region of the liquid crystal light-shielding panel 52 to reach the right eye of the user, and the image displayed by the second region 514 is The left eye of the user is reached through the light transmitting area of the liquid crystal light shielding panel 520. Thereby, the right eye and the left eye of the user respectively view the right eye image and the left eye 20 200844544 P060208LOZ1TW 23509twf.doc/n image, thereby allowing the user to have a feeling of viewing the 3D image. When the liquid crystal light-shielding panel 520 is not electrically driven to transmit light, the 2D images displayed by the first area 512 and the second area 514 can be received by the user through the liquid crystal light-shielding panel 520.
