Description

  The present invention provides a liquid crystal display comprising a display liquid crystal panel having a polarizing plate pasted on the back surface, and a panel member pasted through an adhesive layer provided to embed the polarizing plate on the back surface. Relates to the device.

  Since two human eyes are located spatially apart in the head, they perceive images viewed from two different viewpoints. Then, the human brain recognizes the three-dimensional effect based on the parallax between these two images.

  Utilizing this principle, a liquid crystal display device has been developed that gives a parallax by visually recognizing an image viewed from different viewpoints on the left and right eyes of an observer and performs 3D display (stereoscopic 3D display).

  In such a liquid crystal display device, as a technique for supplying images of different viewpoints to the left and right eyes of an observer, for example, a left eye image and a right eye image encoded according to color, polarization state, or display time are displayed on a screen. Some display above and provide images corresponding to the left and right eyes by separating them with a spectacle-like filter system worn by an observer.

  In addition, by combining the display liquid crystal panel with a parallax barrier in which light transmission regions and light blocking regions are alternately formed in stripes, each of the right-eye image and the left-eye image displayed on the display liquid crystal panel is displayed. On the other hand, a specific viewing angle is given by a parallax barrier, and if it is from a specific observation area in the space, images corresponding to the left and right eyes are visually recognized, and the observer uses a visual aid such as a filter system. There is also a technology that makes it possible to recognize a 3D display without having to.

  A liquid crystal display device provided with such a parallax barrier is disclosed in Patent Document 1. In Patent Document 1, a configuration using a patterned retardation plate as a parallax barrier is disclosed.

  Patent Document 2 discloses a liquid crystal display device that can electrically switch between 3D display and 2D display (planar display) by configuring a switching liquid crystal layer or the like as a means for switching the parallax barrier function between valid and invalid, That is, a liquid crystal display device that performs 3D display when the function of the switching liquid crystal layer is enabled and performs 2D display when the function of the parallax barrier is disabled is disclosed.

  As described above, a technique for performing 3D display by combining a display liquid crystal panel and a parallax barrier is known.

  Patent Document 3 describes a liquid crystal display device capable of 2D display and 3D display as described above, that is, a 2D / 3D switching type liquid crystal display device, which is patterned with a display liquid crystal panel using TFTs or the like. And a switching liquid crystal panel including a parallax barrier is disclosed.

The above-mentioned 2D / 3D switching type display liquid crystal panel composed of two panels, a display liquid crystal panel and a switching liquid crystal panel, is obtained by bonding these panels with an adhesive such as an ultraviolet curable resin or a double-sided tape. It has become. However, the allowable range of the alignment accuracy of the bonding between the display liquid crystal panel and the switching liquid crystal panel is about ± 5 μm. For example, 3D display is not realized if the display liquid crystal panel deviates by 10 μm or 20 μm. When a double-sided tape is used, it is not possible to adjust the position after bonding, and therefore it is necessary to adjust the position before bonding. On the other hand, when an ultraviolet curable resin is used, the alignment can be adjusted after being bonded, and then the adhesive can be completed by irradiating and curing the ultraviolet rays. In a high temperature environment, the one using an ultraviolet curable resin is more reliable than the one using a double-sided tape. Therefore, in general, the display liquid crystal panel and the switching liquid crystal panel are bonded to each other via an adhesive made of an ultraviolet curable resin, and the two panels are bonded together by irradiating ultraviolet rays from the outside after alignment and curing the adhesive. That is done.
Japanese Patent Laid-Open No. 10-229567 (released on August 25, 1998) Japanese Patent Laid-Open No. 10-123461 (published on May 15, 1998) Japanese Patent Laid-Open No. 3-119889 (published on May 22, 1991)

  Incidentally, as shown in FIG. 4, when the switching liquid crystal panel 120 ′ is bonded to the display liquid crystal panel 110 ′, the polarizing plate 115 ′ is attached to the adhesive surface on the back surface of the display liquid crystal panel 110 ′. A thin central portion (region a) corresponding to the polarizing plate 115 ′ and a thick outer peripheral portion (region b) corresponding to the outer side of the polarizing plate 115 ′ are formed in the adhesive layer 130 ′ between both panels. It will be.

  For example, specifically, a display liquid crystal panel having a 250 μm-thick polarizing plate pasted on the back surface and a switching liquid crystal panel are bonded together with an ultraviolet curing adhesive, and at the center portion corresponding to the polarizing plate at that time When the thickness of the adhesive is 50 μm, the thickness of the adhesive at the outer peripheral portion corresponding to the outside of the polarizing plate is 300 μm (250 μm + 50 μm).

  When this is irradiated with ultraviolet rays, a phenomenon occurs in which different cured states are formed in the central portion having an adhesive thickness of 50 μm and the outer peripheral portion having an adhesive thickness of 300 μm. When such a phenomenon occurs, it acts on the display liquid crystal panel 110 ', thereby affecting the thickness of the liquid crystal cell and causing display unevenness in the peripheral portion of the screen, resulting in extremely low display quality. This is particularly remarkable in a transflective display type liquid crystal display device that is sensitive to changes in the thickness of the liquid crystal cell and easily causes display unevenness. In addition, the above-mentioned display unevenness is particularly noticeable in a high temperature and high humidity atmosphere, and there is a problem in the reliability as a liquid crystal display device.

  The present invention has been made in view of such points, and the object of the present invention is that even if a panel member is attached to the back surface of a display liquid crystal panel provided with a polarizing plate via an adhesive layer, An object of the present invention is to provide a liquid crystal display device in which the occurrence of display unevenness is suppressed.

  The reason why the central part with a small adhesive thickness and the outer peripheral part with a thick adhesive thickness are formed in different cured states is that the adhesive hardens quickly in the central part, but the hardened surface layer in the outer peripheral part. The inventors have found that this is because UV light, that is, light having a curing wavelength (especially short wavelength light having a wavelength of 365 nm or less) is inhibited from proceeding smoothly in the thickness direction. The present invention has been conceived. On the other hand, it is conceivable to increase the amount of ultraviolet light, but in that case, the difference between the two cured states is further enlarged, and a new problem of coloring occurs.

The present invention that achieves the above-described object is applied to a display liquid crystal panel having a polarizing plate pasted on the back surface, and an adhesive layer provided to embed the polarizing plate on the back surface of the display liquid crystal panel. A liquid crystal display device provided with a panel member,
The adhesive layer is made of a photo-curing resin that is cured with light having a predetermined wavelength, and the light absorption rate of the light with the predetermined wavelength is 5% or less.

  According to the above configuration, the light absorption rate of the adhesive layer, that is, the light having the curing wavelength of the cured photocurable resin is 5% or less. The influence of inhibition of progression is small. Therefore, if the difference in thickness is about 250 to 500 μm, the same cured state is formed in the central portion where the adhesive thickness is thin and the outer peripheral portion where the adhesive thickness is thick, and display unevenness occurs on the peripheral portion of the screen. Is suppressed. In other words, unlike the prior art, the cured state is different between the central portion and the outer peripheral portion of the adhesive layer, thereby preventing the liquid crystal cell thickness from being affected and causing significant display unevenness in the peripheral portion of the screen.

  Here, the light absorptance is calculated according to the equation of light absorptivity = 100−transmittance (%) from the light transmittance for each wavelength measured from the cured adhesive layer. Moreover, the light absorptance for every wavelength of light is proportional to content of the reaction initiator of the photocurable resin used as an adhesive agent.

  In the present invention, the adhesive layer preferably has an optical absorptance of 1% or more of the light having the predetermined wavelength.

  According to said structure, even if it receives the log | history in the atmosphere of high temperature and high humidity, an adhesive layer is not influenced.

  The predetermined wavelength as the curing wavelength of the photocurable resin is generally 365 nm.

  The present invention is particularly effective when the display liquid crystal panel is a transflective display type because it is sensitive to changes in cell thickness and display irregularities are relatively likely to occur.

  In the present invention, the panel member is not particularly limited, and examples thereof include a switching liquid crystal panel for switching between a two-dimensional display mode and a three-dimensional display mode.

  According to the present invention, since the light absorption rate of the light having the curing wavelength of the adhesive layer is 5% or less, if the difference in thickness is about 250 to 500 μm, the thickness of the adhesive and the thickness of the adhesive is small. The same hardened state is formed in the thick outer peripheral portion, and the occurrence of display unevenness in the peripheral portion of the screen can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited to the following embodiment.

  FIG. 1 shows a schematic configuration of a display panel module 100 of a 2D / 3D display switching type liquid crystal display device according to the present embodiment.

  The display panel module 100 includes a display liquid crystal panel 110 and a switching liquid crystal panel 120 attached to the back surface of the liquid crystal panel 110 via an adhesive layer 130.

  The display liquid crystal panel 110 is of an active matrix drive type, is provided so as to be opposed to each other, and a front-side counter substrate 111 and a back-side active matrix substrate 112, the periphery of which is bonded with a sealing material, And a liquid crystal layer 113 provided so as to be sandwiched between them.

  The counter substrate 111 is provided with a common electrode on the inner liquid crystal layer 113 side. Moreover, the 1st polarizing plate 114 is stuck by the center part of the front side which is an outer side.

  The active matrix substrate 112 is provided with a gate line and a source line so as to form a lattice on the inner liquid crystal layer 113 side, and a pixel electrode via a thin film transistor (TFT) as a switching element at each intersection. Is provided. In addition, a second polarizing plate 115 is attached to a central portion on the back side that is the outside. Further, a wiring board 140 such as an FPC (Flexible Printed Circuits) is connected, and a predetermined signal is sent to the gate line and the source line through the wiring board 140.

  The liquid crystal layer 113 is constituted by, for example, a TN (Twisted Nematic) liquid crystal layer.

  In this display liquid crystal panel 110, one pixel is defined by one pixel electrode, and for each pixel, the alignment state of the liquid crystal molecules of the liquid crystal layer 113 is modulated by an applied voltage between the pixel electrode and the counter electrode, The light transmittance is adjusted according to the image to be displayed. That is, the display liquid crystal panel 110 constitutes a display image generation unit for generating a display screen corresponding to the image data.

  The display liquid crystal panel 110 may be a transparent electrode in which each pixel electrode is made of ITO (Indium Tin Oxide) or the like, or a part of each pixel electrode is a transparent electrode and the other part is aluminum or the like. The electrode may be a reflective electrode formed by the above, that is, a transflective display type.

  FIG. 2 shows the switching liquid crystal panel 120.

  The switching liquid crystal panel 120 is provided so as to be opposed to each other and sandwiched between the front-side driving-side substrate 121 and the rear-side opposing substrate 122 whose peripheral edges are bonded with a sealing material. Liquid crystal layer 123.

  Each of the driving side substrate 121 and the counter substrate 122 is provided with a transparent electrode on the inner side of the liquid crystal layer 123. In addition, a third polarizing plate is attached to the counter substrate 122 on the back side which is the outside so that the transmission axis coincides with the second polarizing plate 115 of the display liquid crystal panel 110. Further, a wiring board 150 such as FPC (Flexible Printed Circuits) is connected, and a predetermined signal is sent to the transparent electrode through this.

  In the liquid crystal layer 123, stripes are alternately formed by an isotropic region 124 formed of a refractive index isotropic transparent resin and an anisotropic region 125 formed of liquid crystal having a refractive index anisotropy. It is provided as follows.

  The switching liquid crystal panel 120 transmits linearly polarized light transmitted through the third polarizing plate as it is in an isotropic region 124 formed of a refractive index isotropic translucent resin in the liquid crystal layer 123, but the refractive index is not changed. In the anisotropic region 125 formed of anisotropic liquid crystal, the alignment state of liquid crystal molecules is modulated by the voltage applied to the liquid crystal layer 123 to change the polarization state of linearly polarized light. Specifically, in the anisotropic region 125, when the liquid crystal molecules of the liquid crystal layer 123 are in parallel alignment or TN alignment, the liquid crystal molecules are applied to the substrate when a voltage is applied, and in the vertical alignment, no voltage is applied. Since the liquid crystal layer 123 rises, the refractive index anisotropy of the liquid crystal layer 123 does not affect the linearly polarized light, and the linearly polarized light transmitted through the third polarizing plate is transmitted as it is, as in the isotropic region 124. On the other hand, the refractive index anisotropy of the liquid crystal layer 123 affects the linearly polarized light when no voltage is applied when the liquid crystal molecules of the liquid crystal layer 123 are in parallel alignment or TN alignment, and when the voltage is applied in the case of vertical alignment, The linearly polarized light transmitted through the third polarizing plate is changed in polarization state and transmitted.

  In the above configuration, in the display panel module 100, when the polarization state of the linearly polarized light is not changed in the anisotropic region 125 of the switching liquid crystal panel 120, as shown in FIG. In addition, the linearly polarized light transmitted through any of the anisotropic regions 125 is incident on the display liquid crystal panel 110, and at that time, the same light reaches the left and right eyes of the observer, whereby a two-dimensional image is obtained. Has been observed. On the other hand, when the polarization state of the linearly polarized light is changed in the anisotropic region 125 of the switching liquid crystal panel 120, the linearly polarized light transmitted through the anisotropic region 125 is the second polarizing plate as shown in FIG. Since only the linearly polarized light that is shielded because it cannot pass through 115 and passes through the isotropic region 124 is incident on the display liquid crystal panel 110, different light reaches the left and right eyes of the observer at that time, and The viewing angle and the like are set so that the right eye image displayed on the display liquid crystal panel 110 is observed on the right eye and the left eye image displayed on the display liquid crystal panel 110 is observed on the left eye, respectively. As a result, a three-dimensional image is observed. That is, the anisotropic region 125 of the switching liquid crystal panel 120 constitutes a parallax barrier, and switching between two-dimensional display and three-dimensional display can be performed by switching this ON / OFF.

  The adhesive layer 130 between the display liquid crystal panel 110 and the switching liquid crystal panel 120 is provided so as to embed a second polarizing plate 115 attached to the central portion of the back surface of the display liquid crystal panel 110. The adhesive layer 130 is formed of a photocurable resin that is cured by light including light having a wavelength of 365 nm, and has a light absorption rate of 1 to 5% or less for light having a wavelength of 365 nm. The adhesive layer 130 irradiates light such as ultraviolet rays from the outside after applying and bonding a photocurable resin adhesive to the back surface of the display liquid crystal panel 110 and / or the front surface of the switching liquid crystal panel 120. It is formed by doing. As described above, since the adhesive is formed of the photocurable resin, the workability of the bonding operation between the display liquid crystal panel 110 and the switching liquid crystal panel 120 is extremely excellent.

  Such a display panel module 100 is housed in a case together with other components such as a driver and a backlight to constitute a 2D / 3D display switching type liquid crystal display device.

  According to the 2D / 3D display switching type liquid crystal display device having the above configuration, the adhesive layer 130, that is, the light absorption rate of the light having a wavelength of 365 nm of the cured photocurable resin is 1 to 5% or less. In the outer peripheral part where the thickness is thick, the influence of the inhibition of the light progression by the hardened surface layer is small. Therefore, if the difference in thickness is about 250 to 500 μm, the thickness of the adhesive and the central part where the adhesive is thin The same hardened state is formed in the thick outer peripheral part, and the occurrence of display unevenness in the peripheral part of the screen is suppressed. Moreover, it is not affected even if it is subjected to a history in an atmosphere of high temperature or high humidity. In particular, since such an effect is sensitive to changes in the thickness of the liquid crystal cell and easily causes display unevenness, the pixel electrode is formed of a transparent electrode and a reflective electrode, and the display liquid crystal panel 110 is a transflective display. It becomes prominent when it is a mold. Therefore, according to this, as in the conventional case, the cured state is different between the central portion and the outer peripheral portion of the adhesive layer, thereby causing the liquid crystal cell thickness to be affected and causing significant display unevenness in the peripheral portion of the screen. There is no.

  In addition, if the photocurable resin forming the adhesive layer 130 is visible light curable, the adhesive layer 130 is greatly changed over time, and if accompanied by a backlight, the reliability and display quality are greatly affected. According to the 2D / 3D display switching type liquid crystal display device having the above configuration, since the photocurable resin forming the adhesive layer 130 is visible light curable, it is possible to suppress a change with time of the adhesive layer 130 to be small.

  In the above embodiment, the switching liquid crystal panel 120 is pasted on the back surface of the display liquid crystal panel 110. However, the present invention is not limited to this, and other panel members are provided on the back surface of the display liquid crystal panel 110. May be pasted.

  In the above embodiment, the active matrix drive type TN type display liquid crystal panel 110 is used. However, the present invention is not limited to this, and any display method can be used as long as it has a function of generating a display screen. The STN method may be used, or the drive method may be a passive matrix drive.

  The test evaluation actually performed will be described below.

(Test evaluation sample)
<LCD panel for display>
Four general active matrix transflective display liquid crystal panels with a polarizing plate attached to the center of each side of the panel were prepared. The reason why the transflective display type is used is that it is sensitive to changes in the thickness of the liquid crystal cell and display unevenness is likely to occur.

<Switching LCD panel>
Four switching liquid crystal panels manufactured as follows were prepared.

  First, a solution of a negative resist for spacer (trade name: JNPC-77 manufactured by Nippon Synthetic Rubber Co., Ltd.) was applied on a glass substrate coated with ITO by rotating it at 2000 rpm for 1 minute with a spin coater.

  Next, the glass substrate was calcined at 120 ° C. for 10 minutes in a clean oven to remove the residual solvent in the spacer.

  Next, it exposed using the photomask so that the desired translucent resin pattern used as an isotropic area | region may be formed. At this time, ultraviolet rays were exposed under the condition of an exposure amount of 200 mJ, and development was performed with a 2% aqueous solution of NaOH at 30 ° C. for 1 minute.

  Next, an alignment film made of polyamic acid was formed and baked at 250 ° C. for 30 minutes in a clean oven.

  Next, an alignment treatment was performed so as to obtain a desired alignment direction by rubbing the baked alignment film, thereby preparing a lower substrate.

  The upper substrate 1 was produced in the same manner as the lower substrate.

  Next, a peripheral sealing material (trade name: XN-21S manufactured by Mitsui Chemicals, Inc.) was formed on the upper substrate using a screen plate in which a frame-like seal shape was patterned.

  Next, heating was performed at 100 ° C. for 30 minutes in a clean oven to remove the residual solvent in the sealing material.

  Next, after bonding the upper and lower substrates, baking was performed at 200 ° C. for 60 minutes.

  Next, a liquid crystal material was injected into the gap between the bonded upper and lower substrates to form a liquid crystal layer serving as a parallax barrier, and polarizing plates were bonded to both sides to manufacture a switching liquid crystal panel. A parallel (homogeneous) liquid crystal layer was formed using a liquid crystal material having positive dielectric anisotropy. This liquid crystal layer has a retardation of λ / 2 when no voltage is applied. Further, the transmission axis directions of the polarizing plates were set to be substantially parallel to each other. Further, the alignment direction of the liquid crystal layer was set to 45 ° with respect to the transmission axis direction of the polarizing plate.

<Bonding of both panels>
The initiator content is 0.5%, 2.0%, 2.5%, 3.0%, 5.0%, 7.5%, 9.0% 12.0% and 15.0, respectively. The display liquid crystal panel and the switching liquid crystal panel were bonded to each other using 9 kinds of acrylic ultraviolet curable resin adhesive. At this time, the polarizing plate on the back side of the display liquid crystal panel was embedded in the ultraviolet curable resin adhesive. An acrylic resin containing a urethane acrylate oligomer and an acrylate ester was used as the acrylic ultraviolet curable resin adhesive.

  Next, an adhesive layer was formed by irradiating an ultraviolet ray with a light quantity of 1000 mJ by an ultraviolet irradiator (metal halide lamp) to cure the ultraviolet curable resin adhesive, thereby producing a display panel module in which both panels were bonded. Samples 1 to 9 were prepared in order from the lowest content of the reaction initiator. The light absorptance of light having a wavelength of 365 nm is 0.2%, 0.5%, 0.6%, 0.8%, 1.0%, 2.0%, 3% in the order of samples 1 to 9. 0.0%, 5.0% and 6.0%.

(Test evaluation method)
A driver, a backlight or the like was attached to each of the nine display panel modules of Samples 1 to 9 to display images, and the display unevenness level was visually evaluated.

  In addition, after holding each of the nine display panel modules of Samples 1 to 9 in a dry atmosphere at a temperature of 70 ° C. for 100 hours, 250 hours, and 500 hours, a driver, a backlight, and the like are attached to display an image, and display unevenness level Was visually evaluated.

  Furthermore, after holding each of the nine display panel modules of Samples 1 to 9 in an atmosphere of a temperature of 45 ° C. and a humidity of 95% for 100 hours, 250 hours and 500 hours, a driver, a backlight, etc. are attached to display an image. The display unevenness level was visually evaluated.

  Here, the display unevenness level was evaluated in five stages, with the state having no display unevenness being 0 level and the state having the most significant display unevenness being 4 levels. From the viewpoint of practicality, the 0 level and the 1 level are acceptable levels.

(Test evaluation results)
Tables 1 and 2 show the results of the test evaluation.

  According to Tables 1 and 2, in samples 1 to 8 whose light absorptivity is 5.0% or less without giving a history under an atmosphere of high temperature or high humidity, an image in which display unevenness is suppressed It can be seen that the display is made. As a result, although the adhesive quickly cures in the central portion of the adhesive layer, the cured surface layer inhibits the progress of ultraviolet rays in the outer peripheral portion, so that curing does not proceed smoothly in the thickness direction, and the adhesive thickness This is considered to be because the central portion having a small thickness and the outer peripheral portion having a large adhesive thickness are formed in different cured states.

  When giving a history under an atmosphere of high temperature or high humidity, in samples 1 to 4 having a light absorption rate lower than 1.0%, the holding time in an atmosphere of high temperature or high humidity is long. It can be seen that display unevenness tends to occur as the light absorptance decreases. In other words, Samples 5 to 8 having a light absorptance of 1.0 to 5.0% are less affected by the history under a high temperature or high humidity atmosphere. It can also be seen that if the light absorptance is higher than 5.0%, the adhesion performance is hindered.

  From the above results, it is better to form the adhesive layer with a photo-curing resin having a light absorption rate of 5.0% or less after curing, which is also affected by holding in a high temperature or high humidity atmosphere. From the viewpoint of suppressing, it is preferable to form the adhesive layer with a photocurable resin having a light absorption rate after curing of 1.0 to 5.0%.
