Description

  The present invention relates to a liquid crystal display device.

The liquid crystal display device disclosed in Patent Document 1 is widely used as a display unit for electronic devices, for example. In general, a liquid crystal display device includes a liquid crystal panel and a backlight unit that irradiates the liquid crystal panel with light. The liquid crystal panel has a configuration in which a liquid crystal layer is sandwiched between a pair of opposed substrates, and sub-pixels are arranged on the pair of substrates. The sub-pixels are provided in a display area for displaying an image and a peripheral area (peripheral parting area) of the display area. The display unit of the electronic device is usually provided so that the display area and the peripheral parting area can be seen.

The sub-pixels provided in the display area are not provided with a light shielding portion, and display light can be emitted. On the other hand, the sub-pixel (dummy pixel) provided in the peripheral parting area is provided with a light-shielding portion in the entire sub-pixel so as not to transmit light. In the sub-pixels provided in the display area, part of the light incident on the display surface of the liquid crystal display device travels from the sub-pixels to the inside of the device, and is affected by the action of the optical sheet or the diffusion plate of the backlight unit. Injected outside.
On the other hand, in the peripheral parting area, the light incident on the display surface is absorbed by the light shielding portion. For this reason, for example, when the power supply of the liquid crystal display device is turned off, the appearance in which the peripheral portion of the display area is visually recognized darkly.

In recent years, highly-designed electronic devices have been demanded. For example, a proposal has been made to improve the design by showing the display portion as wide as possible. In particular, there is a demand for a liquid crystal display device that can be applied to a wide range of applications in which the display area and the peripheral parting area have the same appearance.
JP 11-295717 A

However, in a normal liquid crystal display device, the peripheral parting area looks dark, which hinders wide display of the display unit. For this reason, it cannot adapt to the use which can display a display part as widely as possible.
In view of the circumstances as described above, an object of the present invention is to provide a liquid crystal display device that can be adapted to applications in which a display unit can be shown as wide as possible.

In order to achieve the above object, a liquid crystal display device according to the present invention has a display area in which a pair of substrates are opposed to each other so as to sandwich a liquid crystal layer, has a display surface for displaying an image, and displays the image. And a liquid crystal panel in which a plurality of sub-pixels are arranged in a matrix in a plan view across a peripheral region provided around the display region, and provided on the surface opposite to the display surface of the liquid crystal panel, A transflective liquid crystal display device comprising a backlight unit for irradiating light to the liquid crystal panel, wherein a predetermined color is provided in each sub-pixel on the liquid crystal layer side of one of the pair of substrates. A color filter layer including a plurality of sub-pixels, and a sub-pixel in which an area in a plan view of the color layer in the sub-pixels provided in the peripheral region among the plurality of sub-pixels is provided in the display region In the color layer Characterized in that it is smaller than the area in view.

According to the present invention, a color filter layer composed of a predetermined color layer is provided in each subpixel on the liquid crystal layer side of one of the pair of substrates, and is provided in a peripheral region among the plurality of subpixels. Since the area of the color layer in the subpixel in plan view is smaller than the area of the color layer in the subpixel provided in the display area in plan view, the peripheral area is more than the display area. The amount of transmitted white light increases. For this reason, the brightness of the white light in the peripheral area can be made higher than the brightness of the white light in the display area. By increasing the brightness of white light, it is possible to suppress the peripheral area from appearing dark, and the appearance of the peripheral area can be brought close to the appearance of the display area. As a result, a liquid crystal display device that can be adapted to applications in which the display unit can be shown as wide as possible can be obtained.

In the liquid crystal display device, an opening is provided in a part of the color layer, and the opening of the color layer in the sub-pixel provided in the peripheral region among the plurality of sub-pixels is the display. It is characterized by being larger than the opening of the color layer in the sub-pixel provided in the region.
According to the present invention, an opening is provided in a part of the color layer, and an opening of the color layer in the sub-pixel provided in the peripheral area among the plurality of sub-pixels is provided in the display area. Since it is larger than the opening of the color layer in the pixel, the brightness of the white light in the peripheral area can be made higher than the brightness of the white light in the display area. By increasing the brightness of the white light, it is possible to suppress the peripheral area from appearing dark, and the external appearance of the peripheral area can be brought close to the external appearance of the display area. As a result, a liquid crystal display device that can be adapted to applications in which the display unit can be shown as wide as possible can be obtained.

In the liquid crystal display device, a light shielding portion that shields a partial region in the sub pixel is provided in a sub pixel arranged in the peripheral region among the plurality of sub pixels. .
Usually, since the light transmission region of the sub pixel provided in the peripheral region is shielded by the light shielding portion, the light does not pass through the sub pixel in the peripheral region. On the other hand, according to the present invention, a light shielding portion that shields a part of the area within the subpixel is provided in the subpixel arranged in the peripheral area among the plurality of subpixels. Light passes through an area of the sub-pixel where no light shielding portion is provided. Accordingly, part of the light incident on the display surface travels from this region into the apparatus, and is reflected by at least the backlight unit and emitted from the display surface. In this way, by allowing light to be emitted also from the sub-pixels in the peripheral area, the appearance of the peripheral area can be made closer to the appearance of the display area.

For example, it is made of a metal such as aluminum having a high light reflectance. In the display area 9, the area 10 a provided with the light reflection layer 42 is a reflective display area that reflects and displays light from the color filter substrate 5. Further, the region 10b where the light reflecting layer 42 is not provided is a transmissive display region in which light from the backlight unit 3 is transmitted and displayed.

The alignment film 46 is provided at the interface with the liquid crystal layer 6 so as to cover the resin layer 45 and the light reflection layer 42, and regulates the alignment of the liquid crystal molecules constituting the liquid crystal layer 6 with the alignment film 56.

The light shielding film 57 is made of a material such as chromium like the black matrix 51, and is provided so as to cover a region overlapping the region 10b of the peripheral parting region 8 where the light reflecting layer 42 is not provided in plan view. ing.

The color filter layer 50 is a color layer provided on the liquid crystal layer 6 side of the substrate 5a so as to overlap the subpixel 10 in plan view. The color filter layer 50 is composed of three color layers, for example, a red layer 50R, a green layer 50G, and a blue layer 50B made of a known material such as an organic material or an inorganic material. The red layer 50R is provided in a region overlapping the red sub-pixel in plan view. The green layer 50
G is provided in a region overlapping the green sub-pixel in plan view. The blue layer 50B is provided in a region overlapping the blue sub-pixel in plan view.

FIG. 4 is a diagram illustrating a planar configuration of one pixel in the peripheral parting region 8 for the color filter layer 50. Similar to the display area 9, pinholes 53R, 53G, and 53B for adjusting the luminance of each color are provided in part of the red layer 50R, the green layer 50G, and the blue layer 50B, respectively.
Pinholes 53R, 53G, and 53B provided in the red layer 50R, green layer 50G, and blue layer 50B in the peripheral parting area 8 are provided in the red layer 50R, green layer 50G, and blue layer 50B in the display area 9. Compared to the pinholes 53R, 53G, and 53B, the area in plan view is larger. Therefore, when each color layer provided in the sub pixel 10 in the display area 9 is compared with each color layer provided in the sub pixel 10 in the peripheral parting area 8, each color layer in the peripheral parting area 8 is more The area in plan view is small.

The gap layer 52 is made of a colorless and transparent material such as acrylic, for example, and is provided in a region that overlaps the light reflection region 10a of the sub-pixel 10 in plan view with the inter-pixel region 11 as a center. The common electrode 58 is an electrode formed of a transparent conductive material such as ITO, and is provided so as to cover the color filter layer 50 and the black matrix 51. Gap layer 52
Thus, a part of the common electrode 58 is formed so as to protrude toward the liquid crystal layer 6 as compared with the other part. Due to the presence of the gap layer 52, the gap of the reflection region can be reduced to about half of the gap of the transmission region. As a result, the optical path length of the reflected light and the optical path length of the transmitted light are equal. The alignment film 56 is provided at the interface with the liquid crystal layer 6 and regulates the alignment of liquid crystal molecules constituting the liquid crystal layer 6.

So as to be sandwiched between both substrates.

The backlight unit 3 has a known configuration. Specifically, a light source unit 3a such as an LED, a light guide plate 3b made of a transparent material such as acrylic resin, a diffusion plate 3c provided on the liquid crystal panel 2 side with respect to the light guide plate 3b, and a diffusion plate 3c The light collector 3d provided on the liquid crystal panel side 2 is mainly used. Light can be reflected on the surface of the diffusion plate 3c on the liquid crystal panel 2 side. Although not shown, a reflector is provided on the surface of the light guide plate 3b opposite to the liquid crystal panel 2. Light from the light source unit 3a is guided to the liquid crystal panel 2 side by the light guide plate 3b.

The action of external light in the liquid crystal display device 1 configured as described above will be described. As shown in FIG. 2, a part of the light component L <b> 1 of the external light enters the liquid crystal panel 2 from the transmissive display area 10 b of the display area 9. The light component L1 passes through the liquid crystal layer 6 and the TFT array substrate 4 and is reflected by the diffusion plate 3c of the backlight unit 3, and the TFT array substrate 4 and the liquid crystal layer 6 are reflected.
And is emitted from the transmissive display area 10 b of the color filter substrate 5 to the outside of the liquid crystal display device 1.

On the other hand, as shown in FIG. 2, in the peripheral parting region 8, the light component L2 different from the light component L1 out of the external light enters the liquid crystal panel 2 from the region 10b, for example. This light component L2
Passes through the liquid crystal layer 6 and is reflected by the light reflecting layer 42 of the TFT array substrate 4.
And is emitted from the region 10 b of the color filter substrate 5 to the outside of the liquid crystal display device 1.

Thus, according to the present embodiment, the area of each color layer 50R, 50G, 50B in the subpixel 10 provided in the peripheral parting region 8 in plan view is the subpixel 10 provided in the display region 9.
Since the area of each of the color layers 50R, 50G, and 50B is smaller than the area in plan view, the amount of white light transmitted through the peripheral parting area 8 is larger than that of the display area 9. For this reason, the brightness of the white light can be made higher than the brightness of the white light in the display area 9. By increasing the brightness of white light, it is possible to suppress the peripheral parting area 8 from appearing dark, and the appearance of the peripheral parting area 8 can be brought close to the appearance of the display area 9. Thereby, it is possible to obtain the liquid crystal display device 1 that can be adapted to applications in which the display unit can be shown as wide as possible.

The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, the sub pixel 10 in the peripheral parting region 8 is configured to cover the entire region 10b where the light reflecting layer 42 is not provided with the light shielding film 57. However, the present invention is not limited to this. . For example, as shown in FIG. 5, a configuration in which a part of the region 10b is covered with a light shielding film 57 may be employed. According to such a configuration, the light shielding film 57
In the region 57a where no is provided, light passes. Therefore, a part of the light incident on the liquid crystal display device 1 travels from the region 57a not covered with the light shielding film 57 into the device, and is reflected by at least the backlight unit 3 and emitted from the display surface. . In this way, by allowing light to be emitted also from the sub-pixels 10 in the peripheral parting area 8, the appearance of the peripheral parting area 8 can be made closer to the appearance of the display area 9.

In the above-described embodiment, the red layer 50R, the green layer 50G, and the blue layer 5 in the peripheral parting region 8 are used.
0B and the red layer 50R, the green layer 50G, and the blue layer 50B of the display area 9 are all pinholes 53.
However, the present invention is not limited to this. For example, each color layer of the display area 9 does not have a pinhole, that is, a color layer is provided on the entire surface of the sub-pixel 10. It may be a configuration. Thereby, since the brightness | luminance of white light becomes higher in the peripheral parting area | region 8, the external appearance of the peripheral parting area | region 8 can be made still closer to the external appearance of the display area 9. FIG.

Note that the shapes of the pinholes 53R, 53G, and 53B (the shapes of the color layers) are not limited to those described in the above embodiment. For example, as shown in FIG. 6, the red layer 214r
In the plan view, an elliptical pinhole 214ra is formed, and in the green layer 214g, an opening 214ga is formed so as not to be provided at the upper end portion and the lower end portion of the subpixel in the drawing, and the blue layer 214b is provided with a pin. A configuration in which no hole is provided may be used.

Further, as shown in FIG. 7, the red layer 314r is provided with an opening 314ra in a pattern having a circular planar shape, and the green layer 314g has an elliptical planar shape 314ga.
The blue layer 312b may not have a pinhole.

Further, as shown in FIG. 8, the color layer 414 in the sub-pixel may be provided with an opening having a polygonal planar shape. For example, the opening 414a is formed by using a mask pattern P4 having an octagonal planar shape formed by chamfering four corners of a rectangle. Here, the mask pattern P4 has eight corners, and the inner angles θ of these corners are all angles exceeding 90 degrees (that is, obtuse angles). In particular, in order to more effectively reduce variations in the opening shape and the opening area, it is preferable that all the internal angles θ are 110 degrees or more. Further, as shown in FIG. 9, a configuration in which regular hexagonal openings 514 a are formed in the colored layer 514 may be employed. Similar to the opening 414a, the opening 514a is formed by a mask pattern P5 having a regular hexagonal planar shape. This mask pattern P5 has all interior angles of about 120 degrees.

Also, as shown in FIG. 10, a strip-shaped opening 614ra is formed in the red layer 614r along the width direction of the red layer 614r, and an opening 614ga is provided in the green layer 614g so as not to be provided at the upper end of the sub-pixel. The green layer 614b may have a configuration in which a strip-shaped opening 614ba similar to the opening 614ra of the red layer 614r is formed on the lower end side. Any of the openings 614ra, 614ga, 614ba is configured to cross the short direction of the sub-pixel 600P. That is, the openings 614ra, 614ga, 614ba are configured to extend from a portion on one boundary line of the sub-pixel 600P and reach a portion on the other boundary line. In the illustrated example, rectangular sub-pixels 600P are formed, and each sub-pixel 600P has four edges. In addition, all cases where the opening is formed over two or more different edges of the sub-pixel 600P are included. Accordingly, not only when the sub-pixel 600P is traversed in the horizontal direction as shown in the figure, but also in the vertical direction of the sub-pixel 6P.
This includes the case of crossing 00P and the case of crossing the subpixel 600P diagonally. Further, when the opening crosses the pixel diagonally, a mode in which the opening is configured in a triangular shape near the corner of the sub-pixel 600P is included.

Further, the configuration shown in FIG. 11 may be used. Specifically, each color layer 714r, 7
14g and 714b are configured in the same way as in the case shown in FIG. 10 in that openings are configured so that adjacent pixels are not adjacent to each other across a boundary region. However, the transflective layer 712 in this example has the transmissive portion 7 at a different position between adjacent pixels.
10 is different from the configuration of FIG. 10 in that 12a is formed. More specifically, the transmissive portions 712a are arranged in a staggered manner (for example, alternately in the vertical direction in the drawing) according to the pixel arrangement along the transverse direction (the horizontal direction in the drawing) of the opening. Also in this example, in the pixel of the green layer 712g, the opening area of the opening 714ga is larger than the openings 714ra and 714ba provided in the other red layer 712r and blue layer 712b. The pattern is formed in such a manner that the opening 714ga is adjacent to the light transmission part 712a and the light transmission part 712a is adjacent to the openings 714ra and 714ba. This makes it possible to design the apertures between adjacent pixels to be more distant from each other.

Also, as shown in FIG. 12, the red layer R has a rectangular pinhole 112a in plan view.
The green layer G may have a structure in which a rectangular pinhole 112a is formed at the upper end and the lower end of the subpixel in the drawing, and the blue layer B is not provided with a pinhole. .

In 4ga and 814ba, a part of the reflective portion 812b of the transflective layer 812 is part of the colored layer 81.
4 is optically exposed so as not to be covered. A total of two openings 814ra, 814ga, and 814ba are provided in each pixel 800P, one at each of a pair of opposite sides. The planar shape of the cutout portions 815r, 815g, and 815b is a semicircular shape that does not have a corner portion obtained by cutting an ellipse along its major axis, and the opening portion 814a in the pixel 800P.
Has a shape in which a part of the opposing edges of the pixel 800P is formed in an arc shape. The cutout portions 815r, 815g, and 815b are located in the boundary region BR with the pixel 800P across the boundary line of the pixel 800P. The above configuration has openings 814ra and 814ga as mask patterns.
, 814ba are used as masks 820 to 822 having light shielding portions 820a to 822a (shown in FIGS. 13B to 13D). That is, the colored layers 814r, 814g, 8
The planar shape of the notches 815r, 815g, and 815b provided in 14b is a semicircular shape obtained by cutting an ellipse along the major axis. This is a planar shape like a semicircular shape in the patterning step. Can be formed by patterning with a mask pattern having a light shielding portion.

In other words, in the adjacent pixel 1010P, the opening is adjacent to the boundary region.

Further, the configuration shown in FIG. 16 may be used. Specifically, the red colored layer 111
4r, a green colored layer 1114g, and a blue colored layer 1114b, each having a notch portion 1115r that becomes an opening portion 1114ra in a pattern having a planar shape without a corner portion having a different size.
A notch 1115g to be the opening 1114ga and a notch 1015b to be the opening 1114ba are provided. Here, in the G (green) pixel, the opening area of the opening 1114ga that exposes a part of the reflecting portion 1112b is the largest, and in the R (red) pixel, the opening area of the opening 1114ga that exposes the reflecting portion 1112b is the next. In the B (blue) pixel, the opening area of the opening 1114ba that exposes the reflecting portion 1112b is configured to be the smallest.

Further, the configuration shown in FIG. 17 may be used. Specifically, colored layers 1214r, 1214g, and 1214b are formed on a plurality of R, G, and B pixels 1200P, respectively. An opening 1214ra is formed in the colored layer 1214r provided in the R (red) pixel, and an opening 1214ga is formed in the colored layer 1214g provided in the G (green) pixel, and B (blue). An opening 1214b is also formed in the colored layer 1214b provided in each pixel. All of the openings 1214ra, 1214ga, and 1214ba have an asymmetric octagonal planar shape in which all the corners have internal angles exceeding 90 degrees. In other words, the opening 121
Each of 4ra, 1214ga, and 1214ba has a polygonal planar shape that has five or more corners and does not have a circumscribed circle that touches all the corners.

Further, the configuration shown in FIG. 18 may be used. Specifically, colored layers 1314r, 1314g, and 1314b are formed on a plurality of R, G, and B pixels 1300P, respectively.
