Description

  The present invention relates to a liquid crystal display device and an electronic apparatus.

  Conventionally, a normally white mode TN (Twisted Nematic) mode is known as the most widely used method in liquid crystal display devices. Recently, TN mode liquid crystal display devices are making remarkable progress, and their image quality is improved to the same level as CRT. However, the TN mode liquid crystal display device has a great disadvantage that the viewing angle is narrow. The solution to this drawback is a VA (Vertical Alignment) mode in which a liquid crystal having negative dielectric anisotropy is vertically aligned between a pair of opposing substrates, and is currently commercialized in liquid crystal televisions and the like. . Such a VA mode liquid crystal display device has a wide viewing angle and high contrast.

  In a VA mode liquid crystal display device, it is known that wide viewing angle characteristics can be realized by adopting a configuration in which the alignment direction of liquid crystal molecules is divided into a plurality of different directions in a pixel. Here, specific configurations for performing the alignment division include a configuration in which a slit is provided in a transparent electrode such as ITO, and a configuration in which a protrusion is provided above the transparent electrode. A technique for controlling the direction in which the vertically aligned liquid crystal tilts when a voltage is applied by providing a portion is disclosed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 11-242225

By the way, when paying attention to the liquid crystal material on the protrusions used for the alignment division, the liquid crystal molecules on the protrusions are not completely perpendicular to the substrate, and have a certain degree of inclination with the inclination of the protrusions. There is a problem that birefringence occurs due to the tilt of the liquid crystal molecules, light leaks, and the contrast is lowered.
In addition, a fringe effect that causes the equipotential lines at the slit interface to become dense also occurs at the slit interface provided in the transparent electrode. Especially when the driving OFF potential is 0 V or more, the liquid crystal molecules are slightly caused by a weak electric field. There is a problem of tilting and causing a decrease in contrast.

  The present invention was devised in view of the above-described problems, and is caused by protrusions and slits used for alignment division in a liquid crystal display device having a liquid crystal with negative dielectric anisotropy whose initial alignment state is vertical alignment. An object of the present invention is to provide a liquid crystal display device and an electronic apparatus that can prevent a decrease in contrast.

In order to achieve the above object, the present invention employs the following configuration.
The liquid crystal display device of the present invention is a liquid crystal display device comprising a liquid crystal layer made of a liquid crystal having a negative dielectric anisotropy in which the initial alignment state is vertical alignment between a pair of substrates arranged opposite to each other. In addition, at least one of the pair of substrates is provided with an alignment regulating means for regulating the alignment of the liquid crystal, and at least one of the pair of substrates corresponds to the alignment regulating means. A light shielding film is formed at a position.
Here, the specific structure of the orientation regulating means is preferably composed of a slit portion, a protrusion portion, or both.

Since the liquid crystal display device of the present invention has the alignment regulating means, it is a preferable configuration for controlling the alignment direction at the time of electric field application particularly in the liquid crystal in the vertical alignment mode. When the vertical alignment mode is used, a negative type liquid crystal is generally used. However, since the liquid crystal molecules in the initial alignment state are standing perpendicular to the substrate surface by applying an electric field, no contrivance is required. If this is not done, the direction in which the liquid crystal molecules fall cannot be controlled, resulting in disorder of alignment and degrading display characteristics. Therefore, in adopting the vertical alignment mode, the control of the alignment direction of the liquid crystal molecules when an electric field is applied is an important factor.
Therefore, in the liquid crystal display device of the present invention, since the alignment regulating means is formed on the sandwiching surface of the liquid crystal layer, it is possible to regulate or control the direction in which the liquid crystal molecules are tilted, and the alignment is hardly disturbed, and an afterimage or a spot-like shape is caused. Display defects such as non-uniformity can be suppressed, and a wider viewing angle can be realized.

Furthermore, the liquid crystal display device of the present invention is not simply provided with the alignment regulating means, but has a configuration in which a light-shielding film is formed at a position corresponding to the alignment regulating means. Even when birefringence occurs due to the inclination of the liquid crystal molecules, the light shielding film suppresses light leakage and prevents a decrease in contrast. Therefore, high contrast display is possible.
In particular, it is preferable to form a light-shielding film at a position corresponding to the protruding portion among the orientation regulating means. In the vicinity of the protruding portion, the inclination of the liquid crystal molecules is larger than that in the vicinity of the slit portion, and birefringence acts greatly, so that light leakage also increases. Therefore, even if the light shielding film is only formed at the position corresponding to the protrusion, light leakage can be efficiently suppressed.

Further, the liquid crystal display device is characterized in that the light shielding film is formed only on one of the pair of substrates.
In this way, the same effect as the liquid crystal display device can be obtained, and a low-cost liquid crystal display device can be provided as compared with the configuration in which the light shielding film is provided on each of the pair of substrates.

Further, in the liquid crystal display device, the light shielding film corresponding to the orientation control means provided on at least one of the pair of substrates is formed on the same substrate.
In this way, the same effect as the liquid crystal display device can be obtained, and the positions of the light shielding film and the alignment regulating means can be made to correspond with high accuracy.
In the case where the light shielding film and the alignment regulating means are formed on the same substrate, they are formed with high accuracy by a photolithography technique or the like so that the positions of the two correspond. On the other hand, in the case where the light shielding film and the orientation regulating means are respectively formed on the pair of substrates, it is necessary to bond the pair of substrates to each other via the sealing material after the sealing material is formed on the one substrate. . Here, the positions of the light shielding film and the alignment regulating means need to be aligned with high accuracy, and alignment is difficult.
Therefore, by forming the light shielding film and the orientation regulating means on the same substrate, errors in bonding the substrates can be ignored and the positions of the light shielding film and the orientation regulating means can be made to correspond with high accuracy.

In the liquid crystal display device, the light-shielding film formed on the substrate on the light incident side of the liquid crystal layer of the pair of substrates is made of a metal having light reflectivity.
In this way, the light shielding film has not only the function of blocking the leaked light in the vicinity of the orientation regulating means but also the function of reflecting the light, so that the light incident on the light shielding film is reflected as it is and returns to the backlight. And reused as outgoing light. That is, the light utilization efficiency can be improved, and the luminance can be improved.

In addition, an electronic apparatus according to the present invention includes the liquid crystal display device described above.
Here, as an electronic device, information processing apparatuses, such as a mobile telephone, a mobile information terminal, a clock, a word processor, a personal computer, etc. can be illustrated, for example.
Therefore, according to the present invention, since the display unit using the liquid crystal display device described above is provided, it is possible to provide an electronic apparatus including a display unit with a wide viewing angle and excellent display characteristics. Become.

This is a transmissive liquid crystal display device.
FIG. 1 shows an equivalent circuit for the liquid crystal display device 100 of the present embodiment. The liquid crystal display device 100 includes a scanning signal driving circuit 110 and a data signal driving circuit 120.

On the contrary, the TFD element 40 is connected to the data line 9 side and the liquid crystal display element 160 is connected to the data line 9 side. The display element 160 may be provided on the scanning line 13 side.

  Next, the planar structure (pixel structure) of the electrodes provided in the liquid crystal display device 100 of the present embodiment will be described with reference to FIG. As shown in FIG. 2, in the liquid crystal display device 100 of the present embodiment, pixel electrodes 31 having a rectangular shape in plan view connected to the scanning lines 13 via the TFD elements 40 are provided in a matrix, and the pixel electrodes The common electrode 9 is provided in a strip shape (stripe shape) so as to face the surface 31 in the direction perpendicular to the paper surface. The common electrode 9 is formed of data lines and has a stripe shape that intersects the scanning lines 13. In the present embodiment, each region in which each pixel electrode 31 is formed is one dot region, and each dot region arranged in a matrix is provided with a TFD element 40, and display is possible for each dot region. It has a structure.

Here, the TFD element 40 is a switching element that connects the scanning line 13 and the pixel electrode 31, and the TFD element 40 is formed on the surface of the first conductive film having Ta as a main component and the first conductive film. , An MIM structure including an insulating film containing Ta ₂ O ₃ as a main component and a second conductive film formed on the surface of the insulating film and containing Cr as a main component. The first conductive film of the TFD element 40 is connected to the scanning line 13 and the second conductive film is connected to the pixel electrode 31.

Next, a configuration of main parts of the liquid crystal display device 100 of the present embodiment will be described based on FIG.
3A is a schematic diagram illustrating a pixel configuration of the liquid crystal display device 100, particularly a planar configuration of the pixel electrode 31, and FIG. 3B is a schematic diagram illustrating an AA ′ cross section of FIG. is there.
FIG. 3B is a diagram showing a cross section of the red colored layer 22R as a representative of the colored layer 22, and the cross-sectional structures of the other colored layers 22B and 22G are the same except that the color of the colored layer is different. It has a configuration.

As shown in FIG. 2, the liquid crystal display device 100 according to the present embodiment has a dot region provided with a pixel electrode 31 inside a region surrounded by the data lines 9, the scanning lines 13, and the like. In this dot area, as shown in FIG. 3A, one colored layer of the three primary colors is arranged corresponding to one dot area, and three dot areas (D1, D2, D3) are arranged. Pixels including the colored layers 22B (blue), 22G (green), and 22R (red) are formed. Each dot area (D1, D2, D3) is provided with a protrusion 28 and a slit 29 corresponding to the orientation regulating means of the present invention. The protrusion 28 and the slit 29 have a symmetrical pattern with the center line CL as an axis, and are disposed adjacent to each other. Here, the angle formed by the direction in which the protruding portion 28 and the slit portion 29 extend and the center line CL is 45 °. By doing so, it is possible to control the direction in which the liquid crystal molecules are tilted when a voltage is applied to the liquid crystal layer 50 to 45 ° from the transmission axis of the polarizing plate.
FIG. 3A shows three adjacent dot areas. The TFD element 40 is provided in each dot area, and a voltage is applied to the liquid crystal display element 160 for each dot area. Can be applied.

On the other hand, as shown in FIG. 3B, the liquid crystal display device 100 of the present embodiment is a liquid crystal in which the initial alignment state is vertically aligned between the upper substrate 25 and the lower substrate 10 disposed opposite thereto, A liquid crystal layer 50 made of a liquid crystal material having a negative dielectric anisotropy is sandwiched.
The lower substrate 10 has a configuration in which various layer films are laminated with a substrate body 10A made of a translucent material such as quartz or glass as a main component.
A color filter 22 (a red colored layer 22 </ b> R in FIG. 3B) is provided on the surface of the substrate body 10 </ b> A that faces the upper substrate 25.
Further, on the same surface of the substrate body 10A, a black matrix (light-shielding film) BM having a predetermined plane pattern is formed adjacent to the color filter 22. As shown in FIG. 3A, the black matrix BM is provided so as to surround the periphery of the colored layer 22R, and the black matrix BM forms boundaries between the dot regions D1, D2, and D3.
A matrix pixel electrode 31 made of a transparent conductive film such as indium tin oxide (hereinafter abbreviated as ITO) is provided above the color filter 22 and the black matrix BM. The pixel electrode 31 is provided with a slit portion 29 as an alignment regulating means. As shown in FIG. 2, the pixel electrode 31 is connected to the scanning line 13 via the TFD element 40 and applies a voltage to the liquid crystal layer 50 in accordance with the voltage supplied to the scanning line 13. It has become. In addition, an alignment film (not shown) is provided so as to cover the uppermost surface of the pixel electrode 31 and the stepped portion where the slit portion 29 is provided.

  Here, the alignment film is made of a material such as polyimide and functions as a vertical alignment film for aligning liquid crystal molecules perpendicularly to the film surface, and is not subjected to alignment treatment such as rubbing. Thus, in a liquid crystal display device using vertically aligned liquid crystals (liquid crystal molecules having negative dielectric anisotropy) that are divided and aligned without rubbing, electrode openings, dielectrics on the electrodes, and the like are partially provided in the pixels. Thus, it is necessary to control the direction in which the liquid crystal molecules fall by suitably distorting the electric field in the pixel. If this liquid crystal alignment control is insufficient, the liquid crystal molecules are tilted in a random direction while maintaining a domain having a certain size in the plane. In such a state, a region having different viewing angle characteristics is generated in a part of the surface of the display region, and as a result, a rough unevenness can be seen. Therefore, in order to regulate the orientation of the liquid crystal molecules of the liquid crystal layer 50, that is, to regulate the tilt direction when a voltage is applied between the electrodes with respect to the liquid crystal molecules that are vertically aligned in the initial state, A protrusion 28 described later is provided.

  Next, the upper substrate 25 has a configuration in which various layer films are formed by mainly using a substrate body 25A made of a light-transmitting material such as quartz or glass. On the surface of the substrate body 25A facing the lower substrate 10, a common electrode 9 made of a transparent conductive film such as ITO, a projection 28 functioning as an orientation regulating means, and the lower substrate 10 made of polyimide or the like And a vertical alignment film (not shown). In FIG. 3A, the common electrode 9 is formed in a stripe shape extending in the vertical direction on the paper surface. In each dot region formed side by side with the dot regions (D1, D2, D3) on the paper surface. It is configured as a common electrode. The protrusion 28 is formed of a resin material made of an organic film such as acrylic resin, and is formed so as to protrude from the surface of the upper substrate 25 to the liquid crystal layer 50 in the vertical direction of the substrate surface.

  Next, a polarizing plate 19 is formed on the outer surface side of the lower substrate 10 (a side different from the surface sandwiching the liquid crystal layer 50), and a polarizing plate 17 is formed on the outer surface side of the upper substrate 25. , 19 are configured to transmit only linearly polarized light having a polarization axis in a predetermined direction, and are installed in crossed Nicols. A backlight 15 serving as a light source for transmissive display is provided outside the polarizing plate 19 formed on the lower substrate 10.

Next, features of the liquid crystal display device 100 of the present invention will be described.
As shown in FIG. 3B, the black matrix BM is provided corresponding to the position of the projection 28 protruding from the upper substrate 25 toward the liquid crystal layer 50 (reference numeral X in the figure), and the pixel electrode It is provided at a position corresponding to the slit portion 29 provided in 31. That is, when viewed in plan as shown in FIG. 3A, the positions of the protrusions 28 and the slits 29 coincide with the positions of the black matrix BM and overlap. Further, the black matrix BM is made of a metal material having high light reflectivity such as aluminum or silver, and not only has a function of shielding light but also reflects light incident from the backlight 15 to the lower substrate 10 side. Are emitted. Further, the width of the black matrix BM is preferably larger than or the same as the widths of the protrusions 28 and the slits 29.

As described above, since the liquid crystal display device 100 has the protrusions 28 and the slits 29 as the alignment regulating means, a preferable configuration for controlling the alignment direction at the time of applying an electric field particularly in the liquid crystal in the vertical alignment mode. It becomes. When the vertical alignment mode is used, a negative type liquid crystal is generally used. However, since the liquid crystal molecules in the initial alignment state are standing perpendicular to the substrate surface by applying an electric field, no contrivance is required. If this is not done, the direction in which the liquid crystal molecules fall cannot be controlled, resulting in disorder of alignment and degrading display characteristics. Therefore, in adopting the vertical alignment mode, the control of the alignment direction of the liquid crystal molecules when an electric field is applied is an important factor.
Therefore, in the liquid crystal display device 100, since the protrusions 28 and the slits 29 are formed on the sandwiching surface of the liquid crystal layer, it is possible to regulate or control the direction in which the liquid crystal molecules are tilted, and it is difficult for alignment disorder to occur. Display defects such as spotted unevenness can be suppressed, and a wider viewing angle can be realized.

Further, the liquid crystal display device 100 described above has a configuration in which the black matrix BM is formed at positions corresponding to the projections 28 and the slits 29 instead of simply providing the projections 28 and the slits 29. Therefore, even if birefringence occurs due to the tilt of the liquid crystal molecules in the vicinity of the protrusions 28, the black matrix BM suppresses light leakage and prevents a decrease in contrast. In addition, since the fringe effect is generated in the vicinity of the slit portion 29, even if the liquid crystal molecules are slightly tilted, the light shielding film suppresses light leakage and prevents a decrease in contrast. Therefore, high contrast display is possible.
Moreover, since the leakage of light can be further suppressed by making the width of the black matrix BM larger than the widths of the protrusions 28 and the slits 29, the effect of increasing the contrast can be further promoted.

  In the above-described liquid crystal display device 100, since the black matrix BM is formed of a metal having light reflectivity, the black matrix BM has not only a function of blocking light but also a function of reflecting light. It becomes. Therefore, the light incident on the black matrix BM from the backlight 15 side is reflected as it is, returns to the backlight 15, and is reused as emitted light. Therefore, there is almost no decrease in brightness due to the provision of the light shielding film. That is, the reflected light from the black matrix BM is emitted to the upper substrate 25 side, so that the light use efficiency can be improved and the luminance can be improved.

In the present embodiment, a configuration in which the black matrix BM is provided corresponding to each of the protrusions 28 and the slits 29 is employed. However, a configuration in which the black matrix BM is provided corresponding to only the protrusions 28 is employed. May be.
This is because, among the orientation regulating means, in particular, the vicinity of the protrusion 29 has a characteristic that the inclination of the liquid crystal molecules is larger than that of the vicinity of the slit 29 and the birefringence acts greatly, so that light leakage also increases. is there. Therefore, the effect described above can be obtained as desired even by forming the black matrix BM at a position corresponding only to the protrusion 28.

  In the present embodiment, the configuration in which the color filter 22 is provided on the lower substrate 10 side is employed, but this is not a limitation. If the black matrix BM is provided corresponding to the protrusions 28 and the slits 29, a configuration in which a color filter is formed on the upper substrate 25 side may be employed.

(Second Embodiment)
Next, a second embodiment according to the present invention will be described with reference to the drawings. In addition, in each figure, in order to make each layer and each member into a size that can be recognized on the drawing, the scale is varied for each layer and each member. Further, the same components as those in the first embodiment are denoted by the same reference numerals, and the description is simplified.

  Differences between the present embodiment and the first embodiment will be described. In the first embodiment, the black matrix BM is provided on the lower substrate 10. On the other hand, in this embodiment, the black matrix is also provided on the upper substrate 25. In the present embodiment, the resin film 26 is provided on the upper substrate 25.

  Next, the pixel configuration of the liquid crystal display device 100 ′ according to the present embodiment will be described with reference to FIG. 4. 4A is a schematic diagram illustrating a planar configuration of the pixel electrode 31, and FIG. 4B is a schematic diagram illustrating a main part of the cross-sectional structure in FIG. 4A.

FIG. 4A is the same as FIG.
As shown in FIG. 4B, the lower substrate 10 is provided with a color filter 22, a black matrix BM, a pixel electrode 31, a slit portion 29, and a polarizing plate 19, and the first embodiment. As a configuration different from the configuration, the black matrix BM is formed corresponding to only the slit portion 29.
The upper substrate 25 is provided with the common electrode 9, the projecting portion 28, and the polarizing plate 17. Further, as a different configuration from the first embodiment, the black matrix BM ′ corresponds to only the projecting portion 28, and the substrate body 25A. A resin film 26 is formed so as to cover the black matrix BM ′. The resin film 26 is made of an organic film such as an acrylic resin, and is provided between the common electrode 9 and the substrate body 25A.
Here, the black matrix BM ′ and the protrusions 28 are provided in a state of being positioned with high accuracy, and are formed by a known patterning method such as a photolithography technique.
The black matrix BM ′ is made of a resin material or the like and is formed of a material that does not have light reflectivity. With such a configuration, reflection of external light incident from the substrate 25 side can be prevented, and thus display with higher display quality is possible.

As described above, in the liquid crystal display device 100 ′, the protrusions 28 and the slits 29 are formed on the sandwiching surface of the liquid crystal layer, as in the first embodiment, so that the liquid crystal molecules exhibit vertical alignment in the initial state. In addition, it is possible to regulate or control the direction in which the liquid crystal molecules are tilted, the alignment is less likely to be disturbed, display defects such as afterimages and spotted unevenness can be suppressed, and a wider viewing angle can be realized. Further, since the black matrixes BM and BM ′ are provided at positions corresponding to the protrusions 28 and the slits 29, light leakage due to the inclination of the liquid crystal molecules and the fringe effect can be suppressed, and high contrast display can be achieved. .
In the present embodiment, since the black matrix BM ′ and the protrusions 28 are formed on the same substrate (upper substrate 25), the step of bonding the upper substrate 25 and the lower substrate 10 through a sealing material is performed. The effect that it is not necessary to carry out with high precision is acquired.

More specifically, the black matrix BM ′ and the protrusions 28 are formed on the upper substrate 25 with high accuracy by the photolithography technique or the like so that the positions of both correspond. On the other hand, when the black matrix BM and the protrusions 28 are formed on the pair of upper and lower substrates 10 and 25, respectively, the pair of substrates 10 and 25 must be bonded to each other after the sealing material is formed on one substrate. There is. Here, it is necessary to align the positions of the black matrix BM and the protrusions 28 with high accuracy, and the alignment is difficult.
Therefore, by forming the black matrix BM and the protrusions 28 on the same substrate as in the present embodiment, an error in bonding of the upper and lower substrates 10 and 25 can be ignored, and the positions of the black matrix BM ′ and the protrusions 28 can be ignored. Can be handled with high accuracy.

For example, in the above-described embodiment, an example in which the present invention is applied to an active matrix liquid crystal display device using TFD as a switching element has been described.
