Description

  The present disclosure relates to a display device having a lens member on the viewing surface side of a display panel, a method of manufacturing the same, and an electronic device provided with such a display device.

  In the trend of electronic devices in recent years, miniaturization is further advanced. On the other hand, since the demand for larger displays (display devices) is strong, in order to meet the trend of miniaturization of electronic devices, it is necessary to narrow the frame of the display devices (display panel) itself. . However, with regard to the frame width in the display panel, those smaller than 1 mm have already been developed, and it is considered that the physical narrowing of the frame is near the limit.

Embodiment
[Configuration of Liquid Crystal Display Device 1]
FIG. 1 is a perspective view schematically illustrating an appearance configuration of a display device (liquid crystal display device 1) according to an embodiment of the present disclosure. Further, FIG. 2 shows an example of a cross-sectional configuration (an example of a cross-sectional configuration taken along line II-II in FIG. 1) in the liquid crystal display device 1.

  As shown in FIG. 1, the liquid crystal display device 1 includes the backlight 10, the liquid crystal display panel 11, and the lens member 12 in this order from the back surface (back surface) side to the viewing surface (display surface, front surface) side. There is. The liquid crystal display device 1 also includes a resin layer 13 between the liquid crystal display panel 11 and the lens member 12 as shown in FIG.

  The backlight 10 is disposed on the back side of the liquid crystal display panel 11 and is a light source unit that emits light toward the liquid crystal display panel 11. The backlight 10 includes, for example, light sources such as CCFLs (Cold Cathode Fluorescent Lamps) and LEDs (Light Emitting Diodes), and various optical sheets (see FIG. Both are not shown).

(Liquid crystal display panel 11)
The liquid crystal display panel 11 is a display panel configured using a liquid crystal element, and as shown in FIG. 1, an effective display area 11a including a plurality of pixels (not shown) and an outer edge of the effective display area 11a. And a frame area (non-display area) 11b located at the (periphery). The liquid crystal display panel 11 also includes a polarizing plate 111A (incident side polarizing plate), a substrate 110A, a liquid crystal layer 112a, and light shielding from the back surface side (backlight 10 side) to the observation surface side (lens member 12 side). It has a laminated structure having a film 112b, a substrate 110B, and a polarizing plate 111B (emission side polarizing plate) (see FIG. 2).

  Each of the substrates 110A and 110B (a pair of substrates) is a substrate having light transparency, and is configured using, for example, a glass substrate or the like. The substrate 110A functions as a TFT substrate on which elements such as thin film transistors (TFTs) and wirings (neither of which are shown) are formed. On the other hand, the substrate 110B functions as a CF substrate on which a color filter (CF: Color Filter) and a black matrix (BM) are formed.

  The polarizing plates 111A and 111B are optical elements each having a function of selectively transmitting a specific polarization component of incident light and absorbing the other polarization component. These polarizing plates 111A and 111B are arranged such that their transmission axes are orthogonal to each other (cross Nicol arrangement), or are arranged such that their transmission axes are parallel to each other (parallel Nicol arrangement) .

  The liquid crystal layer 112a is interposed between the substrates 110A and 110B, and constitutes a liquid crystal element in the effective display area 11a. The light shielding film 112 b is disposed in the frame area 11 b. In the frame area 11b, for example, various peripheral circuits (such as drive circuits) are formed.

  The resin layer 13 functions as an adhesive layer for bonding the liquid crystal display panel 11 and the lens member 12 to each other, and is made of, for example, a resin material such as acrylic. An air layer (gap layer) may be provided between the liquid crystal display panel 11 and the lens member 12 instead of the resin layer 13 as described above, and so forth.

(Lens member 12)
The lens member 12 is disposed on the viewing surface side of the liquid crystal display panel 11, and has a lens function part 12a in at least a part of the peripheral area (outer end area). Specifically, in the present embodiment, the lens functional portion 12a functioning as a convex lens is formed on one of the four end sides of the lens member 12 (see FIG. 1). The lens member 12 is made of, for example, an optical glass material such as BK7 or a resin material such as acryl or polycarbonate.

  Further, in the present embodiment, the outline of the lens member 12 on the side of the lens function part 12a is disposed outside the outline of the frame area 11b of the liquid crystal display panel 11 (see FIG. 2). In other words, the outer end of the lens member 12 on the side of the lens function unit 12a is positioned outside the outer end (outer shape) of the entire liquid crystal display panel 11 (both the effective display area 11a and the frame area 11b) A lens member 12 is disposed.

[Method of Manufacturing Liquid Crystal Display Device 1]
The liquid crystal display device 1 can be manufactured, for example, as follows. That is, first, the liquid crystal display panel 11 having the effective display area 11a and the frame area 11b described above is formed. Specifically, after a substrate 110A as a TFT substrate and a substrate 110B as a CF substrate are respectively formed using a glass substrate or the like, a liquid crystal is injected between the substrates 110A and 110B to form the liquid crystal layer 112a. Form. In addition, the light shielding film 112b is formed in the frame area 11b between the substrates 110A and 110B. Thus, the liquid crystal display panel 11 is formed.

  Next, the backlight 10 is disposed on the back side of the liquid crystal display panel 11, and the lens member 12 having the lens function part 12 a is formed on the viewing surface side of the liquid crystal display panel 11. Specifically, after forming such a lens member 12 using, for example, acrylic or the like, the lens member 12 and the liquid crystal display panel 11 are bonded to each other through the resin layer 13. At this time, as described above, the outline of the lens member 12 on the side of the lens function part 12 a is arranged outside the outline of the frame area 11 b of the liquid crystal display panel 11. Thus, the liquid crystal display device 1 shown in FIGS. 1 and 2 is completed.

[Operation and Effect of Liquid Crystal Display Device 1]
(basic action)
In this liquid crystal display device 1, as shown in FIGS. 1 and 2, the light (for example, illumination lights L10 and L20) emitted from the backlight 10 is subjected to liquid crystal display according to control by a drive circuit (not shown). It is modulated for each pixel in the panel 11. Thereby, the display light L1 (for example, display light L11, L12) is emitted from the viewing surface side of the liquid crystal display panel 11 and is incident on the lens member 12. The display light L2 (L11, L12) is emitted from the lens member 12 to the outside as display light L2 (for example, display light L12, L22). Thus, the liquid crystal display device 1 displays an image.

  At this time, as shown in FIG. 2, the display lights L11 and L21 emitted from the frame area 11b side of the effective display area 11a are subjected to optical path conversion by the lens function unit 12a of the lens member 12, and then display light The light is emitted to the outside as L12 and L22. Specifically, the display light L11 and L21 obliquely incident on the lens member 12 in the outward direction of the lens member 12 is refracted by the lens function part 12a, so that the thickness direction of the liquid crystal display device 1 (vertical direction Optical path conversion, and emitted to the observer side. In this manner, since the display light appears to be emitted to the observer also in the frame area 11b, a pseudo narrowing action is performed.

(Comparative example)
Here, FIG. 3 schematically shows a cross-sectional configuration of a display device (liquid crystal display device 101) according to a comparative example. Similar to the liquid crystal display device 1 of the present embodiment, the liquid crystal display device 101 of this comparative example includes the backlight 10, the liquid crystal display panel 11, the resin layer 13 and the lens member 12 from the back side to the viewing side. It is equipped in this order.

  However, in the liquid crystal display device 101, unlike the liquid crystal display device 1, the lens member 12 is disposed such that the outline of the lens member 12 on the lens function unit 12a side is positioned on the frame area 11b of the liquid crystal display panel 11. It is done. In other words, although the outline of the lens member 12 on the side of the lens function unit 12a is disposed outside the outline of the effective display area 11a in the liquid crystal display panel 11, the outline is disposed inside the outline of the frame area 11b. It is done.

  Therefore, in the liquid crystal display device 101, a part of the display light (for example, the display light L21 shown in FIG. 3) obliquely incident on the lens member 12 in the outward direction of the lens member 12 is the lens member 12. It is refracted at the side surface side of the lens member 12 instead of the lens function part 12a. As a result, part of the display light (for example, display light L21) emitted from the frame area 12b side in the effective display area 12a is not converted in optical path in the thickness direction (vertical direction) of the liquid crystal display device 1, It will be emitted towards the outside of the device 101. That is, the display light whose optical path is converted in the lens member 12 (lens function unit 12a) is difficult to reach the observer depending on the area of the emission source in the effective display area 11a. As a result, for the observer, the area (a part 101b shown in FIG. 3 here) of a part (a part on the outer edge side) of the frame area 11b becomes an area that looks dark. That is, in the liquid crystal display device 101, the effect of pseudo narrowing of the frame using the lens member 12 (lens function unit 12a) is insufficient.

(Operation of the present embodiment)
On the other hand, in the liquid crystal display device 1 of the present embodiment, as shown in FIG. 2, the outline of the lens member 12 on the side of the lens function portion 12 a is more than the outline of the frame area 11 b of the liquid crystal display panel 11. It is located outside. In other words, the lens member 12 is positioned such that the outer end of the lens member 12 on the side of the lens function unit 12a is positioned outside the outer end of the entire liquid crystal display panel 11 (both the effective display area 11a and the frame area 11b). Is arranged.

  As a result, display light (in this case, display lights L11 and L21) emitted from the frame area 11b side in the effective display area 11a is easily subjected to optical path conversion by the lens function unit 12a to the observer side. That is, unlike the comparative example, the display light whose optical path is changed in the lens member 12 (lens function unit 12a) can easily reach the viewer as a whole regardless of the area of the emission source in the effective display area 11a. Become. Therefore, in the present embodiment, the artificial narrowing of the frame by the lens function unit 12a is intensified as compared with the comparative example in which part of the display light (for example, the display light L21) does not easily reach the viewer side. (An area that looks dark in the frame area 11b is less likely to exist).

  As described above, in the present embodiment, the outline of the lens member 12 on the side of the lens function unit 12a is arranged outside the outline of the frame area 11b of the display panel 11, so from the effective display area 11a The emitted display light can be made easy to reach the observer side as a whole. Therefore, it is possible to intensify the pseudo narrowing effect of the lens function unit 12a, and it is possible to achieve the narrowing of the frame as compared with the prior art.

  In addition, for example, even when a plurality of liquid crystal display panels 11 are arranged in parallel in the liquid crystal display device 1 or the like, joints (frame areas between the liquid crystal display panels 11) can be seen between adjacent liquid crystal display panels 11 In this case, it is also possible to achieve high image quality.

<Modification>
Subsequently, modified examples (modified examples 1 to 7) of the above embodiment will be described. The same components as those in the above embodiment are given the same reference numerals, and the description thereof will be appropriately omitted.

[Modification 1]

  That is, in this liquid crystal display device 1A, in the liquid crystal display device 1 of the above-described embodiment, the polarizing plate 111B on the emission side is a resin layer instead of the inside of the liquid crystal display panel 11 (between the substrate 110B and the resin layer 13). The lens 13 is disposed between the lens 13 and the lens member 12, and the other configuration is the same. Specifically, the polarizing plate 111B is attached (joined) on the back side (the liquid crystal display panel 11 side) of the lens member 12 here.

  With such a configuration, in the liquid crystal display device 1A of this modification, in addition to the effects of the above embodiment, the following effects can be obtained. That is, in the present modification, the polarizing plate 111B is attached to the back side of the lens member 12, whereby the outline of the polarizing plate 111B is positioned outside the outline of the liquid crystal display panel 11A. For this reason, in this modification, compared with the above-mentioned embodiment, the tolerance of a position gap at the time of arranging polarizing plate 111B can be enlarged, and narrowing-frame-ization is attained further by the bonding tolerance of this polarizing plate 111B. It becomes possible.

[Modification 2]
FIG. 5 is a perspective view schematically showing the appearance of the display (liquid crystal display 1B) according to the second modification. 6A and 6B respectively show an example of a cross-sectional configuration (an example of a cross-sectional configuration taken along line III-III in FIG. 5) in the liquid crystal display device 1B.

  In the liquid crystal display device 1B of this modification, as shown in FIG. 5, in the liquid crystal display device 1 of the above embodiment or the liquid crystal display device 1A of the modification 1, the periphery of the liquid crystal display panel 11 or the liquid crystal display panel 11A. The exterior member (housing, frame) 14 is further provided on at least a part of Such an exterior member 14 is made of, for example, a metal material such as aluminum or stainless steel.

In other words, the exterior member 14 is physically connected (connected) to the backlight 10. The lens member 12 is supported by the exterior member 14 in the outer end region of the lens function portion 12a. That is, the liquid crystal display device 1 </ b> B shown in FIG. 6A corresponds to the liquid crystal display device 1 further provided with the exterior member 14.

  Further, in the example of the liquid crystal display device 1B shown in FIG. 6B, the backlight 10, the liquid crystal display panel 11A, the resin layer 13, the polarizing plate 111B and the lens member 12 are directed from the back side to the viewing side. It is provided in this order. Then, as in the example of FIG. 6A, the lens member 12 is supported by the exterior member 14 in the outer end region of the lens functional unit 12a. That is, the liquid crystal display device 1B shown in FIG. 6 (B) corresponds to the liquid crystal display device 1A further provided with the exterior member 14.

  In this manner, in the liquid crystal display device 1B of the present modification, the lens member 12 is supported by the exterior member 14 in the outer end region of the lens function part 12a. In addition, it is possible to obtain the following effects. That is, when the lens member 12 is disposed over the frame area 11b, it is difficult to secure a space for supporting the lens member 12 from the viewpoint of physically narrowing the frame, and thus the mechanical strength in the liquid crystal display device decreases. There is a risk of Specifically, when the liquid crystal display panel 11 is bent or the like, the problem of strength reduction in practical use tends to occur. Therefore, by causing the exterior member 14 originally provided to also function as a support member for the lens member 12, the mechanical in the liquid crystal display device 1B can be provided without separately providing a dedicated support member (without increasing the member cost). Strength can be improved.
