[0040] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the disclosure is merely an example, and for those skilled in the art, appropriate changes that maintain the main purpose of the invention are more easily conceivable and are of course also included in the scope of the present invention. In addition, in order to make the description clearer, the drawings sometimes schematically represent the width, thickness, shape, etc. of each part compared to the actual method, but after all, it is only an example and does not limit the interpretation of the present invention. In addition, in this specification and the drawings, for the figures that have appeared, the same figure marks are sometimes marked for the same elements as above, and the detailed description is appropriately omitted.

[0041] Hereinafter, a display device according to one embodiment will be described in detail with reference to the drawings.

[0042] In this embodiment, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other, but may intersect at angles other than 90 degrees. The direction toward the tip of the arrow in the third direction Z is defined as upward, and the direction opposite to the tip of the arrow in the third direction Z is defined as downward. Furthermore, the first direction X, the second direction Y, and the third direction Z are sometimes referred to as the X direction, the Y direction, and the Z direction, respectively.

[0043] In the cases where "a second component is above the first component" or "a second component is below the first component," the second component may be in contact with the first component or may be provided separately from the first component. In the latter case, a third component may be interposed between the first and second components. On the other hand, in the cases where "a second component is above the first component" or "a second component is below the first component," the second component is in contact with the first component.

[0044] In addition, assuming that there is an observation position for observing the display device on the front side of the arrow in the third direction Z, the situation of observing from this observation position toward the XY plane defined by the first direction X and the second direction Y is referred to as a plan view. The situation of observing a cross section of the display device in the XZ plane defined by the first direction X and the third direction Z, or in the YZ plane defined by the second direction Y and the third direction Z, is referred to as a cross-sectional view.

[0045] [Implementation Method]

[0046] Figure 1 This is an exploded perspective view schematically showing the structure of a display device including two display panels. Figure 1 A three-dimensional space defined by a first direction X, a second direction Y perpendicular to the first direction X, and a third direction Z perpendicular to the first direction X and the second direction Y is shown.

[0047] like Figure 1 As shown, the display device DSP includes a liquid crystal display panel PNL1, a dimming panel PNL2 and a lighting device ILD. Figure 1 As shown, by disposing the dimming panel PNL2 between the liquid crystal display panel PNL1 and the lighting device ILD, the contrast of the image displayed by the liquid crystal display panel PNL1 can be improved.

[0048] The liquid crystal display panel PNL1 is rectangular in one example. In the example shown in the figure, the short side EX of the liquid crystal display panel PNL1 is parallel to the first direction X, and the long side EY of the liquid crystal display panel PNL1 is parallel to the second direction Y. The third direction Z corresponds to the thickness direction of the liquid crystal display panel PNL1. The main surface of the liquid crystal display panel PNL1 is parallel to the XY plane defined by the first direction X and the second direction Y. The liquid crystal display panel PNL1 has an active area AA1 (display area) and a non-display area NDA located outside the active area AA1. The non-display area NDA1 has a terminal area MT1 for mounting a driver IC and a flexible wiring substrate. Figure 1 In FIG, the terminal region MT1 is indicated by oblique lines.

[0049] The active area AA1 is an area for displaying an image, and includes, for example, a plurality of pixels PX1 arranged in a matrix along the first direction X and the second direction Y. Figure 1As shown in the enlarged view in the middle, each pixel PX1 is arranged in a region partitioned by the scanning line G and the signal line S, and includes a switching element SW, a pixel electrode PE, a common electrode CE, a liquid crystal layer LC, and the like.

[0050] The switching element SW is composed, for example, of a thin film transistor (TFT) and is electrically connected to a scan line G and a signal line S. The scan line G is electrically connected to the switching element SW in each pixel PX1 arranged in the first direction X. The signal line S is electrically connected to the switching element SW in each pixel PX1 arranged in the second direction Y. The pixel electrode PE is electrically connected to the switching element SW. The pixel electrodes PE are each opposed to a common electrode CE, and the liquid crystal layer LC is driven by an electric field generated between the pixel electrodes PE and the common electrodes CE. The capacitor CS is formed, for example, between an electrode having the same potential as the common electrode CE and an electrode having the same potential as the pixel electrode PE.

[0051] The terminal region MT1 extends along the short side EX of the liquid crystal display panel PNL1. Terminal portions are formed in the terminal region MT1, and the liquid crystal display panel PNL1 is electrically connected to an external device such as a flexible wiring board via the terminal portions.

[0052] The dimming panel PNL2 has a structure substantially identical to that of the liquid crystal display panel PNL1. The dimming panel PNL2 includes a plurality of pixels PX2 arranged in a matrix along the first direction X and the second direction Y in the active area AA2 (display area). The structure of the pixels PX2 is identical to that of the pixels PX1, and therefore, the detailed description thereof is omitted by citing the above. In this embodiment, the pixels PX1 and PX2 have the same structure and are the same size. More specifically, the pixels PX1 and PX2 have the same layer structure. Furthermore, the pixels PX1 and PX2 have the same length in each of the first direction X and the second direction Y.

[0053] Like the liquid crystal display panel PNL1, the dimming panel PNL2 includes a non-display area NDA located outside the active area AA2. The non-display area NDA2 includes a terminal area MT2 for mounting a driver IC and a flexible wiring substrate. The non-display area NDA2 and the terminal area MT2 are identical to the non-display area NDA1 and the terminal area MT1, respectively.

[0054] The lighting device ILD is disposed below the dimming panel PNL2 and controls light from the lighting device ILD for each pixel PX, thereby displaying an image. The lighting device ILD of this embodiment is a so-called backlight.

[0055] Figure 2 It is a cross-sectional view schematically showing an example of a display device. Figure 2The display device DSP shown includes a liquid crystal display panel PNL1 , a dimming panel PNL2 , an adhesive layer OCA, a mold frame MFL, an illumination device ILD, a lower frame LFL, and an upper bezel UBZ.

[0056] The lower frame LFL has a bottom portion LFLb and a wall portion LFLa. The bottom portion LFLb has a rectangular shape extending in the XY plane. The wall portion LFLa protrudes from an end portion of the bottom portion LFLb along the third direction Z. The lower frame LFL is formed of, for example, a metal material.

[0057] The mold frame MFL is arranged inside a space formed by the bottom LFLb and the wall LFLa of the lower frame LFL. The wall MFLa of the mold frame MFL is in contact with the wall LFLa of the lower frame LFL. The mold frame MFL is formed of, for example, a resin material.

[0058] The upper frame UBZ has a flat portion UBZa and a wall portion UBZb. The flat portion UBZa has a shape extending in the XY plane. The wall portion UBZb protrudes from the end of the flat portion UBZa along the third direction Z. The upper frame UBZ is formed of, for example, a metal material.

[0059] The liquid crystal display panel PNL1 includes a first substrate SUB1, a second substrate SUB2, a first polarizer PL1, and a second polarizer PL2.

[0060] The liquid crystal layer LC1 is sandwiched between a first substrate SUB1 and a second substrate SUB2, sealed by a sealant. A first polarizer PL1 is disposed below the first substrate SUB1, and a second polarizer PL2 is disposed above the second substrate SUB2. The polarization axes of the first polarizer PL1 and the second polarizer PL2 are, for example, in a cross-Nicol relationship, i.e., at 90 degrees.

[0061] The light modulating plate PNL2 includes a third substrate SUB3, a fourth substrate SUB4, a third polarizing plate PL3, and a fourth polarizing plate PL4.

[0062] The liquid crystal layer LC2 is sandwiched between a third substrate SUB3 and a fourth substrate SUB4 and sealed with a sealant. A third polarizer PL3 is disposed below the third substrate SUB3, and a fourth polarizer PL4 is disposed above the fourth substrate SUB4. The polarization axes of the third polarizer PL3 and the fourth polarizer PL4 are, for example, in a cross-Nicol relationship, i.e., 90 degrees. Alternatively, the polarization axes of the first polarizer PL1 of the liquid crystal display panel PNL1 and the fourth polarizer PL4 of the dimming panel PNL2 can be aligned in the same direction.

[0063] The lighting device ILD includes a reflective sheet REF, a light guide plate LG, and an optical sheet OPS. The reflective sheet REF, the light guide plate LG, and the optical sheet OPS are arranged in this order along the third direction Z. Although not shown, a light source element is arranged facing a side surface of the light guide plate LG.

[0064] The optical sheet OPS is, for example, a prism sheet or a diffusion sheet. Furthermore, for example, two prism sheets and one diffusion sheet may be provided as the optical sheet OPS.

[0065] The reflection sheet REF reflects the light emitted downward from the light guide plate LG and makes the light enter the light guide plate LG again.

[0066] Figure 3 : is a diagram showing a schematic cross-sectional view of a display device of a comparative example. Figure 3 In the display device DSPr shown, pixels PX1 of the liquid crystal display panel PNL1 and pixels PX2 of the dimming panel PNL2 have the same width along the first direction X. Although not shown, the widths of pixels PX1 and PX2 in the second direction Y are also the same.

[0067] The pixel closest to the non-display area NDA1 is set as pixel PX1w. The pixels other than pixel PX1w in pixel PX1 are set as PX1b. The pixel closest to the non-display area NDA2 is set as pixel PX2w. The pixels other than pixel PX2w in pixel PX2 are set as PX2b. Figure 3 1 and 2 show a case where the pixels PX1b and PX2b are displayed in black, and the pixels PX1w and PX2w are displayed in white in the display device DSPr.

[0068] The non-display area NDA includes a light-shielding area BM1 and a light-shielding area BM2. The light-shielding areas BM1 and BM2 may be formed of, for example, a light-shielding material made by dispersing black pigment in a resin material or a light-shielding layer made of a metal material.

[0069] Pixels PX1w and PX2w overlap when viewed from above. Consider a case where an observer observes the display device DSPr from directly above the pixels PX1w and PX2w in a direction opposite to the third direction Z. In this case, the observer's eye is represented by EB1.

[0070] Furthermore, consider a case where an observer observes the display device DSPr from the pixel PX1w in a direction oblique to the third direction Z. In this case, the observer's eye is assumed to be EB2.

[0071] Figure 4 : is a diagram showing a schematic cross-sectional view of a display device of a comparative example. Figure 4In the display device DSPr shown, the boundary between the active area AA1 and the non-display area NDA, and the boundary between the active area AA2 and the non-display area NDA2 do not coincide with each other in a plan view. Figure 4 In the display device DSPr shown, so-called lamination deviation occurs in the liquid crystal display panel PNL1 and the dimming panel PNL2.

[0072] exist Figure 4 For example, the pixel PX1w overlaps with the light-shielding region BM2 in a plan view, and the pixel PX1b adjacent to the pixel PX1w overlaps with the pixel PX2w in a plan view.

[0073] Consider a case where an observer observes the display device DSPr from right above the pixel PX1w in a direction opposite to the third direction Z. In this case, the observer's eye is assumed to be EB3.

[0074] Figures 5 to 7 , the display device DSPr as viewed through eyes EB1, EB2, and EB3 is shown. Figure 5 This is an external view of the display device as viewed by eye EB1. Figure 6 This is an external view of the display device as viewed by eye EB2. Figure 7 This is an external view of the display device as viewed by eye EB3.

[0075] As described above, the non-display area NDA is provided with the light-shielding area BM1, so the viewer perceives the non-display area NDA as black. In the active area AA1, pixel PX1b is displayed in black, so the area occupied by pixel PX1b is perceived as black. The area occupied by pixel PX1w in the active area AA1 is perceived as white. In other words, the area occupied by pixel PX1w, which is displayed in white, is located between the black non-display area NDA and the area occupied by pixel PX1b.

[0076] like Figure 5 As shown, when the display device DSPr is observed as if by the eye EB1, the pixels PX1w and PX2w overlap in a plan view, and thus the regions occupied by the pixels PX1w and PX2w are observed as white frames.

[0077] like Figure 6 As shown, when the display device DSPr is observed by the eye EB2, the light shielding area BM2 of the non-display area NDA2 adjacent to the pixel PX2w is observed through the pixel PX1w. In this case, a part of the area occupied by the pixel PX1w is recognized as black. Figure 6 , the column of pixels PX1w located on the right side of the paper is recognized as black.

[0078] like Figure 7As shown in FIG. 1 , when the display device DSPr is observed by the eye EB3, the light shielding area BM2 of the non-display area NDA2 is observed through the pixel PX1w. Figure 6 Likewise, a portion of the area occupied by the pixel PX1w is recognized as black. Figure 7 , the column of pixels PX1w located on the right side of the paper is also recognized as black.

[0079] like Figure 6 and Figure 7 As shown, if the area that should be perceived as white is perceived as black, that is, if part of the effective area AA1 is missing, the display quality is degraded. In particular, as described using eye EB2, when the effective area AA1 is viewed obliquely with respect to the third direction Z, the display loss becomes noticeable.

[0080] In this embodiment, the pixel PX2 adjacent to the non-display area NDA is positioned not only in the area that overlaps with the active area AA1 when viewed from above, but also in the area that overlaps with the non-display area NDA1. In other words, the active area AA2 extends outside the active area AA1. This prevents display omissions and improves display quality.

[0081] Figure 8 : is a diagram showing a schematic cross-sectional view of a display device according to this embodiment. Figure 8 In the display device DSP shown, the active area AA1 of the liquid crystal display panel PNL1 overlaps with the active area AA2 of the dimming panel PNL2 when viewed from above. The active area AA2 overlaps with the active area AA1 and non-display area NDA1 of the liquid crystal display panel PNL1 when viewed from above. The boundaries between the active area AA1 and the non-display area NDA1, and the boundaries between the active area AA2 and the non-display area NDA2 of the dimming panel PNL2, when viewed from above, do not coincide.

[0082] exist Figure 8 In FIG, three pixels PX2 adjacent to the boundary between the active area AA2 and the non-display area NDA2 are set as pixels PX2w. The same signal is input to the pixels PX2w from the outside. One of the three pixels PX2w overlaps with the pixel PX1w when viewed from above. Figure 8 , the pixel PX2w adjacent to the pixel PX2b overlaps with the pixel PX1w.

[0083] and Figure 3 Similarly, consider a case where an observer observes the display device DSP from right above the pixel PX1 w in a direction opposite to the third direction Z. In this case, the observer's eye is assumed to be EB1.

[0084] Furthermore, consider a case where an observer observes the display device DSP from the pixel PX1 w in a direction oblique to the third direction Z. In this case, the observer's eye is assumed to be EB2.

[0085] When the display device DSP is observed as the eye EB1, Figure 5 Similarly, pixels PX1 w and PX2 w overlap in a plan view, so the area occupied by pixel PX1 w is observed as a white frame.

[0086] When the display device DSP is observed as the eye EB2, Figure 3 Differently, through the pixel PX1w, the pixel PX2w that does not overlap with the pixel PX1w is observed. Since the pixel PX1w and the pixel PX2w are displayed in white, Figure 5 Likewise, the area occupied by pixel PX1w is observed as a white frame. Figure 6 Different, the area occupied by pixel PX1w will not be recognized as black. Figure 8 In the display device DSP shown, even when the display is viewed from a direction tilted with respect to the third direction Z, no display omission occurs.

[0087] Figure 9 : is a diagram showing a schematic cross-sectional view of a display device according to this embodiment. Figure 9 In the Figure 8 In the display device DSP shown in FIG. 1 , a misalignment occurs between the liquid crystal display panel PNL1 and the dimming panel PNL2. Figure 9 In FIG. 4 , the pixel PX1 w overlaps with the pixel PX2 w adjacent to the non-display area NDA among the three pixels PX2 w. Figure 9 The dimming board PNL2 shown is Figure 8 Compared with the dimming plate PNL2 shown, only two pixels PX2 are offset along the first direction X.

[0088] and Figure 4 Similarly, consider a case where an observer observes the display device DSP from directly above the pixel PX1w in a direction opposite to the third direction Z. In this case, the observer's eye is set to EB3. Since the pixel PX1w overlaps with the pixel PX2w, Figure 5 Likewise, the area occupied by pixel PX1w is observed as a white frame. Figure 7 Different, the area occupied by pixel PX1w will not be recognized as black. Figure 9 In the display device DSP shown, even if a misalignment occurs, no display defect occurs.

[0089] exist Figure 9In the example, the pixel PX2w adjacent to the non-display area NDA among the three pixels PX2w overlaps with the pixel PX1w, but this is not limiting. The pixel PX1w may also overlap with the center pixel PX2w among the three pixels PX2w. If one pixel PX1w among the three pixels PX2w overlaps, the white display area will not be lost.

[0090] In this way, even if a misalignment occurs between the liquid crystal display panel PNL1 and the dimming panel PNL2 , display defects can be suppressed and display quality can be improved.

[0091] Figure 10 : is a top view of the display device of this embodiment. Figure 10 , a cross-sectional view of the display device DSP along line A1-A2 is Figure 8 .

[0092] exist Figure 10 In the display device DSP shown, the length of the active area AA1 along the first direction X is shorter than the length of the active area AA2 along the first direction X. The lengths of the active areas AA1 and AA2 along the second direction Y are the same.

[0093] The side EA1y of the active area AA1 extending along the second direction Y is located inside the side EA2y of the active area AA2 extending along the second direction Y. The side EA1x of the active area AA1 extending along the first direction X and the side EA2x of the active area AA2 extending along the first direction X are arranged at the same position.

[0094] Pixel PX1 is provided in active area AA1. Pixel PX2 is provided in active area AA2. The three pixels PX2w are provided between sides EA1y and EA2y in active area AA2. The same signal is input to these three pixels PX2w.

[0095] Figure 11 is a top view showing the configuration of pixels. Figure 11 In order to explain the arrangement of the pixels PX1 and PX2, the pixels PX1 and PX2 that actually overlap are shown separately. Figure 11 As shown, outside the active area AA1, pixels PX2 are arranged in two columns. As described above, since the pixels PX1 and PX2 are the same size, the number of pixels PX2 is twice the number of pixels PX1, that is, four columns.

[0096] In this embodiment, the pixels PX2 of the dimming panel PNL2 are arranged not only in the area overlapping the active area AA1 when viewed from above, but also in the area outside the active area AA1, that is, in the area overlapping the non-display area NDA1. Consequently, no display dropout occurs when the display device DSP is viewed from a direction parallel to the third direction Z or from a direction inclined relative to the third direction Z. Furthermore, even if alignment misalignment occurs between the liquid crystal display panel PNL1 and the dimming panel PNL2, no display dropout occurs due to the overlapping pixel PX2 on the pixel PX1. As described above, the display device DSP of this embodiment can suppress display dropout and improve display quality.

[0097] <Structure Example 1>

[0098] Figure 12 : is a cross-sectional view showing another structural example of the display device in the embodiment. Figure 12 In the structural example shown, Figure 8 Compared with the illustrated configuration example, the width of the pixel PX2 adjacent to the non-display area NDA2 among the pixels PX2 of the dimming panel PNL2 is different in that the width of the pixel PX2 is longer than the width of the other pixels PX2.

[0099] Among the pixels PX2 of the dimming panel PNL2, the pixel PX2w adjacent to the non-display area NDA2 has a longer length (width) along the first direction X than the other pixel PX2b located in the active area AA2. Pixels PX1 and PX2b have the same width. If the lengths (widths) of pixels PX1, PX2b, and PX2w along the first direction X are w1 and w2, respectively, then w2 is longer than w1 (w2>w1). Pixels PX1, PX2b, and PX2w have the same length along the second direction Y.

[0100] Here, consider a case where the observer observes the display device DSP from a direction tilted relative to the third direction Z. For example, even if the display device DSP is observed from a direction tilted 45° relative to the third direction Z, the condition for no display omission is set to the minimum value of the width w2.

[0101] Figure 13 yes Figure 12 A partially enlarged view. Let gp1 be the distance (length) between pixels PX1 and PX2 along the third direction Z. In the above case, to prevent display omission, the width w2 of pixel PX2w can be made longer by a length gp1 than the width w1 of pixel PX2b. In other words, width w2 only needs to be the sum of width w1 and length gp1 (w2 = w1 + gp1).

[0102] Figure 14 is a top view showing the configuration of pixels. Figure 14 In, with Figure 11 Similarly, in order to explain the arrangement of the pixels PX1 and PX2, the pixels PX1 and PX2 that actually overlap are shown separately. Figure 14 As shown, the column of pixels PX2w having a width w2 protrudes to the outside of the active area AA1.

[0103] and Figure 11 Different, in Figure 14 In this configuration example, the number of pixels PX1 and PX2 is the same. In this configuration example, by extending the width of the pixel PX2w, the same effect as in the embodiment is achieved.

[0104] <Structure Example 2>

[0105] Figure 15 : is a cross-sectional view showing another structural example of the display device in the embodiment. Figure 15 In the structural example shown, Figure 8 Compared with the illustrated structural example, the difference lies in that pixel units PX2U are provided on the dimming panel PNL2 corresponding to the plurality of pixels PX1 of the liquid crystal display panel PNL1.

[0106] exist Figure 15 In the display device DSP shown, the dimming panel PNL2 includes pixel units PX2U. One pixel unit PX2U corresponds to three pixels PX1 of the liquid crystal display panel PNL1. The dimming panel PNL2 only needs to transmit light to the liquid crystal display panel PNL1; the fineness does not need to match that of the liquid crystal display panel PNL1. Therefore, in this exemplary configuration, the fineness of the dimming panel PNL2 is set to one-third that of the liquid crystal display panel PNL1.

[0107] The pixel unit PX2Uw adjacent to the non-display area NDA2 overlaps with the pixel PX1w and the non-display area NDA1. Compared with the other pixel units PX2Ub, the pixel unit PX2Uw has a width longer than the pixel PX1.

[0108] exist Figure 15 , the lengths (widths) of the pixel PX1, pixel units PX2Ub, and PX2Uw along the first direction X are w1, w2ub, and w2uw, respectively. The width w2uw is four times the width w1 (w2uw=4w1), and the width w2ub is three times the width w1 (w2ub=3w1).

[0109] Figure 16 : is a top view showing the arrangement of pixels of this structural example. Figure 16 In, with Figure 11Similarly, in order to illustrate the arrangement of the pixel PX1 and the pixel unit PX2U, the pixel PX1 and the pixel unit PX2U that actually overlap are shown separately. Figure 16 As shown, the column of pixel units PX2Uw having a width w2uw protrudes outside the active area AA1.

[0110] This configuration example also produces the same effects as those of the embodiment.

[0111] In the present disclosure, the pixels PX1 and PX2 are also referred to as first and second pixels, respectively. The pixel PX2w disposed adjacent to the non-display area NDA2 is also referred to as an outermost pixel.

[0112] In this disclosure, Figure 15 and Figure 16 The pixel unit PX2U shown is also referred to as a second pixel unit. The pixel unit PX2Uw adjacent to the non-display area NDA2 is also referred to as an outermost pixel unit.

[0113] While several embodiments of the present invention have been described, these embodiments are provided as examples and are not intended to limit the scope of the invention. These new embodiments may be implemented in various other ways, and various omissions, substitutions, and modifications may be made without departing from the gist of the invention. These embodiments and their variations are intended to be within the scope and gist of the invention and are encompassed by the invention as set forth in the claims and their equivalents.
