Description

567381 V. Description of the Invention (1) [Field of the Invention] The present invention relates to a liquid crystal display panel [Known Technology], i. Generally speaking, a liquid crystal display panel is formed by sandwiching a partition in the middle of a glass substrate, and two or f liquids fill the space surrounded by the sealing frame. The partition placed between the two transparent substrates maintains a fixed distance between them, forming a fixed two to show the consistency of the quality of the two meniscus plates. In order to ensure that the partitions of the display system include spherical ones, such as the special partitions scattered on the substrate, and the columnar partitions made of grease, they are arranged on the substrate. "It is by coating photosensitive resin on the substrate, and then exposing the above-mentioned columnar partitions to the same, and it has the advantage that the distance between the two transparent substrates can be controlled by controlling the sensitivity." The amount of resin controls the thickness of the liquid crystal layer. The maintenance of a fixed distance between the front-lighting partitions is performed by passing the two-stomach partition of the stomach at the normal temperature π position between the two transparent substrates, thereby maintaining the uniform thickness of the liquid crystal layer at the A position. The layers are at various temperatures. However, at higher temperatures (such as 40 ° C or above), ‘, 4 questions’, that is, the liquid crystal filled between the two transparent substrates is thermally expanded.

Page 5 567381 V. Description of the invention (2) Wave-shaped deformation occurs between the transparent substrates. This deformation causes the thickness and partial unevenness of the liquid crystal layer to cause irregularities in the contrast between the light and dark of the development, thereby reducing the development quality. In particular, in a liquid crystal display panel having a large screen or a large-area substrate, the transparent substrate is considerably deformed due to the pressure generated by the thermal expansion of the liquid crystal, which results in a significant decrease in the development quality. : In order to solve this problem, Japanese Patent Publication JP-A-8 (1 996) -1 5708 proposes a liquid crystal display panel, which includes a pair of transparent substrates connected together by a sealing frame, and liquid crystal is filled between the transparent substrates. The gap, a plurality of hardware partitions and a plurality of elastic partitions are each between two transparent substrates, and the diameter of the elastic partition is larger than the diameter of the hardware partition in a normal state. The following is the principle of avoiding the aforementioned development irregularities. In the liquid crystal display panel, the elastic deformation of the elastic partition is caused by the pressure generated when the two transparent substrates are connected, so that the size of the elastic partition at normal temperature is substantially the same as that of the hard partition, so that the A fixed space is maintained between the transparent substrates. Therefore, the thickness of the liquid crystal layer injected between the transparent substrates can be maintained at a certain thickness at a certain position. When the temperature around the liquid crystal display panel rises from normal temperature to a relatively low temperature, for example, about 40 degrees Celsius, the liquid crystal filled between the two transparent substrates undergoes thermal expansion, which causes the transparent substrate to expand due to the liquid crystal. Pressure to expand outwards:-shape. According to the deformation of the substrate, each compressed elastic partition is

Description of the invention (3) Each increase of elasticity to increase its direct effect _ ^ = the position corresponding to the three transparent substrates, which is supported by the aforementioned wave-shaped & In order to avoid maintaining the constant f on the transparent substrate. In contrast, the distance between the entire transparent substrates substantially improves the thickness of the liquid crystal layer corresponding to the developed image, and the thickness of the liquid crystal layer is almost the same, with a contrast of light and dark. However, when the crystal display panel of this patent JP-A-8 (1 996) -1 5708 will not tilt the screen from the horizontal plane, using the above-mentioned liquid will cause the following inconveniences as described below.

When using the aforementioned makeup-breaking eight-compensation car B, the eight-blade plus four saddle-shaped knife spacers such as plastic balls, etc., as its hardware separation report, the child should not be present; t; It cannot be fixed between two transparent substrates under the plate, and the difference in proportion between P ^ and the liquid crystal display is recognized by Fangkou Hairi and the hardware, and the liquid crystal display is used. The function of the partition moves with the liquid crystal layer, resulting in a clever: "After the hard partition in Tian Tian's liquid crystal display panel is made of Qiao Tian's knife cloth under high temperature, when the temperature returns to normal temperature, the board may produce Irregularity caused by irregular distribution.

In the case of S, when the columnar resin partition is used as a hard partition, since the bottom surface of the columnar resin partition is adhered to the transparent substrate, peeling of the partition can be avoided. However, in this case, since the crystal display panel is tilted, the pressure of the liquid crystal display panel on the transparent substrate becomes larger, and the bottom of the liquid crystal display panel becomes larger, and the bottom surface is subjected to the greatest pressure. Therefore, the liquid crystal at the bottom of the liquid crystal panel, due to the above-mentioned high pressure,

Page 7 567381 V. Description of the invention (4) Force the transparent substrate to move outward. As the distance between the two transparent substrates increases, part of the liquid crystal moves downward, reducing the potential energy of the liquid crystal. And the downward movement of this part of the liquid crystal 'shortens the distance between the two transparent substrates on the upper part of the liquid crystal display panel, and increases the compression force applied to the partition part of the part. It can be understood that the small amount of potential energy of the liquid crystal is consumed by the deformation of the combination elements of the liquid crystal display panel other than the liquid crystal, such as the aforementioned transparent substrate and partition. The top and bottom of the page are separated by the thermal & separation denaturation amount. The above-mentioned plate separation is also caused by the failure to increase the% image. 7 The expansion of the opposite side of the liquid crystal display is left small in the part and the separation between the two partitions is not included. Gauge, the deformed substrate of the liquid image quality display board is separated. The probability is a small amount of elasticity under the pressure generated by the temperature. The distance between the substrate and the substrate separation part no longer has the principle of maintaining the distance. As the crystal layer becomes thicker, it deteriorates. This extremely high separation causes the increase in compressive permeability. Maintaining the spacing of the elements allows the partitions to exceed the bottom of the LCD panel by less than at room temperature. This is due to the distance between the substrates. In the case of the remaining bomb, the partition has the functions of its top and phase, and the liquid crystal liquid crystal layer is unevenly distributed, and the relative limit of the substrate is allowed, because the state is increased, the sexual obliqueness is easily humiliated; I plate The bottom is even and the $ S

V. Description of the invention (6) A specific distance is maintained; a sealing frame is used to join the transparent substrates together; and a liquid crystal is used to fill the gap between the transparent substrate and the sealing frame; the transparent substrate is horizontal along the upright state. Bend in direction. According to the aforementioned second aspect of the present invention, since the transparent substrate is bent in the horizontal direction ', its resistance to bending around the horizontal axis direction is improved, and a structure that is not easily deformed is provided. The above-mentioned objects, features and advantages of the present invention will be made clearer by the following description. [Preferred embodiment of the present invention] The present invention will be further described with reference to the drawings. 1 An embodiment As shown in FIG. 1A, a first implementation plate (or a transparent glass substrate) 11 and a partition 14 are provided. The liquid crystal 15 fills the gap of the sealing frame 13 and fills the substrates 11 and 12 with a liquid crystal injection port, as shown at ordinary temperature. The aforementioned columnar resin partitioning portion 1 4 12 刖 'passes through the completion portion shown in Fig. 1B. The columnar resin shown in Figure 1B is compressed in the vertical direction and has been deformed elastically) and stored elastically. A certain amount of elastic deformation is erected at this stage, so that one of the examples of the liquid crystal display panel includes a transparent base 12 ′, a sealing frame 13 and a columnar resin divided into a space around the columnar resin partition 14 (not shown). The two transparent elements are combined to form the liquid crystal display panel. As shown in FIG. 1 β, the columnar resin separation partition 14 of the liquid crystal display panel that combines the transparent substrate 11 and the liquid crystal display panel is located along the transparent glass brick substrate 1 丨. In order to generate an assembly stress (or should initially be 'to the aforementioned columnar resin partitions 丨 4 to build the columnar resin partitions 丨 4 and 567381 V. Description of the invention (7) —— *' —- Ming substrate The direction is elastically compressed and deformed. Its position is when the liquid crystal display panel is tilted along the horizontal plane at the highest temperature of its operating temperature range. The distance between the two transparent substrates is the largest. ^ Figure 1B The completed state is shown. The columnar partition 14 may be located in the elastic region or the plastic region. The height of the partition 14 in the elastic region is restored to its natural length (original length) after applying a force other than the halving: two, j ; Wide: shown. Located in the plastic area The length of the partition 14 recovered after removing the external force applied to the partition is the natural length (or original length) minus the amount of plastic deformation, as shown in FIG. 1A, because the partition has been plastically deformed. In any case, the distance between the bright substrates and the total length of the sexual deformation in the completed state shown in FIG. 1B is greater than the maximum temperature of the liquid crystal display panel in the use temperature range g, when the display screen is inclined along the horizontal plane. The maximum distance is still long. Actually, this plastic deformation is very likely to occur, and it promotes shape hardening to make it a favorable condition for forming a strong liquid crystal display panel structure, making it difficult to deform. However, due to the plastic deformation of the partition, the After removing the external force applied to it, the length of the partition can not be restored to the natural length (original length) as shown in the figure. Therefore, the amount of elastic deformation and plastic deformation must be properly adjusted to establish the reconstruction. The attributes of the grid, such as: coefficient of elasticity, elastic limit, and breaking stress; & total surface area of the partition and the transparent substrate, the length of the partition; two transparent substrates Allowable range pitch, the package stress, and the liquid crystal display temperature range plate to effectively elastic deformation and plastic deformation of the advantage of using. In the state shown in FIG. 1C 'of the liquid crystal r text crystal display panel 15 upon completion of the

567381 V. Description of the invention (8) The liquid crystal 15 is heated to a high temperature, and the distance between the two transparent substrates 11 and 12 is increased due to thermal expansion. However, since the columnar resin partition 14 of the liquid crystal display panel of the first embodiment has an assembly stress (initial stress), the increased distance is relatively compared with a liquid crystal display panel without assembly stress in the resin partition. Decrease. In other words, in a specific elastic body having the aforementioned assembly stress, an external force required to generate an equivalent deformation is larger than that of the specific elastic body in its natural state. In other words, an elastomer with assembly stress is more resistant to deformation. -Therefore, compared with a liquid crystal display panel without assembly stress, the liquid crystal display panel shown in FIG. 1C has a large resistance to structural deformation, because a liquid crystal display panel without assembly stress needs a large external force to achieve the same Deformation. The state shown in FIG. 1D is that the liquid crystal display panel of FIG. Ic is inclined with respect to the horizontal plane. The length of the space occupied by the liquid crystal 15 in the direction of gravity is longer than that of the liquid crystal display panel in which the original image icf is not horizontal, and The internal pressure of the liquid crystal 15 f at the lower position also increases. As the internal pressure of the liquid crystal increases, the distance between the transparent substrates 11 and 12 on the lower half of the liquid crystal display panel also increases, and the $ ^ 1 5 also follows the transparent substrates 11, 1 on the half of the liquid crystal display panel. The pitch of 2 becomes narrower and the whole moves downward. Therefore, the maximum pitch is formed near the bottom surface of the display screen. reward

V. Description of the Invention (9) When the above-mentioned columnar resin partition 14 does not have or has insufficient assembly stress, the top end of the columnar resin partition 14 is peeled off from its opposite substrate 12 so that the distance between the two transparent substrates Beyond the limit, it may cause irregular development. However, since the top end of the columnar resin partition 14 in the state shown in FIG. 1D does not peel off from the substrate 12, and its assembly stress is also generated, resistance is higher than that of the [(^ plate, which has no assembly stress. Increasing or shortening the substrate pitch is relatively reduced. Therefore, the irregular display caused by the substrate pitch exceeding the limited range is expected to be reduced.

Accordingly, even in the liquid crystal display panel described in the first embodiment, the length of the liquid crystal in its gravitational direction caused by the liquid crystal display panel being subjected to thermal energy to change the internal pressure, or the liquid crystal display panel may be tilted or erected. In the case that the internal liquid pressure of the liquid crystal changes, the deformation amount of the liquid crystal structure (the transparent substrate, the partition, and the sealing frame other than the liquid crystal) can be reduced. The smaller the amount of deformation of the substrate structure, the smaller the distance change between the transparent substrates, and the change of the liquid crystal lamination is suppressed, thereby eliminating the traditional near the bottom of the display screen, especially when the screen is tilted. The irregular appearance occurred. Furthermore, since the top end of the partition is not separated from the opposite substrate 12, the partition is used as its gap fixing member (Jthe gap retaining members). In the figure (1A) for maintaining the liquid crystal layer, the column Length (height) of the resin-like partition

For example, when the distance between the two transparent substrates 11 and 12 is 4 // m, the actual value of the natural length of the partition is set to about 4. 1 // m or so. The difference between the liquid crystal display panel of the second embodiment and the liquid crystal display panel of the first embodiment lies in that the height of the columnar resin partition 4 must be set higher than that of the sealing frame 1 3 '. The generated bending stress remains in the transparent substrates 丨 and 12. The height of the sealing frame 13 can be set lower than the natural height of the columnar resin partition 14 before compression, or set to be close to, slightly higher or lower than the natural height of the columnar resin partition 丨 4 _ And the height after compression is higher than the above-mentioned columnar resin partition 14. As shown in FIG. 2B, the height of the sealed frame 13 in the aforementioned completed state is set to be higher than the columnar resin partition, so that the bending stress generated by the assembly remains in the transparent substrates 丨 丨 and 丨 2. Regardless of the method, the aforementioned transparent substrates 丨 丨 and 丨 2 are deformed by the momentary bending generated during assembly at normal temperature, causing the concave and convex outward, and the aforementioned assembly stress (initial stress) is introduced into the transparent substrates 11 and 1 2 Inside. In order to set and maintain the height of the aforementioned sealing frame 13, the material selected for the sealing frame must be strong enough to maintain the set height. However, solid materials such as glass and plastic can be mixed into the sealed frame. In the liquid crystal display panel of the second embodiment, the assembly stress generated in the columnar resin partitions 4 and the transparent substrates 11 and 12 is larger than that in the first embodiment.

Page 14 567381 V. What was produced in the description of the invention (11) can more restrain the increase of the distance between the transparent substrates 11 and 12 and thus prevent the occurrence of display unevenness. Next, an example of the manufacturing method of the aforementioned liquid crystal display panel is proposed (third, fourth, and fifth embodiments)

In the manufacture of the above-mentioned liquid crystal display panel, one electrode generally required for a liquid crystal display system and two transparent substrates with a hard film are combined together in a bonding step (assembly and sealing step). After the bonding step, the liquid crystal is injected into the liquid crystal display panel according to a liquid crystal injection step '. A vacuum evacuation method is used as a general liquid crystal injection method. When a vacuum element having a liquid crystal injection port and a liquid crystal display panel buried thereon is evacuated, the liquid crystal display panel is immersed in A liquid crystal container filled with liquid crystal is injected into the liquid crystal display panel when the pressure gradually increases. After the liquid crystal injection step, an injection port sealing step seals the liquid crystal injection port. In the process of sealing the injection port, the step of applying pressure to the substrate may be referred to as a pressurizing injection port sealing step.

The liquid crystal display panel shown in FIGS. 1B and 2B can be manufactured according to the following procedure. Fixed = two transparent substrates are connected, and the sealing frame 13 is also ΗΓΜ page 15 567381 V. Description of the invention (12) Through the sealing frame 1 3, the liquid crystal display panel having the liquid crystal injection port is placed in the aforementioned vacuum element "The space between the transparent substrate 丨 丨 and ^ in the liquid crystal display panel" is evacuated to a vacuum state by a vacuum evacuation device connected to the aforementioned vacuum element. The aforementioned liquid crystal container containing liquid crystal was placed in the vacuum element, and the liquid crystal injection port was immersed in the liquid crystal in the liquid crystal container. In this case, the internal pressure of the vacuum element is gradually increased to close to the atmospheric pressure. 'Thus the pressure difference between the inside of the liquid crystal display panel and the inside of the vacuum element' continuously injects the liquid crystal into the aforementioned liquid crystal display panel until the pressure on both sides reaches equilibrium. until. It takes about 100 hours to fill the space around the transparent substrate and the sealing frame in the 4 liquid crystal display panel. The aforementioned pressure injection port sealing step is performed when the space around the transparent substrate and the sealing frame is filled with liquid crystal. By applying external pressure to the transparent substrates 丨 i, 丨 2, the transparent substrates 11 and 12 are bent and deformed, and the columnar resin partitions 14 are also compressed and deformed. At this stage, the liquid crystal in the LCD panel is discharged. Thereafter, the sealing material of the injection port such as a thermosetting epoxy resin is placed in the liquid crystal injection port, or the sealing material of the injection port is placed in the liquid crystal injection port by slightly reducing the pressure applied to the two transparent substrates. It is considered that the elastic deformation of the aforementioned columnar resin partition is restored due to pressure reduction. The pressure of the seal 5 is adjusted so that the distance between the two transparent substrates 11 and 12 reaches a desired value. The injection port sealing material is then cured. By controlling the amount of elastic deformation of the columnar resin partitions 14 and the amount of elastic deformation caused by the bending deformation of the transparent substrates 11 and 12, it is possible to obtain graphs ^ and 567381

Before the space around the soil u, 12 and the sealing frame 13, the aforementioned liquid stomach filling step has been completed. In other words, the injection amount of the liquid crystal is adjusted so that its capacity is smaller than the internal space of the sealed frame 13 and the space capacity from the surface of the transparent substrate 11 to the top of the ridge-shaped tree partition 14 (hereinafter referred to as "original capacity"). ”) ° The liquid crystal discharged by reducing the original capacity in the third embodiment, when the discharged residual liquid crystal is injected into the aforementioned vacuum element, the liquid crystal injection step is completed, and the aforementioned pressure injection port sealing step is started. Through the internal volume of the transparent substrates 11 and 12, the transparent resin-like resin partitions 14 are also pressed inside the volume of the display panel. Due to the aforementioned original capacity, no liquid crystal is discharged, and only a small amount of liquid crystal is injected from the liquid crystal. An external pressure reduces the liquid crystal substrates 11 and 12 to be deformed by bending and shrinking. Although the injection amount of the liquid crystal display has been reduced, it has been adjusted to less than. If liquid crystal discharge occurs, the mouth overflows. After that, the inlet

Considering the elastic deformation of the columnar resin partition, the pressure is reduced to return to the original state. The magnitude of the sealing pressure is adjusted so that the distance between the two transparent substrates 11 and 12 reaches a desired value. The injection port sealing material is then cured. By controlling the deformation amount of the columnar resin partitions 4 and the amount caused by the bending deformation of the transparent substrates 11 and 12, the liquid crystal display panel shown in FIGS. 1B and 2B can be obtained.

At this stage, the columnar resin partition 14 is in its natural state and has a natural length. The amount of the dropped liquid crystal is adjusted so that its capacity is smaller than the internal space of the sealed frame 3, the space capacity (original capacity) from the surface of the transparent substrate 11 to the top end of the columnar resin partition 14 in the natural state. This is because the amount of liquid crystal released during the plate pressing step described below is minimized to shorten the length of time to add the liquid crystal, and because the volume of the completed state is smaller than the original volume, the amount of The burden of stress and release.

In fact, in order to ensure its display quality, the partition is arranged on a light shield around the color pixels. According to the liquid crystal display panel of this embodiment, the number of partitions in the display area can be reduced to one-third to two-thirds of the number of color pixels, and the partitions are neatly arranged on the transparent substrate.
