A display system is provided with: a display device having a plurality of pixels arranged in a matrix on a substrate; and a surface layer covering the display device and having a semi-transmissive layer and a plurality of openings provided in the semi-transmissive layer, the plurality of pixels including pixels provided overlapping the semi-transmissive layer and pixels provided overlapping the openings.

Description

Technical Field

[0001] This disclosure relates to display systems. Background Technology

[0002] In recent years, it has become known to have operation display panels with touch sensors embedded in articles, in which a thin wood veneer made of natural wood or the like is placed on top of a display panel (see, for example, Patent Document 1). In Patent Document 1, the thin wood veneer is located on the outer surface of the operation display panel embedded in the article, and an array of LED light sources is located inside the article. It is possible to visually observe text or patterns composed of light emitted from the array of LED light sources through the thin wood veneer.

[0003] In Patent Document 2, multiple inorganic light-emitting elements are respectively arranged overlapping multiple transmissive portions provided on the surface layer. Therefore, when the inorganic light-emitting elements of the display device are lit, light from the inorganic light-emitting elements is transmitted through the transmissive portions that are opposite to the upper side of the inorganic light-emitting elements and illuminates the outside of the display device.

[0007] Patent Document 2: JP 2021-39281 Summary of the Invention

[0008] In Patent Document 1, the display panel is embedded in an article. The displayed image of text or patterns composed of LED light sources, which can be viewed through a thin wooden board, has reduced resolution in the display state, and the displayed image may become blurry. Therefore, the display image of text or patterns in Patent Document 1 is limited to applications where the resolution is insufficient to present and convey the illumination state of the LED using only dots.

[0009] In Patent Document 2, compared to Patent Document 1, light from the LED light source can be emitted to the outside through the transmissive portion, thus enabling clear identification of the displayed image. However, in the technology of Patent Document 2, increasing the number of transmissive portions is also necessary to improve resolution. In Patent Document 2, the aim is to suppress the number of transmissive portions and improve the contrast of the displayed image relative to the texture of the thin wood panel surface.

[0010] The purpose of this disclosure is to provide a display system that can improve the visual visibility of the displayed image and increase the contrast of the displayed image.

[0011] A display system according to one aspect of this disclosure includes: a display device having a plurality of pixels arranged in a matrix on a substrate; and a surface layer covering the display device and having a semi-transparent layer and a plurality of openings provided in the semi-transparent layer, the plurality of pixels including pixels disposed overlapping the semi-transparent layer and pixels disposed overlapping the openings.

[0037] Referring to the accompanying drawings, the methods for carrying out the invention (implementation methods) are described in detail below. This disclosure is not limited to the content described in the following embodiments. Furthermore, the constituent elements described below include constituent elements readily conceived by those skilled in the art, as well as substantially the same constituent elements. Moreover, the constituent elements described below can be appropriately combined. It should be noted that this disclosure is merely an example, and appropriate modifications that maintain the spirit of the invention and are readily conceived by those skilled in the art are naturally included within the scope of this disclosure. Additionally, to make the description clearer, the width, thickness, shape, etc., of various parts of the drawings are sometimes schematically shown compared to the actual form, but this is merely an example and does not limit the interpretation of this disclosure. Furthermore, in this specification and the various figures, the same reference numerals are used for elements that are the same as those described with respect to the already presented drawings, and detailed descriptions are sometimes appropriately omitted.

[0038] In this specification and the scope of patent protection, when describing the configuration of other structures on a certain structure, unless otherwise specified, the use of the phrase "on" includes both the case of other structures being configured directly above a certain structure in a manner connected to it, and the case of other structures being configured with another structure interposed above a certain structure.

[0039] (Implementation Method 1)

[0040] Figure 1 This is a schematic diagram of the display system of this embodiment. For example... Figure 1As shown, the display system 1 of this embodiment includes a display device 100 and a surface layer 5. The surface layer 5 is, for example, a veneer or plywood made of wood, or a thin wood panel obtained by molding wood chips (wood shavings), and the surface of the surface layer 5 has, for example, a wood grain texture. When it is made of wood, paulownia, maple, cherry, or walnut can be selected, but it is not limited to these. In addition, the thickness of the surface layer 5 is 0.2 mm to 0.5 mm.

[0041] The display device 100 is mounted on the surface layer 5 and is used to display images. The display device 100 is disposed on the back side of the surface layer 5.

[0042] Hereinafter, a direction parallel to the surface of surface layer 5 is designated as the first direction Dx, and another direction parallel to the surface is designated as the second direction Dy. The first direction Dx is orthogonal to the second direction Dy, but it may also intersect the second direction Dy instead of being orthogonal to it. Furthermore, a direction orthogonal to both the first and second directions Dx, that is, a direction orthogonal to the surface of surface layer 5, is designated as the third direction Dz. The third direction Dz, for example, corresponds to the normal direction of the first substrate 71 described later. Hereinafter, "top view" refers to the positional relationship when viewed from the third direction Dz. Additionally, one direction parallel to the third direction Dz is designated as direction Dz1, and another direction parallel to the third direction Dz, that is, the direction opposite to direction Dz1, is designated as direction Dz2. Direction Dz1 is the direction from the array substrate SUB1 described later toward the surface of surface layer 5.

[0043] Figure 2 This is a schematic top view of the display device according to this embodiment. Figure 2 As shown, the display device 100 includes a display panel 2.

[0044] like Figure 2 As shown, the display device 100 has a display area AA and a peripheral area GA. The display area AA is an area for arranging a plurality of pixels 48 and is an area for displaying an image. The peripheral area GA is an area that does not overlap with the plurality of pixels 48 and is arranged outside the display area AA. The plurality of pixels 48 in the display area AA are arranged, for example, in a matrix in the first direction Dx and the second direction Dy.

[0045] Each of the pixels 48 has, for example, a first sub-pixel 49R, a second sub-pixel 49G, and a third sub-pixel 49B. The first sub-pixel 49R displays the first primary color (e.g., red). The second sub-pixel 49G displays the second primary color (e.g., green). The third sub-pixel 49B displays the third primary color (e.g., blue).

[0046] Subpixel 49R, subpixel 49G, and subpixel 49B are arranged in this order along the first direction Dx and the second direction Dy. This arrangement of subpixel 49R, subpixel 49G, and subpixel 49B is called a striped arrangement. Hereinafter, without distinguishing between subpixel 49R, subpixel 49G, and subpixel 49B, they may sometimes be simply referred to as "subpixel 49". It should be noted that the arrangement of subpixel 49 is not limited to a striped arrangement.

[0047] The surface layer 5, when viewed from above, covers the entire area of ​​the display device 100, including the display area AA and the peripheral area GA. The surface layer 5 includes a translucent semi-transparent layer 51 and multiple openings OP formed in the semi-translucent layer 51. The semi-translucent layer 51 is a layer with a light transmittance of 1% to 50%, for example, the light transmittance of Embodiment 1 is about 3.5%.

[0048] In addition, surface layer 5 is surface treated by coating before sandblasting. This helps to suppress the surface roughness of surface layer 5.

[0049] like Figure 2 As shown, a plurality of openings OP are provided in the surface layer 5. In this embodiment, the opening OP is an opening (hole) provided from the surface of the surface layer 5 in direction Dz2 to the surface in direction Dz1. The openings OP are arranged at predetermined intervals along the first direction Dx and the second direction Dy. At least one of the sub-pixels 49 is arranged at a position where a portion of the sub-pixel 49 overlaps with the opening OP.

[0050] Furthermore, in this embodiment, the multiple openings OP are arranged in a square grid pattern when viewed from above. It should be noted that... Figure 2 The configuration and number of the multiple openings (OPs) shown are merely examples and can be varied appropriately. The multiple openings (OPs) can also be configured to appear as a rhomboid or rectangular grid when viewed from above.

[0051] This allows the light transmittance to be increased to between 5% and 20%, improving the visual visibility of the displayed image.

[0052] Here, the diameter of the opening OP in a top-down view is defined as diameter D1. The diameter D1 of the opening OP is 50 μm or more and 100 μm or less.

[0053] Therefore, the opening OP can be easily formed and is not easily observed visually. The diameter D1 is the diameter of the opening OP in the second direction Dy, or it can be the diameter of the opening OP in the first direction Dx.

[0054] Here, the spacing between the openings OP in a top-down view is defined as spacing D2. Spacing D2 is the length connecting the center points of adjacent openings OP in the second direction Dy. Spacing D2 is between 100 μm and 200 μm.

[0055] Therefore, when the user visually observes surface layer 5, the opening OP is not easily visible, which improves light transmittance. The spacing D2 can also be the length connecting the center points of adjacent openings OP in the first direction Dx.

[0056] Table 1 shows the relationship between the diameter of the opening OP, the aperture ratio, and the spacing between the opening OPs. Here, the aperture ratio represents the proportion of the display area AA occupied by the opening OP.

[0057] As shown in Table 1, the larger the opening ratio, the narrower the spacing between the openings (OPs). Conversely, the larger the diameter of the openings (OPs), the wider the spacing.

[0058] It should be noted that, in order to form the opening OP in the shortest possible time, it is preferable to have a wide spacing between the opening OPs. In this case, it is preferable that the spacing between the opening OPs is 150μm or more and 200μm or less, and the opening ratio is 10% or more and 15% or less.

[0059] This improves the productivity of the opening section (OP). Furthermore, the increased light transmittance also improves the resolution of the displayed image.

[0060] Table 1

[0061] (Table 1)

[0062]

[0063] Table 2 shows the relationship between the density of opening OPs and the spacing of the opening OPs. Here, the density of opening OPs is the number of opening OPs per foot, and the unit of the density of opening OPs is dpi.

[0064] As shown in Table 2, the narrower the spacing between the opening OPs, the greater the density of the opening OPs. It should be noted that since the resolution of the displayed image decreases below 100 dpi, and the spacing becomes too small above 250 dpi, making it difficult to form opening OPs, the density of opening OPs is preferably between 100 dpi and 250 dpi.

[0065] Therefore, a higher resolution of the displayed image can improve visual observation.

[0069] Figure 3 This is a block diagram illustrating an example of the configuration of the display device of embodiment 1. For example... Figure 3 As shown, the display device 100 of Embodiment 1 includes a signal processing unit 10, a display unit 20, a light source device 50, and a light source control circuit 60. The display unit 20 includes a display panel driving unit 40 and a display panel 2. The signal processing unit 10 performs various outputs based on the input signal IS input from an external control device 200, controlling the operation of the display unit 20 and the light source device 50. The input signal IS is a signal that functions as data for causing the display device 100 to display an output image, such as an RGB image signal. The input signal IS corresponds to the resolution of the display panel 2. That is, the input signal IS includes the number of pixels 48 of the display panel 2 (described later) and pixel signals corresponding to the configuration of the first direction Dx and the second direction Dy. The signal processing unit 10 outputs the output image signal OS generated based on the input signal IS to the display unit 20. In addition, when the input signal IS is input, the signal processing unit 10 outputs a light source driving signal BL for controlling the illumination of the light source device 50 to the light source control circuit 60. The light source control circuit 60 is, for example, a driver circuit for the light source device 50, which activates the light source device 50 according to the light source drive signal BL. The light source device 50 has a light source that emits light from the light-emitting area LA. In Embodiment 1, the light source control circuit 60 activates the light source device 50 so that a certain amount of light is emitted from the light-emitting area LA of the light source device 50 according to the display timing of the frame image.

[0070] The display unit 20 includes a display panel 2 and a display panel driving unit 40. The display panel 2 has a display area AA with a plurality of pixels 48. The plurality of pixels 48 are arranged in a matrix, for example. The display panel 2 in Embodiment 1 is a liquid crystal image display panel. The display panel driving unit 40 includes a signal output circuit 41 and a scanning circuit 42. The signal output circuit 41 is a circuit that functions as a source driver and drives the plurality of pixels 48 according to the output image signal OS. The scanning circuit 42 is a circuit that functions as a gate driver and outputs a driving signal that scans the plurality of pixels 48 arranged in a matrix in units of a specified row (for example, 1 row). The pixels 48 are driven to output grayscale values ​​corresponding to the output image signal OS at the timing when the driving signal is output.

[0071] The light source device 50 is disposed on the back of the display unit 20. The light source device 50 illuminates the display unit 20 by shining light toward it.

[0072] Figure 4This is a diagram illustrating an example of the pixel arrangement of display panel 2. (As shown...) Figure 4 As shown, the pixels 48 arranged in a matrix on the display panel 2 include a first sub-pixel 49R displaying a first color, a second sub-pixel 49G displaying a second color, and a third sub-pixel 49B displaying a third color. The first, second, and third colors are not limited to primary colors; they only need to be different in complementary colors or the like. In the following description, when it is not necessary to distinguish between the first sub-pixel 49R, the second sub-pixel 49G, and the third sub-pixel 49B, they will be referred to as sub-pixels 49.

[0073] It should be noted that, in addition to the first sub-pixel 49R, the second sub-pixel 49G, and the third sub-pixel 49B, pixel 48 may also have a sub-pixel 49. For example, pixel 48 may also have a fourth sub-pixel displaying a fourth color. The fourth sub-pixel displays a fourth color (e.g., white). When illuminated by the same amount of light source, the fourth sub-pixel is preferably brighter than the first sub-pixel 49R displaying the first color, the second sub-pixel 49G displaying the second color, and the third sub-pixel 49B displaying the third color.

[0074] The display panel 2 is, for example, a transmissive color liquid crystal display panel. A first color filter that allows light of the first primary color to pass through is disposed between the first sub-pixel 49R and the image observer; a second color filter that allows light of the second primary color to pass through is disposed between the second sub-pixel 49G and the image observer; and a third color filter that allows light of the third primary color to pass through is disposed between the third sub-pixel 49B and the image observer.

[0075] The signal output circuit 41 is electrically connected to the display panel 2 via the signal line DTL. The display panel driving unit 40 uses the scanning circuit 42 to select the sub-pixels 49 in the display panel 2 and controls the on / off state of the switching elements (e.g., thin film transistors (TFTs)) used to control the operation (light transmittance) of the sub-pixels 49. The scanning circuit 42 is electrically connected to the display panel 2 via the scan line SCL.

[0076] Figure 5 This is a schematic partial cross-sectional view of the display system of Embodiment 1. For example... Figure 5 As shown, the display device 100 includes an array substrate SUB1, an opposing substrate SUB2, and a liquid crystal layer LC. The surface layer 5 has a first surface 510 and a second surface 511 opposite to the first surface 510. The opening OP is provided such that it extends from the second surface 511 through the first surface 510.

[0077] The array substrate SUB1 includes a first substrate 71, which is a light-transmitting substrate such as glass; a first alignment film 62 stacked on one side of the liquid crystal layer LC on the first substrate 71; a plurality of pixel electrodes PE covered by the first alignment film 62; and a first polarizer 63 stacked on the side of the first substrate 71 opposite to the liquid crystal layer LC. The first alignment film 62 aligns the liquid crystal molecules in the liquid crystal layer LC in a predetermined direction and is in direct contact with the liquid crystal layer LC. The first alignment film 62 is, for example, polyimide and has undergone rubbing treatment or photoalignment treatment. The first polarizer 63 has the function of converting light incident from the light source device 50 disposed on the back side of the display device 100 into linearly polarized light.

[0078] The opposing substrate SUB2 includes a second substrate 68 that is an insulating substrate with light transmittance, such as glass, a color filter CF formed on the liquid crystal layer LC side of the second substrate 68, a second alignment film 67 formed on the liquid crystal layer LC side of the color filter CF, a common electrode CE covered by the second alignment film 67, and a second polarizer 69 formed on the side of the second substrate 68 opposite to the liquid crystal layer LC side.

[0079] The common electrode CE is configured to span across two adjacent pixel electrodes PE. Each pixel electrode PE overlaps with a color filter CF. Both the pixel electrodes PE and the common electrode CE are transparent.

[0080] A color filter CF is configured, for example, with a periodically arranged first sub-pixel 49R, second sub-pixel 49G, and third sub-pixel 49B. Pixel 48 includes three sub-pixels 49, and each pixel 48 is associated with a group of three color regions of 49R, 49G, and 49B. It should be noted that a color filter CF can include more than four color regions. In this case, pixel 48 can also include four or more sub-pixels 49.

[0081] It should be noted that the display device 100 may also be provided with a cover component formed of a glass substrate or a resin substrate, a touch panel, or a detection device, as needed.

[0082] The plurality of pixels 48 include pixels 48 that overlap with the translucent layer 51 and pixels 48 that overlap with the opening OP.

[0083] The light L transmitted from pixel 48 has a first light L1 and a second light L2. The first light L1 is the light transmitted from pixel 48, which overlaps with the semi-transparent layer 51, and the semi-transparent layer 51. The second light L2 is the light transmitted from pixel 48, which overlaps with the opening OP, and the opening OP. Thus, the user can visually observe the first light L1 and the second light L2 in a composite manner.

[0084] Next, the appearance of display system 1 will be described under visual observation. Figure 6 This is a schematic diagram showing the appearance of a display system when the display device is not emitting light. Figure 7 This is a schematic diagram showing the appearance of a display system when the display device emits light.

[0085] like Figure 6 As shown, when the display device 100 does not emit light to the surface layer 5, the pixel 48 does not emit light. Therefore, when viewing the display system 1 from above when the display device 100 is not emitting light, the surface layer 5 is visually observed, but the display device 100 (display panel 2) is not visually observed by the user.

[0086] In addition, the opening OP of the surface layer 5 is small enough to be difficult to observe visually, so the opening OP will not be observed by the user.

[0087] On the other hand, light from the light source device 50 reaches the user through the sub-pixel 49. For example... Figure 7 As shown, the user visually observes the light emitted from the light source device 50 and passing through the display panel 2, thereby visually observing the image output by the display panel 2.

[0088] When the display device 100 emits light to the surface layer 5, the light transmitted through the pixel 48 is transmitted through the opening OP and the semi-transparent layer 51, which are opposite to the direction Dz1 of the pixel 48, and irradiates the outside ER of the display device 100.

[0089] The display panel 2 displays a display image PI on the surface layer 5 in the direction Dz1 using a first light L1 transmitted through the semi-transparent layer 51 and a second light L2 transmitted through the opening OP. The display image PI has a background image P1 and a pattern image P2.

[0090] Therefore, even without increasing the number of openings OP, the contrast of the displayed image P1 can be improved relative to the texture such as wood grain in the surface of the surface layer 5, thus improving the visual visibility of the displayed image. For example, users can easily identify the background image P1 relative to the texture such as wood grain in the surface of the surface layer 5, and can visually observe the pattern image P2 more clearly by comparing it with the background image P1.

[0091] (First variation of Implementation Method 1)

[0092] Figure 8 This is a schematic partial cross-sectional view of the display system of the first variation of Embodiment 1. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0093] like Figure 8As shown, the display system 1A of the first modification of Embodiment 1 includes a display device 100 and a surface layer 5A. The surface layer 5A has a plurality of openings OP, and the shape of the openings OP is conical when viewed in cross-section. The diameter of the openings OP in the first surface 510 is 50 μm, and the diameter of the openings OP in the second surface 511 is 100 μm.

[0094] With the surface layer 5A having a thickness of 0.2 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 14.0°.

[0095] With the surface layer 5A having a thickness of 0.3 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 9.5°.

[0096] With the surface layer 5A having a thickness of 0.4 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 7.1°.

[0097] With the surface layer 5A having a thickness of 0.5 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 5.7°.

[0098] The maximum value of the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 14°.

[0099] Therefore, the second light L2, which enters through the wide opening in the second surface 511 of the opening OP, exits through the narrow opening in the first surface 510 of the opening OP, thereby increasing the brightness.

[0100] (Second variation of Implementation Method 1)

[0101] Figure 9 This is a schematic partial cross-sectional view of the display system of the second variation of Embodiment 1. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0102] like Figure 9 As shown, the display system 1B of the second modification of Embodiment 1 includes a display device 100 and a surface layer 5B. The surface layer 5B has a plurality of openings OP, which are inverted conical in shape when viewed in cross-section. The diameter of the opening OP in the first surface 510 is 100 μm, and the diameter of the opening OP in the second surface 511 is 50 μm.

[0103] With the surface layer 5B having a thickness of 0.2 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 14.0°.

[0104] With the surface layer 5B having a thickness of 0.3 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 9.5°.

[0105] With the surface layer 5B having a thickness of 0.4 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 7.1°.

[0106] With the surface layer 5B having a thickness of 0.5 mm, the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 5.7°.

[0107] The maximum value of the angle θ between the vertical direction of the display device 100 and the side 52 of the opening OP is 14°.

[0108] As a result, the second light L2, which enters through the narrow opening in the second surface 511 of the opening OP, exits through the wide opening in the first surface 510 of the opening OP. Therefore, the overall display image becomes brighter, which improves the visual visibility of the display image.

[0109] (Implementation Method 2)

[0110] Figure 10 This is a schematic partial cross-sectional view of the display system according to Embodiment 2. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0111] like Figure 10 As shown, the display system 1C of Embodiment 2 includes a display device 100 and a surface layer 5C. The surface layer 5C also includes a protective film 80 that protects the opening OP.

[0112] The protective film 80 is made of a light-transmitting resin. Each opening OP is filled with the protective film 80.

[0113] Therefore, reducing the surface roughness of surface layer 5C can improve the tactile feel of surface layer 5C.

[0114] (First variation of implementation method 2)

[0115] Figure 11 This is a schematic partial cross-sectional view of the display system of the first variation of Embodiment 2. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0116] like Figure 11As shown, the display system 1D of the first modification of Embodiment 2 includes a display device 100 and a surface layer 5D. The surface layer 5D also includes a protective film 80 that protects the openings OP. The plurality of openings OP are filled by the protective film 80, and the outer peripheral surface of the surface layer 5D is covered by the protective film 80.

[0117] Therefore, it can protect the entire surface of the 5D surface layer and improve the strength of the 5D surface layer.

[0118] It should be noted that the protective film 80 may also contain additives that prevent static electricity. In this case, the anti-static properties can be improved, and the generation of static electricity can be suppressed.

[0119] (Second variation of implementation method 2)

[0120] Figure 12 This is a schematic partial cross-sectional view of the display system of the second variation of Embodiment 2. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0121] like Figure 12 As shown, the display system 1E of the second modification of Embodiment 2 includes a display device 100 and a surface layer 5E. The surface layer 5E also includes a protective film 80 that protects the opening OP. The surface of the surface layer 5E is covered by the protective film 80.

[0122] Therefore, the surface of surface layer 5E can be protected, and the strength of surface layer 5E can be improved.

[0123] (Implementation Method 3)

[0124] Figure 13 This is a schematic partial cross-sectional view of the display system according to Embodiment 3. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0125] like Figure 13 As shown, the display system 1F of Embodiment 3 includes a display device 100 and a surface layer 5F. A plurality of pixels 48 include pixels 48 that overlap with recesses 51a and pixels 48 that overlap with a translucent layer 51 that does not have recesses 51a. The surface layer 5F has a plurality of recesses 51a recessed from a first surface 510 toward a second surface 511.

[0126] The transmittance of the recess 51a becomes greater than the transmittance of light around the recess 51a. The light L transmitted from the pixel 48 has a first light L1 and a second light L2. The first light L1 is the light transmitted from the pixel 48 that overlaps with the semi-transparent layer 51 that does not have the recess 51a, as well as the semi-transparent layer 51 that does not have the recess 51a. The second light L2 is the light transmitted from the pixel 48 that overlaps with the recess 51a, as well as the recess 51a. Thus, the user can visually observe the first light L1 and the second light L2 in a composite manner.

[0127] It should be noted that the function and effect of the display system 1F in Embodiment 3 are the same as those of the display system 1 in Embodiment 1, and therefore are omitted.

[0128] (A variation of implementation method 3)

[0129] Figure 14 This is a schematic partial cross-sectional view of the display system of a variation of Embodiment 3. It should be noted that in the following description, the same reference numerals are used for the same constituent elements as those described in the above embodiments, and repeated descriptions are omitted.

[0130] like Figure 14 As shown, the display system 1G of the modified embodiment 3 includes a display device 100 and a surface layer 5G. The plurality of pixels 48 includes pixels 48 that overlap with recesses 51b and pixels 48 that overlap with a translucent layer 51 that does not have recesses 51b. The surface layer 5G has a plurality of recesses 51b recessed from the second surface 511 toward the first surface 510.

[0131] The transmittance of the recess 51b becomes greater than the transmittance of light around the recess 51b. The light L transmitted from the pixel 48 has a first light L1 and a second light L2. The first light L1 is the light transmitted from the pixel 48 that overlaps with the semi-transparent layer 51 that does not have a recess 51b, as well as the semi-transparent layer 51 that does not have a recess 51b. The second light L2 is the light transmitted from the pixel 48 that overlaps with the recess 51b, as well as the recess 51b. Thus, the user can visually observe the first light L1 and the second light L2 in a composite manner.

[0132] It should be noted that the function and effect of the display system 1G in the modified example of embodiment 3 are the same as those of the display system 1 in embodiment 1, and therefore are omitted.

[0133] Furthermore, regarding other effects resulting from the configuration described in this embodiment, it should be understood that the effects clearly obtained from the description in this specification, or the effects that can be reasonably conceived by those skilled in the art, are of course brought about by this disclosure.
