Description

  The present invention relates to a liquid crystal display element having a wall frame-like seal spacer and a method for manufacturing the same.

  In recent years, an image display module using a flat display panel (hereinafter referred to as FPD (Flat Panel Display)) such as a liquid crystal display panel or an organic electroluminescence display panel is advantageous in reducing the thickness of an applied device. It is widely used as a display for mobile devices such as PDAs (Personal Digital Assistance). However, the demand for miniaturization and thinning is extremely strict for displays of mobile devices, and further miniaturization and thinning are demanded for FPD modules.

In downsizing the outer shape of the FPD, it is desired to reduce a so-called frame area around the display area. Therefore, it is required to reduce the arrangement area of the frame-shaped sealing material that forms the frame.
In particular, in a liquid crystal display panel in which liquid crystal is sealed inside, a frame-shaped sealing material for sealing liquid crystal is applied to one of a pair of substrates to be bonded using a method such as screen printing as shown in Patent Document 1. It is applied in a frame shape surrounding the display area, and then the other substrate is bonded and thermocompression bonded to crush the sealing material to obtain the desired substrate gap. At this time, since the sealing material is applied thicker than the substrate gap to be obtained and crushed, the actual sealing width becomes larger than the width of the sealing material applied. Therefore, an area for allowing the seal material to protrude is provided between the display area and the application area of the seal material so that the pressed seal material does not protrude into the display area when the pair of substrates are bonded by pressure bonding. An undulation control pattern of the seal material that is provided or crushed is provided.

Can do.

  FIG. 1 is a plan view showing a liquid crystal display panel as one embodiment of the present invention, FIG. 2 (a) is an enlarged plan view of a main part of FIG. 1, and FIG. 2 (b) is a sectional view taken along line BB. It is a typical sectional view shown.

  The liquid crystal display panel of the present embodiment is a simple matrix type liquid crystal display panel. As shown in FIGS. 2A and 2B, one transparent glass substrate 1 has a plurality of stripe-shaped display electrodes 2. Are arranged in parallel, and the alignment film 3 is uniformly deposited so as to cover them.

  A black matrix 5 is provided on the other glass substrate 4 disposed to face the glass substrate 1. In the black matrix 5, a plurality of rectangular openings 51 corresponding to each pixel are formed in a matrix arrangement. A plurality of stripe-shaped color filters 6 are provided along the arrangement of the openings 51 in the column direction (the direction perpendicular to the paper surface). The color filter 6 includes red, green, and blue color filter bands 6r, 6g, and 6b. The color filter bands 6r, 6g, and 6b are arranged in parallel in a predetermined order corresponding to the row-direction arrangement of the openings 51. Yes.

  A flattening protective film 7 is uniformly applied to the color filter 6 over almost the entire area of the color filter 6, and a plurality of striped scanning electrodes 8 are formed on the flattening protective film 7 in the row direction of the openings 51. They are arranged in parallel along the arrangement. An alignment film 9 is uniformly provided so as to cover the scanning electrode 8.

  The glass substrates 1 and 4 described above are bonded by the frame-shaped sealing material 10 in such an arrangement that the display electrodes 2 are aligned with the corresponding color filter bands 6r, 6g, and 6b on the opposite side with the electrode forming surfaces facing each other. Yes. In the liquid crystal display cell thus obtained, a display region D1 is formed in which a plurality of pixels corresponding to the openings 51 of the black matrix 5 are arranged in a matrix at the opposing portion of the display electrode 2 and the scanning electrode 8, and this display region A peripheral region D2 in which the frame-shaped sealing material 10 is installed is formed in a frame shape so as to surround D1.

  Here, the width Wf of the peripheral region D2 indicating the frame width in the display element is a buffer area for allowing the seal material to protrude in the substrate bonding step to the width Ws of the frame-shaped seal material 10 (hereinafter referred to as seal width). It is set in anticipation of the width Wb. The dimension of the seal width Ws is set to a size that can sufficiently secure the necessary substrate bonding strength and the barrier property against moisture permeation into the liquid crystal sealed inside, that is, moisture resistance.

  The pair of glass substrates 1 and 4 joined by the frame-shaped sealing material 10 are provided with a plurality of spherical in-plane spacers 11 in the display area D1 and a plurality of cylindrical seal spacers 12 in the peripheral area D2. Thus, a gap between predetermined substrates is secured.

  The in-plane spacers 11 are evenly distributed and distributed over the entire display area D1, and the seal spacers 12 are arranged in a plurality of positions in the peripheral area D2 at regular intervals and in a triple concentric frame shape in this embodiment. Has been.

  In the peripheral region D2, first and second line spacers 13a and 13b having a wall frame shape are arranged in a double concentric frame. The first and second line spacers 13a and 13b are disposed in a region (hereinafter referred to as an inner peripheral region) D2i on the display region D1 side with the width center line L1 in the peripheral region D2 as a boundary line. The height h of the first and second line spacers 13a and 13b is set to the same dimension as the height of the seal spacer 12, that is, the substrate gap d to be obtained.

  The first and second line spacers 13a and 13b are provided to restrict the substrate gap in the peripheral region D2 and to prevent the seal material compressed during substrate bonding from extending toward the display region D1. ing. Therefore, by providing the first and second line spacers 13a and 13b, the buffer area can be set as small as possible. As a result, the width Wf of the peripheral region D2 is narrowed, that is, the frame is narrowed. It becomes possible.

  Here, a specific configuration example such as the size of each part of the seal portion in the liquid crystal display panel of the present embodiment will be described.

  The substrate gap d (spacer height h) that determines the liquid crystal layer thickness is 5 μm, and the sealing material 10 is made of epoxy resin as a material, and the sealing width Ws is set to 700 μm in order to ensure the necessary substrate bonding strength and moisture resistance. The first and second line spacers 13a and 13b are made of acrylic resin having excellent moisture resistance, and are erected from the center line L1 in the width direction of the peripheral region D2 at a distance R1 = 100 μm and a distance R2 = 150 μm, respectively. To do. Thereby, the width Wb of the buffer area can be set as small as about 300 μm, and the width Wf of the peripheral region D2 becomes 1000 μm.

  As shown in FIG. 1, an opening 101 for injecting liquid crystal is provided in the sealing material 10 so as to penetrate in the width direction. Accordingly, also in the first and second line spacers 13a and 13b, portions corresponding to the liquid crystal injection openings 101 are cut off. After the liquid crystal is injected into the space surrounded by the frame-shaped sealing material 10 and the pair of glass substrates 1 and 4 from the liquid crystal injection opening 101, the liquid crystal injection opening 101 is sealed, as shown in FIG. A liquid crystal display panel in which the liquid crystal 14 shown is sandwiched between a pair of glass substrates 1 and 4 is obtained.

  Next, steps according to the present invention in the method for manufacturing a liquid crystal display element of the present embodiment will be described with reference to FIGS.

  First, the seal spacer 12 and the first and second line spacers 13a and 13b are erected on the assembly of the pair of glass substrates 1 and 4 on which the electrodes 2 and 8 and the alignment films 3 and 9 have been formed. Here, the first and second line spacers 13a and 13b are erected on different glass substrates 1 and 4, respectively.

  In this embodiment, as shown in FIG. 3A, the second line spacer 13b and the seal spacer 12 are erected on the glass substrate 1 on which the display electrode 2 is installed, and the glass substrate 4 on which the color filter 6 is installed. The first line spacer 13a is erected. A large number of in-plane spacers 11 are evenly distributed and arranged in one of the display regions D1 of the glass substrate 4, for example.

  Next, a material (sealing material) 10a for forming a sealing material made of a thermosetting epoxy resin material is located at a position 150 μm away from the second line spacer 13b on the glass substrate 1 or on the glass substrate 4 at the first position. It is applied in a frame shape with a position P about 100 μm away from the one-line spacer 13a as the center. The application position P is a position away from the display area D1 by about 500 μm and coincides with the width center line L1 of the peripheral area D2. When applying the seal material 10a, the seal material 10a is raised to a height H of, for example, about 20 μm, which is higher than the height h of the seal spacer 12 and the line spacers 13a and 13b, by a screen printing method or a dispenser method. To do.

  Next, the glass substrates 1 and 4 are bonded together while aligning the assembly of both glass substrates 1 and 4 so that the surface on the electrode forming side faces each other and the display electrode 2 faces the corresponding color filter bands 6r, 6g and 6b. Then, while heating the assembly in which the glass substrates 1 and 4 are bonded together with a thermocompression bonding apparatus, the spacers 12, 13a, 13b and 11 are pressurized until they abut against the opposing substrate, The state in which 13a, 13b, and 11 are sandwiched between the pair of glass substrates 1 and 4 is held for a certain time, and the epoxy resin of the sealing material 10a is thermally cured. Thereby, the thermocompression bonding process of the glass substrates 1 and 4 is completed.

  In the above-described thermocompression bonding process, the sealing material 10a disposed and applied is heated and softened while being sandwiched and pressed between the glass substrates 1 and 4 so as to be substantially uniformly rolled in the surface direction of the glass substrates 1 and 4. However, from the stage where the first and second line spacers 13a and 13b begin to overlap each other in the in-plane direction as shown in FIG. The first and second line spacers 13a and 13b become obstacles, and the extension thereof is suppressed, and the amount of material directed toward the substrate end face side, that is, the outside with less obstacles increases. As a result, as shown in FIG. 2B, the inward extending width Wsi from the application center position P of the sealing material is suppressed to about 200 μm, and the outward extending width Wso is formed to be about 500 μm. Then, the sealing material 10 having a total width Ws of 700 μm is formed in a frame shape. The frame-shaped sealing material 10 thus formed has a large total width Ws of 700 μm, and has sufficient substrate bonding strength and moisture resistance. In addition, since the buffer area width Wb of 300 μm is secured, the sealing material 10a does not extend to the display region D1 during the thermocompression bonding and does not adversely affect the display.

  As described above, in the liquid crystal display panel of the present embodiment, the wall frame-shaped first and second line spacers are formed in the inner peripheral region D2i from the width center line L1 of the peripheral region D2 surrounding the display region D1 to the display region D1. Since 13a and 13b are doubly arranged in the same frame shape surrounding the peripheral region D2, it is possible to effectively suppress the extension of the sealing material 10a toward the display region D1 during thermocompression bonding. As a result, the wide sealing material 10 having sufficient required substrate bonding strength and moisture resistance can be disposed stably without always extending to the display region D1. Thus, the buffer area for absorbing the variation in the degree of extension of the sealing material during thermocompression can be set as small as possible to promote the narrowing of the peripheral region D2, that is, the narrowing of the liquid crystal display element. it can.

  Further, according to the method of manufacturing the liquid crystal display panel of the present embodiment, the first and second line spacers 13a and 13b are separately provided on the separate glass substrates 1 and 4, respectively. The extension of the sealing material toward the display region D1 can be more effectively suppressed. As a result, the buffer area can be set to be further reduced, and the narrowing of the frame of the liquid crystal display element can be further promoted.

  Next, another embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the component same as the said embodiment, and the description is abbreviate | omitted.

  The liquid crystal display panel of this embodiment is obtained by joining a large-area glass substrate to form a large number of liquid crystal display cells, and separating the assembly along a scribe line. Therefore, if the sealing material extends to the scribe line, the process of separating into individual liquid crystal cells is hindered. For this reason, conventionally, a buffer area is secured not only between the sealing material 10 and the display area but also between the substrate end face to absorb variations in the degree of extension of the sealing material. Was getting wider.

  Therefore, in the liquid crystal display panel of this embodiment, as shown in FIG. 4A, the first and second line spacers 20a and 20b are moved from the width center line L1 of the peripheral region D2 to the substrate end face line, that is, the scribe line L2. A double concentric wall frame surrounding the display area D1 is provided in the area (hereinafter referred to as the outer peripheral area) D2o.

  Specifically, in the liquid crystal display panel including the peripheral region D1 having a total width Wf of 1000 μm, the first line spacer 20a is positioned 300 μm away from the width center line L1, and the second line spacer 20b is positioned outward. They are respectively erected at positions separated by 50 μm (350 μm outward from the width center line L1). The width Wb1 of the inner buffer area for absorbing the variation in the degree of extension of the seal material toward the display region D1 is 200 μm, and the width Wb2 of the buffer area for absorbing the variation in the degree of extension toward the substrate end surface. Is set to 100 μm. Other configurations are substantially the same as those in the above embodiment.

  In the method of manufacturing the liquid crystal display panel according to this embodiment, as shown in FIGS. 5A and 5B, the glass substrate on which the display electrode 2 is installed is used as the first line spacer 20a as in the case of the above embodiment. First, the second line spacer 20b is erected on the glass substrate 4 on which the color filter 6 is installed in a wall frame shape surrounding the display area D1. Then, the application center position P of the sealing material is set at a position 200 μm away from the width center line L1, and the sealing material is placed at any one of the positions P of the glass substrates 1 and 4 by screen printing, for example, about 20 μm. Apply to a height H of. Thereafter, thermocompression bonding is performed in the same manner as in the above embodiment.

  In the above-described thermocompression bonding process, the applied sealing material is heated and pressed to be rolled along the substrate surface direction. As shown in FIG. 5B, the first and second line spacers are used. From the stage where 20a and 20b start to overlap each other in the in-plane direction, the first and second line spacers 20a and 20b become obstacles to the material facing the substrate end face side, that is, the outside, and the extension thereof is suppressed. , The amount of material going to the display area D1 side with less obstacles, that is, the inside increases. As a result, as shown in FIG. 4B, the outward extending width Wso from the application center position P of the sealing material is suppressed to about 200 μm, and the inward extending width Wsi is formed to be about 500 μm. Then, the sealing material 10 having a full width W of 700 μm, which is sufficiently provided with the necessary substrate bonding strength and moisture resistance, is formed in a wall frame shape.

  In this case, since the extension of the sealing material to the outside is suppressed by the first and second line spacers 20a and 20b, the sealing material is used for the scribe line L2 even if the width Wb2 of the outer buffer area is set smaller than the conventional one. The problem of extending to a certain level is reliably prevented, and separation into individual liquid crystal cells in the scribe process is always performed smoothly.

  In addition, since the application center position P of the seal material is set to a position away from the width center line L1 of the peripheral region D2 by Δa (200 μm in this embodiment), a line that suppresses the extension of the seal material to the inside. Even if the width Wb1 of the inner buffer area is set to 200 μm, which is smaller than that in the above embodiment without providing a spacer, the sealing material does not extend to the display area D1 and the problem of impairing display quality does not occur.

  As described above, in the liquid crystal display panel of this embodiment, the wall frame-shaped first and second line spacers 20a are arranged in the outer peripheral region D2o extending from the width center line L1 of the peripheral region D2 surrounding the display region D1 to the substrate end surface. , 20b are arranged in a double concentric frame shape, the extension of the sealing material toward the substrate end face during thermocompression bonding can be effectively suppressed. As a result, the wide sealing material 10 having sufficient required substrate bonding strength and moisture resistance can always be stably disposed without extending to the end surface of the substrate. As a result, the width Wb2 of the outer buffer area for absorbing the variation in the degree of extension of the sealing material toward the substrate end face during thermocompression bonding is set as small as possible to narrow the peripheral region D2, that is, the liquid crystal display element. Narrowing of the frame can be promoted.

  In addition, since the seal material is reliably prevented from extending to the scribe line L2, the work for separating each liquid crystal cell from the large-area substrate assembly is always performed smoothly, and the number of manufacturing steps for the liquid crystal display panel is reduced. Reduced.

  Furthermore, since the application center position P of the sealing material is shifted by 200 μm outside the peripheral area width center line L1, the distance between the application center position P and the display area D1 is enlarged by the shift width, and a line spacer is provided between them. Even if not, the width Wb1 of the inner buffer area for absorbing the variation in the degree of extension toward the display area D1 can be set smaller than the conventional one, and the outward extension by the first and second line spacers 20a and 20b. In combination with the suppression effect, it is possible to further promote the narrowing of the frame.

In addition, this invention is not limited to said embodiment.
For example, the paired wall frame-shaped line spacers may be provided on both sides of the width center line of the peripheral region. In this case, the sealing material that is thermocompression bonded in the thermocompression process is in a state of being sandwiched between the line spacers, and the phenomenon that bubbles are trapped in the sealing material is likely to occur. It becomes difficult to ensure adhesive strength and moisture resistance. However, this can be realized by accurately controlling the amount of the sealing material applied so as not to trap the bubbles.

  The wall frame-shaped line spacer may be formed with an appropriate number of through-holes with an appropriate size and density within a limit in which a required effect of suppressing the extension of the sealing material is ensured. As a result, the above-described bubble trap can be more reliably prevented.

  Furthermore, the wall frame-shaped line spacer is not limited to a pair, and three or more wall frame-shaped line spacers may be provided.

  Furthermore, it goes without saying that the manufacturing method of the present invention can also be applied to a manufacturing method that employs a method of enclosing liquid crystal simultaneously with substrate bonding. In this case, there is no need to provide a liquid crystal injection port in the sealing material, and the installation of the wall frame-shaped line spacer of the present invention is facilitated.

  In addition, the present invention is not limited to the simple matrix type liquid crystal display element, and can of course be widely applied to other various liquid crystal display elements such as an active matrix type.
