Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional display panel unit, the touch panel disposed in front of the display panel is attached to the frame body by attaching the end portion of the touch panel to the stepped portion of the side surface portion of the frame body with a double-sided tape. In the display panel unit having such a structure, for example, when a strong impact is applied from the front of the touch panel, the end portion of the touch panel may be peeled off from the frame body, and the glass component of the display panel may be damaged. In this case, due to the breakage of the glass component, a large number of fine glass fragments (glass pieces) are scattered, and there is a possibility that these glass pieces flow out to the outside from the gap between the end portion of the touch panel and the frame body. In order to prevent this, it is conceivable to make it difficult for the end portion of the touch panel to come off the frame body by increasing the adhesion area between the end portion of the touch panel and the frame body. However, at present, there is a demand for a narrow bezel in a display device such as the display panel unit, and in order to meet this requirement, there is also a situation where it is difficult to increase the adhesion area. In particular, since an aircraft is likely to experience unexpected large shakes during flight, a problem for a display device used in an aircraft is how to suppress the outflow of the above-described glass pieces to the outside when an excessive impact is applied.

[0005] The present disclosure has been made by the inventors of the present application newly focusing on the above problems, and provides a display device with improved safety.

Means for Solving the Problems

[0006] A display device according to an aspect of the present disclosure is a display device used in an aircraft, and includes a first panel having light transmissivity, a second panel that faces a first back surface that is the back surface of the first panel and displays an image on the front surface, the second panel including a glass substrate, a housing that forms a housing space for housing the second panel and has a side wall portion that supports a peripheral portion of the first panel, and a shielding member having one end connected to the peripheral portion of the first panel, the shielding member having a portion that extends rearward from the peripheral portion inside the housing space.

Effects of the Invention

[0007] According to the present disclosure, a display device with improved safety can be provided.

Embodiments for Carrying Out the Invention

[0009] The display device according to the first aspect of the present disclosure is a display device used in an aircraft, and includes a first panel having light transmissibility, a second panel that faces the first back surface, which is the back surface of the first panel, and displays an image on the front surface, the second panel including a glass substrate, a housing that forms a housing space for housing the second panel and has a side wall portion that supports a peripheral portion of the first panel, and a shielding member having one end connected to the peripheral portion of the first panel and having a portion that extends rearward from the peripheral portion inside the housing space.

[0010] According to the display device according to the first aspect, even when, for example, due to an excessive impact, the peripheral portion of the first panel comes off the housing and the glass substrate of the second panel is cracked, a shielding member having a portion that extends rearward is disposed at the peripheral portion of the first panel. Therefore, it is possible to suppress glass pieces from flowing out of the housing through the gap between the peripheral portion of the first panel and the housing. Accordingly, the display device according to the present aspect is a display device with improved safety.

[0011] The display device according to the second aspect of the present disclosure may be the display device according to the first aspect, wherein the other end of the shielding member is located rearward of the second back surface, which is the back surface of the second panel.

[0012] According to the display device according to the second aspect, since the length of the shielding member in the front-rear direction is relatively large, it is possible to more reliably suppress the outflow of glass pieces through the gap between the peripheral portion and the housing when the peripheral portion of the first panel comes off the housing.

[0013] The display device according to the third aspect of the present disclosure may be the display device according to the second aspect, wherein the housing has an opposing wall portion that opposes the second back surface, and the other end is located between the second back surface and the opposing wall portion.

[0014] According to the display device according to the third aspect, the shielding member is formed to have a size extending from the peripheral edge of the first panel to the back surface (second back surface) of the second panel. Therefore, the effect of suppressing the outflow of glass pieces through the gap between the peripheral edge of the first panel and the housing by the shielding member is further improved.

[0015] The display device according to the fourth aspect of the present disclosure may be the display device according to the third aspect, wherein the shielding member includes a buffer member that is a portion extending rearward from the peripheral edge, and a plate-like member that is connected to the buffer member and has the other end.

[0016] According to the display device according to the fourth aspect, when the first panel is deformed by an impact, the buffer member is likely to follow the deformation. Therefore, for example, problems such as the shielding member coming off from the peripheral edge due to the deformation are less likely to occur. That is, the effect of suppressing the outflow of glass pieces by the shielding member is more reliably achieved.

[0017] The display device according to the fifth aspect of the present disclosure may be the display device according to any one of the first to fourth aspects, wherein the shielding member is disposed at at least one of the peripheral edge at the upper end portion and the peripheral edge at the lower end portion of the first panel.

[0018] According to the display device according to the fifth aspect, for example, the shielding member is disposed at at least one of the upper and lower end portions, which are portions of the horizontally long first panel that are likely to come off from the housing. Therefore, the effectiveness of the effect of suppressing the outflow of glass pieces by the shielding member is improved.

[0019] The display device according to the sixth aspect of the present disclosure may be the display device according to the fifth aspect, wherein the housing has two mounting portions that are portions where other objects to be disposed behind the housing are mounted, the two mounting portions are spaced apart in the left-right direction, and the arrangement range of the shielding member in the left-right direction includes the range between the two mounting portions in the left-right direction.

[0020] According to the display device according to the sixth aspect, the shielding member is disposed in a range where the first panel is likely to be deformed by an external force received from the front. Therefore, the effectiveness of the shielding member in suppressing the outflow of glass pieces is improved.

[0021] The display device according to the seventh aspect of the present disclosure may be the display device according to the fifth or sixth aspect, wherein the shielding member is disposed in a range including the center of the housing in the left-right direction and covering a range of 1 / 3 or more and 1 / 2 or less of the total length of the housing in the left-right direction.

[0022] According to the display device according to the seventh aspect, the shielding member is disposed in a range centered on the central portion of the first panel that is less likely to come off from the housing. Therefore, the outflow of glass pieces through the gap between the peripheral edge portion of the first panel and the housing is more efficiently suppressed by the shielding member.

[0023] The display device according to the eighth aspect of the present disclosure may be the display device according to any one of the first to seventh aspects, wherein the other end of the shielding member is a free end.

[0024] According to the display device according to the eighth aspect, since the shielding member only needs to be connected to the peripheral edge portion of the first panel, the assembly of the display device including the shielding member is easy.

[0025] Furthermore, the additional advantages and effects in one aspect of the present disclosure are clarified from the specification and the drawings. Such advantages and / or effects are provided by some embodiments and the configurations described in the specification and the drawings, but not necessarily all configurations are required.

[0026] Hereinafter, embodiments will be specifically described with reference to the drawings. The embodiments described below all show comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are merely examples and not intended to limit the present invention. Among the components in the following embodiments, components not described in the independent claims indicating the most general concept are described as optional components. Each figure is a schematic diagram and is not necessarily drawn precisely. In each figure, the same constituent members are denoted by the same reference numerals.

[0027] (Embodiment) [1. Arrangement example of display device 100] FIG. 1 is a diagram showing an arrangement example of a plurality of display devices 100 according to an embodiment. In the present embodiment, the display device 100 is attached to each of a plurality of seats 2 arranged in the passenger cabin of the aircraft 1. That is, the display device 100 is attached to the rear side of the backrest of the seat 2. The display device 100 attached to the seat 2 is directed toward the rear seat, which is another seat 2 immediately behind that seat 2, and is visible to the passenger sitting on the rear seat. Such a display device 100 is used by the passenger on the rear seat. The display device 100 may be removable from and attachable to the seat 2 by the passenger. For example, a passenger sitting on a certain seat 2 may remove the display device 100 arranged in front and operate it by hand.

[0028] [2. Configuration overview of display device 100] FIG. 2 is a perspective view showing the appearance of the display device 100 according to the embodiment. FIG. 3 is an exploded perspective view of the display device 100 according to the embodiment. In the present embodiment, as shown in FIGS. 2 and 3, the direction in which the display device 100 displays an image is described as the minus Y-axis direction, the left-right direction as the X-axis direction, and the up-down direction as the Z-axis direction. That is, hereinafter, for example, when referring to "front", it means the minus Y-axis direction, and when referring to "rear", it means the plus Y-axis direction. There is no particular limitation on the posture of the display device 100 during use, and the display device 100 may be installed at a predetermined location so as to display an image downward, obliquely downward, upward, or obliquely upward.

[0029] As shown in FIGS. 2 and 3, the display device 100 according to the present embodiment includes a first panel 110, a second panel 120, a housing 150, and a shielding member 200. In the present embodiment, the first panel 110 is a touch panel having light transmissivity, and the second panel 120 is a display panel that displays an image. The first panel 110 has a first front surface 114 facing forward and a first back surface 115 facing rearward. The second panel 120 has a second front surface 124 facing forward and a second back surface 125 facing rearward.

[0030] As shown in FIG. 2, the first panel 110 includes a front panel 111 that forms a first front surface 114 of the first panel 110, a sensor panel 112 that detects contact of a human finger by a predetermined method such as a capacitance method, and an adhesive member 119 that adheres the front panel 111 and the sensor panel 112. The front panel 111, the sensor panel 112, and the adhesive member 119 have a predetermined light transmissibility. Thereby, a person located in front of the display device 100 can visually recognize an image displayed on the second panel 120 disposed to face the first back surface 115 of the first panel 110 through the first panel 110. In the present embodiment, the front panel 111 is a plate-like member formed of a transparent resin such as an acrylic resin. The adhesive member 119 is a transparent adhesive called, for example, OCA (Optical Clear Adhesive). The sensor panel 112 is a member in which a plurality of electrodes and the like for detecting a touched position are disposed on a base material formed of, for example, resin.

[0031] The detection result of the first panel 110, which is a touch panel, is sent via a wire (not shown) to a control circuit (not shown) that controls the image display of the second panel 120, which is a display panel. The control circuit can control the display of the image on the second panel 120 according to the detection result.

[0032] In the present embodiment, as the second panel 120, which is a display panel, for example, an organic EL display panel is adopted. In the present embodiment, the second front surface 124 of the second panel 120 is adhered to the first back surface 115 of the first panel 110 by an adhesive member 140. The adhesive member 140 is, like the adhesive member 119, for example, OCA (Optical Clear Adhesive). A more specific configuration of the second panel 120 will be described later with reference to FIG. 4.

[0033] As described above, when the first panel 110 and the second panel 120 bonded by the bonding member 140 are viewed from the negative Y-axis direction (hereinafter also referred to as "front view"), the size of the first panel 110 is larger than that of the second panel 120. That is, in the front view, the peripheral edge 110a of the first panel 110 protrudes from the second panel 120. By attaching this peripheral edge 110a to the side wall portion 151 of the housing 150, the first panel 110 and the second panel 120 are attached to the housing 150. The attachment mode of the peripheral edge 110a to the side wall portion 151 will be described later with reference to FIG. 4.

[0034] The housing 150 is a member that holds the first panel 110 and the second panel 120, and is manufactured, for example, by resin molding. The housing 150 includes an opposing wall portion 153 that opposes the second back surface 125 of the second panel 120, and a side wall portion 151 that protrudes forward from the periphery of the opposing wall portion 153. In the present embodiment, two attachment portions 155 are provided on the opposing wall portion 153 of the housing 150. As shown in FIG. 3, the two attachment portions 155 are spaced apart in the left-right direction. Each of the two attachment portions 155 has an attachment hole 155a. For example, a shaft body (such as a bolt) that connects the sheet 2 (see FIG. 1) or a fixing member interposed between the sheet 2 and the housing 150 and the housing 150 is inserted into each of the two attachment holes 155a. Thereby, the display device 100 is attached to the sheet 2 directly or via the fixing member. Note that at least a part of the second back surface 125 of the second panel 120 may be connected to the opposing wall portion 153 of the housing 150 by an adhesive or the like. The material of the housing 150 is not limited to resin, and the housing 150 may be formed of a metal such as aluminum or an aluminum alloy.

[0035] In the display device 100 configured as described above, a shielding member 200 extending rearward is disposed at the peripheral edge of the first panel 110. Thereby, when the second panel 120, which is the display panel, is damaged by an excessive impact, glass pieces generated by the damage are suppressed from flowing out through the gap between the peripheral edge 110a of the first panel 110 and the housing 150. Hereinafter, the shielding member 200 and the configuration around it in the display device 100 will be further described with reference to FIGS. 4 to 6.

[0036] In addition, when the base material of the sensor panel 112 is formed of glass as described later, in addition to the damage of the second panel 120, glass pieces generated by the damage of the sensor panel 112 are also suppressed from being released through the gap between the peripheral edge 110a of the first panel 110 and the housing 150 (not shown).

[0037] [3. Configuration of the shielding member 200 and its surroundings] FIG. 4 is a cross-sectional view showing the shielding member 200 and the configuration around it in the display device 100 according to the embodiment. In FIG. 4, a part of the cross-section of the display device 100, which is a part of the cross-section parallel to the YZ plane passing through the line IV-IV in FIG. 2, is schematically shown. FIG. 5 is a diagram schematically showing an example of a state where the display device 100 according to the embodiment has received an excessive impact. FIG. 6 is a cross-sectional view schematically showing a state where a part of the peripheral edge 110a of the first panel 110 according to the embodiment has come off from the housing 150. The position of the cross-section in FIG. 6 is in accordance with the position of the cross-section in FIG. 4. In FIGS. 4 and 6, for the sake of simplicity of illustration, the first panel 110 is shown as a single structure integrally including the front panel 111, the adhesive member 119, and the sensor panel 112.

[0038] As shown in FIG. 4, in the present embodiment, the second panel 120, which is an organic EL display panel, includes a glass substrate 121 and an organic EL element 126. More specifically, the second panel 120 includes a pair of glass substrates 121 facing each other in the front-rear direction, and an organic EL element 126 disposed between the pair of glass substrates 121. When distinguishing between the pair of glass substrates 121, the front glass substrate 121 is referred to as the glass substrate 121a, and the rear glass substrate 121 is referred to as the glass substrate 121b. The glass substrate 121a is a CF substrate, which is a glass substrate on which a color filter is formed, for example. The glass substrate 121b is a TFT substrate, which is a glass substrate on which various elements such as gate electrodes are laminated, for example. The organic EL element 126 is a light-emitting portion including an anode as a lower electrode, an EL layer as a light-emitting layer made of an organic material, and a cathode as a transparent upper electrode.

[0039] In the present embodiment, the second front surface 124 of the second panel 120 is formed by the front surface of the glass substrate 121a, and the second back surface 125 of the second panel 120 is formed by the back surface of the glass substrate 121b. Note that an optical member such as a polarizing plate may be disposed on the second front surface 124 of the second panel 120. Also, a heat dissipation member made of a metal foil such as a copper foil may be disposed on the second back surface 125 of the second panel 120. In the present embodiment, illustration and description of these optical member and heat dissipation member are omitted.

[0040] As shown in FIG. 4, the peripheral portion 110a of the first panel 110 is supported by the side wall portion 151 of the housing 150. Specifically, the side wall portion 151 has a support surface 151a facing forward, and the support surface 151a and the first back surface 115 at the peripheral portion 110a of the first panel 110 are connected by an adhesive member 145 such as double-sided tape or an adhesive. More specifically, in the present embodiment, as shown in FIG. 3, the side wall portion 151 is arranged in a rectangular ring shape in a front view. The entire (or almost entire) area of the peripheral portion 110a of the first panel 110 and the rectangular ring-shaped side wall portion 151 are connected via the adhesive member 145. That is, the entire (or almost entire) area of the peripheral portion 110a of the first panel 110 is supported by the housing 150. In the present embodiment, since the second panel 120 is attached to the first back surface of the first panel 110 via the adhesive member 145, the housing 150 supports the second panel 120 together with the first panel 110.

[0041] In the display device 100 configured as described above, the base materials of the front panel 111 and the sensor panel 112 of the first panel 110 are formed of resin. Therefore, for example, when an excessive impact is applied to the first panel 110 due to an object colliding from the front, the first panel 110 deforms as shown in FIGS. 5 and 6, for example.

[0042] Specifically, for example, when the display device 100 is attached to the back of the seat 2 (see FIG. 1) of the aircraft 1, the display device 100 is located in front of a passenger sitting on the seat 2 behind the seat 2. In this state, when the aircraft 1 shakes greatly or decelerates suddenly, etc., the head 500 of the passenger may collide with the display device 100. More specifically, for example, it is estimated that the head 500 collides with a position that is the central part in the left - right direction of the display device 100 and is closer to the upper end than the center in the up - down direction. In this case, the first panel 110 mainly formed of resin is deformed such that the portion where the head 500 collides is recessed backward, as schematically shown in FIG. 5. As a result, the peripheral edge portion 110a at the upper end and the central part of the first panel 110 is deformed so as to protrude forward from the side wall portion 151 of the housing 150. More specifically, when the portion where the head 500 collides is deformed so as to be recessed backward, the portion around the recess is deformed so as to be displaced forward with respect to the center of the recess. As a result, at the upper end and the central part of the first panel 110, the portion peeled off from the side wall portion 151 of the housing 150 tends to be deformed so as to protrude forward. At this time, since the portions on both the left and right sides of the peeled - off portion of the first panel 110 remain adhered to the side wall portion 151, strain concentrates on the peeled - off portion. As a result, as shown in FIG. 5, the peeled - off portion of the first panel 110 protrudes in a mountain - shape with the central part Fc in the left - right direction as the apex.

[0043] That is, although the peripheral edge portion 110a of the first panel 110 is adhered to the support surface 151a of the side wall portion 151 by the adhesive member 145 as described above, a force exceeding the adhesive force acts on the peripheral edge portion 110a, and as a result, the peripheral edge portion 110a is peeled off from the support surface 151a. That is, as shown in FIGS. 5 and 6, a gap is generated between the peripheral edge portion 110a at the upper end and the central part of the first panel 110 and the housing 150 (more specifically, the side wall portion 151 of the housing 150).

[0044] When the first panel 110 is deformed by such an excessive impact, the second panel 120 behind the first panel 110 is damaged directly by the first panel 110 colliding from the front. Specifically, for example, as schematically shown in FIG. 6, at least a part of the glass substrate 121 provided in the second panel 120 is broken, and as a result, a plurality of glass pieces, which are glass fragments, are scattered. Since the plurality of glass pieces include glass pieces having a size of about several millimeters and 1 mm or less, there is a possibility that these glass pieces flow out to the outside through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150. When such fine glass pieces flow out from the display device 100, the fine glass pieces can be a factor leading to further deterioration of the situation.

[0045] Note that, as shown in FIGS. 3 and 4, an adhesive member 140 is attached to the second front surface 124 of the second panel 120 which is a display panel. Therefore, when the front glass substrate 121a of the pair of glass substrates 121 is damaged by an impact, the adhesive member 140 may suppress the scattering of the glass pieces. However, as shown in FIG. 4, the adhesive member 140 does not reach up to the upper edge of the glass substrate 121a, and there is no member covering the upper surface of the glass substrate 121a. Therefore, it is difficult to suppress at least the glass pieces from the upper end portion (including the upper surface) of the glass substrate 121a by the adhesive member 140.

[0046] Also, a metal foil such as a copper foil can be disposed on the second back surface 125 of the second panel 120 as described above. In this case, when the rear glass substrate 121b of the pair of glass substrates 121 is damaged by an impact, the metal foil may suppress the scattering of the glass pieces. However, the metal foil does not cover up to the upper surface of the glass substrate 121b. Therefore, it is difficult to suppress at least the glass pieces from the upper surface of the glass substrate 121b by the metal foil.

[0047] Thus, when an excessive impact is applied to the second panel 120 including one or more glass substrates 121, fine glass pieces may scatter, and there is a risk that the scattered glass pieces may flow out to the outside through the gap between the peripheral edge portion 110a and the housing 150. Therefore, in the display device 100 according to the present embodiment, as shown in FIGS. 4 and 6, a shielding member 200 extending rearward is disposed at the peripheral edge portion 110a of the first panel 110. That is, one end 201 (more specifically, the front end 201) of the shielding member 200 is connected to the peripheral edge portion 110a of the first panel 110. The shielding member 200 suppresses the outflow of glass pieces to the outside through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150.

[0048] Note that the base material of the sensor panel 112 may be formed of glass. In this case, the shielding member 200 is preferably connected to the front panel 111.

[0049] That is, the technical features of the display device 100 according to the present embodiment are described as follows, for example. Note that the position, state, etc. of each element in the following description mean the position, state, etc. during normal use of the display device 100. That is, when an object collides with the display device 100, the position, state, etc. in the following description may not apply.

[0050] The display device 100 according to the present embodiment is a display device used in the aircraft 1. The display device 100 includes a first panel 110 having light transmissivity, a second panel 120 facing the first back surface 115 which is the back surface of the first panel 110, a housing 150, and a shielding member 200. The second panel 120 displays an image on the front surface (second front surface 124) and includes a glass substrate 121. The housing 150 forms a housing space 158 for housing the second panel 120 and has a side wall portion 151 that supports the peripheral edge portion 110a of the first panel 110. The shielding member 200 has one end 201 connected to the peripheral edge portion 110a of the first panel 110. The shielding member 200 has a portion extending rearward from the peripheral edge portion 110a inside the housing space 158.

[0051] According to the display device 100 configured as described above, even if, for example, due to an excessive impact, the glass substrate 121 of the second panel 120 is cracked and the peripheral portion 110a of the first panel 110 comes off the housing 150, a shielding member 200 having a portion extending rearward is disposed at the peripheral portion 110a of the first panel 110. Therefore, it is possible to suppress glass pieces from flowing out to the outside of the housing 150 through the gap between the peripheral portion 110a of the first panel 110 and the housing 150. Accordingly, the display device 100 according to the present embodiment is a display device with improved safety.

[0052] Specifically, in the present embodiment, as the shielding member 200, a sheet-like or film-like member formed of a resin such as polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), or polystyrene (PS) is adopted. Therefore, the shielding member 200 has relatively high flexibility. Also, there is no particular limitation on the method of connecting one end 201 of the shielding member 200 to the first panel 110. For example, one end 201 of the shielding member 200 is adhered to the peripheral portion 110a on the first back surface 115 of the first panel 110 by an adhesive or a double-sided tape. Note that the shielding member 200 according to the present embodiment is not electrically connected to the first panel 110, but it is also possible to adopt a member electrically connected to the first panel 110 as the shielding member. A configuration in which a member electrically connected to the first panel 110 is adopted as the shielding member will be described later as a modification example 2 of the embodiment.

[0053] In the present embodiment, more specifically, one end 201 of the shielding member 200 is connected to the peripheral portion 110a of the first panel 110 in a predetermined direction orthogonal to the front-rear direction, and the shielding member 200 has a portion located on the side of the second panel 120 in the predetermined direction. For example, in FIG. 4, one end 201 of the shielding member 200 is connected to the peripheral portion 110a at the upper end portion of the first panel 110, and the shielding member 200 has a portion located above the second panel 120.

[0054] More specifically, in the present embodiment, the other end 202 of the shielding member 200 is located behind the second back surface 125 which is the back surface of the second panel 120.

[0055] In this way, in the present embodiment, the length of the shielding member 200 in the front-rear direction is relatively large. Therefore, when the peripheral edge portion 110a of the first panel 110 comes off the housing 150, the outflow of glass pieces through the gap between the peripheral edge portion 110a and the housing 150 is more reliably suppressed.

[0056] The position of the other end 202 of the shielding member 200 in the present embodiment is described as follows, for example. The housing 150 has an opposing wall portion 153 that faces the second back surface 125. The other end 202 of the shielding member 200 is located between the second back surface 125 and the opposing wall portion 153.

[0057] In this way, in the present embodiment, the shielding member 200 is formed to have a size that reaches from the peripheral edge portion 110a of the first panel 110 to the back surface (second back surface 125) of the second panel 120. Therefore, the effect of suppressing the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 is further improved. That is, even when the width of the gap in the front-rear direction becomes relatively large, since the length of the shielding member 200 extending from the first panel 110 is relatively long, the gap is highly likely to be covered by the shielding member 200 in the front-rear direction.

[0058] In the present embodiment, as shown in FIGS. 3, 4, and 6, the shielding member 200 is disposed at the peripheral edge portion 110a at the upper end portion of the first panel 110.

[0059] In this embodiment, the first panel 110 has a horizontally long rectangular shape. Therefore, it is considered that the upper and lower end portions of the first panel 110 are portions that are likely to come off from the housing 150. Thus, as in the display device 100 according to this embodiment, by disposing the shielding member 200 at the peripheral edge portion 110a at the upper end of the first panel 110, the effectiveness of the effect of suppressing the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 is improved. In particular, as shown in FIG. 5, when there is a high possibility that an external object will collide with a position closer to the upper end than the center in the vertical direction of the first panel 110, it is useful to dispose the shielding member 200 at the peripheral edge portion 110a at the upper end of the first panel 110.

[0060] For the same reason, for example, when there is a high possibility that an external object will collide with a position closer to the lower end than the center in the vertical direction of the first panel 110, the shielding member 200 may be disposed at the peripheral edge portion 110a at the lower end of the first panel 110. Thereby, the effectiveness of the effect of suppressing the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 is improved.

[0061] In this embodiment, the arrangement range of the shielding member 200 in the left-right direction will be described as follows, for example. That is, in the display device 100 according to the embodiment, the housing 150 has two attachment portions 155 which are portions where other objects arranged behind the housing 150 can be attached (see FIG. 3). The two attachment portions 155 are arranged at intervals in the left-right direction. The arrangement range of the shielding member 200 in the left-right direction includes the range between the two attachment portions 155 in the left-right direction. For example, as shown in FIG. 3, assume a case where in the left-right direction (X-axis direction), the position of the left attachment portion 155 is P1 and the position of the right attachment portion 155 is P2. Note that the position of the attachment portion 155 is defined, for example, based on the center of the attachment hole 155a that the attachment portion 155 has. Further, when the range between P1 and P2 in the left-right direction is defined as range Ab, the arrangement range Aa of the shielding member 200 in the left-right direction includes at least range Ab.

[0062] In the present embodiment, the attachment portion 155 is attached to the sheet 2 (see FIG. 1) or a fixing member fixed to the sheet 2 as described above. Therefore, the two attachment portions 155 are two fixing points in the display device 100. Looking at the display device 100 as a whole, it can be said that the range Ab between the two attachment portions 155 is a portion that is likely to be deformed rearward by an external force from the front. Therefore, when an object collides with any of the ranges Ab in the left - right direction from the front of the display device 100 (for example, see FIG. 5), the probability that the deformation of the first panel 110 in the range Ab becomes large is high. As a result, the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 in the range Ab may become large. In this regard, according to the display device 100 according to the present embodiment, the shielding member 200 is disposed in a range where the first panel 110 is likely to be deformed by an external force received from the front. Specifically, the arrangement range Aa of the shielding member 200 in the left - right direction includes the range Ab between the two attachment portions 155. Therefore, the effectiveness of the effect of the shielding member 200, that is, the effect of suppressing the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 is improved.

[0063] Also, the length of the shielding member 200 in the left - right direction according to the present embodiment is described as follows. That is, in the display device 100 according to the present embodiment, the shielding member 200 is disposed in a range including the center C (see FIG. 3) of the housing 150 in the left - right direction and over a range of not less than 1 / 3 and not more than 1 / 2 of the length W (see FIG. 3) of the housing 150 in the left - right direction. In the present embodiment, the position of the center C of the housing 150 in the left - right direction coincides with the center position of the first panel 110 in the left - right direction and the center position of the second panel 120 in the left - right direction.

[0064] As described above, in the present embodiment, the shielding member 200 is disposed in a range centered on the central portion of the first panel 110 that is easily detached from the housing 150. Therefore, the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 is more efficiently suppressed. More specifically, from the viewpoint of more surely suppressing the outflow of glass pieces through the gap between the peripheral edge portion 110a and the housing 150, it is conceivable to make the length of the shielding member 200 in the left-right direction substantially the same as the total length of the housing 150 in the left-right direction. That is, it is conceivable to dispose the shielding member 200 having the same length as the total length of the upper end portion of the first panel 110 in the left-right direction, for example, at the upper end portion of the first panel 110. However, in this case, for example, it becomes difficult to accurately adhere the shielding member 200 to the first panel 110. In addition, the operation of attaching the first panel 110 with the shielding member 200 attached to the housing 150 becomes complicated. Furthermore, there may also be a problem of an increase in the manufacturing cost of the shielding member 200. Regarding these points, in the present embodiment, the length of the shielding member 200 in the left-right direction is set to be not less than 1 / 3 and not more than 1 / 2 of the length W of the housing 150 in the left-right direction. Furthermore, the arrangement range Aa of the shielding member 200 in the left-right direction is a range including the center C in the left-right direction of the housing 150. Thereby, both the suppression of the outflow of glass pieces through the gap between the peripheral edge portion 110a of the first panel 110 and the housing 150 and the suppression of the increase in the difficulty regarding the assembly (manufacture) of the display device 100 are achieved.

[0065] In the present embodiment, the other end 202 of the shielding member 200 is a free end. That is, while one end 201 of the shielding member 200 is connected to the peripheral edge portion 110a of the first panel 110, the other end 202, which is the end opposite to the one end 201 of the shielding member 200, is not fixed to any member included in the display device 100.

[0066] As described above, since the shielding member 200 only needs to be connected to the peripheral edge portion 110a of the first panel 110, the assembly of the display device 100 including the shielding member 200 is easy.

[0067] Incidentally, the other end 202 of the shielding member 200 may be fixed to the second back surface 125 (see FIG. 4) of the second panel 120 by an adhesive or the like. Thereby, the posture of the shielding member 200 is stabilized. Therefore, for example, the operation for attaching the first panel 110 in a state where the second panel 120 and the shielding member 200 are attached to the housing 150 is facilitated.

[0068] When the other end 202 of the shielding member 200 is fixed to the second panel 120 as described above, it is preferable that the fixing force between the one end 201 of the shielding member 200 and the first panel 110 is stronger than the fixing force between the other end 202 and the second panel 120. That is, when the peripheral edge portion 110a of the first panel 110 is peeled off from the side wall portion 151 of the housing 150 (see FIGS. 5 and 6), the one end 201 of the shielding member 200 preferably moves forward following the peripheral edge portion 110a from the viewpoint of closing the gap through which the glass pieces can flow out with the shielding member 200. Therefore, when the length of the shielding member 200 extending from the peripheral edge portion 110a is relatively short and the peripheral edge portion 110a moves forward, it is preferable that the other end 202 of the two fixing portions (one end 201 and the other end 202) of the shielding member 200 is released from the fixing first. This also applies when the other end 202 of the shielding member 200 is fixed to the housing 150 with an adhesive or the like.

[0069] As described above, the display device 100 according to the present embodiment has been described. However, the configuration of the display device 100 is not limited to the configuration described in the above embodiment. Therefore, a modification example of the configuration of the display device 100 will be described centering on the differences from the above embodiment.

[0070] [4-1. Modification Example 1] FIG. 7 is a cross-sectional view showing the shielding member 200a of the display device 100a according to Modification Example 1 of the embodiment and the configuration around it. The position of the cross section in FIG. 7 is in accordance with the position of the cross section in FIG. 4.

[0071] As shown in FIG. 7, the shielding member 200a according to this modification has one end 201a connected to the peripheral edge 110a of the first panel 110 and has a portion extending rearward from the peripheral edge 110a inside the accommodation space 158. Further, the other end 202a of the shielding member 200a is located rearward of the second rear surface 125 which is the rear surface of the second panel 120. In these respects, the shielding member 200a according to this modification is common to the shielding member 200 according to the embodiment.

[0072] The shielding member 200a according to this modification is composed of two members, which is different from the shielding member 200 according to the embodiment in this regard. Specifically, the shielding member 200a according to this modification has a buffer member 204 which is a portion extending rearward from the peripheral edge 110a, and a plate-like member 205 which is connected to the buffer member 204 and has the other end 202a. In this modification, the buffer member 204 is, for example, a sponge formed of polyurethane foam or the like. The plate-like member 205 is, for example, a sheet-like or film-like member formed of a resin such as PET or PP, similar to the shielding member 200 according to the embodiment.

[0073] Thus, in this modification, the portion of the shielding member 200a connected to the peripheral edge 110a of the first panel 110 is the buffer member 204 realized by a sponge or the like. Therefore, when the first panel 110 is deformed as shown in FIG. 5 due to an excessive impact, the buffer member 204 easily follows the deformation. Accordingly, for example, problems such as the shielding member 200a coming off from the peripheral edge 110a due to the deformation are less likely to occur. That is, the effect of suppressing the outflow of glass pieces by the shielding member 200a is more surely achieved. Further, the relatively thin plate-like member 205 is provided as a member forming the other end 202a of the shielding member 200a. Therefore, the portion of the shielding member 200a including the other end 202a can be easily arranged in the narrow space between the second rear surface 125 of the second panel 120 and the opposing wall portion 153 of the housing 150.

[0074] [4-2. Modification 2] FIG. 8 is a cross-sectional view showing a shielding member 200b of the display device 100b according to Modification 2 of the embodiment and the configuration around it. The position of the cross-section in FIG. 8 is in accordance with the position of the cross-section in FIG. 4.

[0075] As shown in FIG. 8, the shielding member 200b according to this modification has one end 201b connected to the peripheral edge 110a of the first panel 110 and has a portion extending rearward from the peripheral edge 110a inside the accommodation space 158. In this regard, the shielding member 200b according to this modification is common to the shielding member 200 according to the embodiment.

[0076] The shielding member 200b according to this modification includes an electric wire electrically connected to the first panel 110 and is realized by a wiring member 300 with high flexibility, which is different from the shielding member 200 according to the embodiment in this respect. The wiring member 300 is, for example, a member called a flexible printed circuit (FPC) and has a configuration in which an electric wire is sandwiched between thin insulating materials.

[0077] The wiring member 300 is electrically connected to, for example, the sensor panel 112 (see FIG. 3) provided in the first panel 110. The sensor panel 112 can exchange information (electrical signals) with a control circuit (not shown) that controls the image display of the second panel 120 via the wiring member 300.

[0078] Thus, in the display device 100b including the first panel 110 which is a touch panel, the wiring member 300 including an electric wire electrically connected to the first panel 110 is used as the shielding member 200b. Thereby, the configuration of the display device 100b provided with the shielding member 200b that can suppress the outflow of glass pieces is simplified.

[0079] [4-3. Modification 3] FIG. 9 is a cross-sectional view showing a shielding member 200c of the display device 100c according to Modification 3 of the embodiment and the configuration around it. The position of the cross-section in FIG. 9 is in accordance with the position of the cross-section in FIG. 4.

[0080] As shown in FIG. 9, the shielding member 200c according to this modification has one end 201c connected to the peripheral edge portion 110a of the first panel 110, and has a portion extending rearward from the peripheral edge portion 110a inside the accommodation space 158. In this regard, the shielding member 200c according to this modification is common to the shielding member 200 according to the embodiment. That is, one end 201c of the shielding member 200c according to this modification is connected to the peripheral edge portion 110a of the first panel 110 in a predetermined direction (upward in FIG. 9) orthogonal to the front-rear direction. Further, the shielding member 200c has a portion located on the side of the second panel 120 in the predetermined direction.

[0081] In the front-rear direction, the other end 202c of the shielding member 200c according to this modification is located in front of the second rear surface 125 which is the rear surface of the second panel 120, which is different from the shielding member 200 according to the embodiment in this regard. That is, the shielding member 200c according to this modification has a shorter length D in the direction extending from the peripheral edge portion 110a compared to the shielding member 200 according to the embodiment.

[0082] Thus, even when the length D of the shielding member 200c is relatively short, for example, if the distance of the gap between the peripheral edge portion 110a and the housing 150 formed due to a collision of an object or the like is shorter than D, the shielding member 200c can block the gap in the front-rear direction. Also, even if the gap between the peripheral edge portion 110a and the housing 150 becomes large to the extent that the other end 202c of the shielding member 200c is exposed to the outside (that is, when the distance of the gap > D), the outflow of glass pieces to the outside from the gap is suppressed by the shielding member 200c erected on the peripheral edge portion 110a on the first rear surface 115.

[0083] (Other Embodiments) As described above, the display device according to the present disclosure has been described based on the above-described embodiment and its modifications. However, the present disclosure is not limited to the above-described embodiment and modifications.

[0084] The second panel 120, which is a display panel, may be a type of display panel different from the organic EL display panel. For example, a liquid crystal display panel may be adopted as the second panel 120. The liquid crystal display panel includes a pair of glass substrates with transparent electrodes sandwiching a liquid crystal layer. Therefore, when the liquid crystal display panel is subjected to an excessive impact, the glass substrate with the transparent electrode may be damaged, and as a result, minute glass pieces may be generated. Accordingly, the structure capable of suppressing the outflow of glass pieces to the outside provided in the display device 100 according to the above embodiment is useful even when the second panel 120 is a liquid crystal display panel.

[0085] The shielding member 200 does not necessarily have to be a sheet-like or film-like member formed of a resin such as PET or PP. For example, a sponge forming the buffer member 204 provided in the shielding member 200a according to the above Modification 1, which has a thickness such that it is not generally recognized as being sheet-like or film-like, may be adopted as the shielding member. That is, the shielding member 200a according to the above Modification 1 may be composed only of the buffer member 204.

[0086] The arrangement position of the shielding member 200 is not limited to the arrangement position shown in FIGS. 3 and 4 and the like. As described above, the shielding member 200 may be arranged at the peripheral edge portion 110a at the lower end portion of the first panel 110. The shielding member 200 may be arranged at the peripheral edge portion 110a at the left end portion or the right end portion of the first panel 110. Further, the shielding member 200 may be arranged over the entire or substantially the entire peripheral edge portion 110a of the first panel 110. That is, the arrangement position of the shielding member 200 may be appropriately determined, for example, based on a position in the display device 100 where other objects are likely to collide.

[0087] In the above-described embodiment, the side wall portion 151 of the housing 150 is adhered to the first back surface 115 at the peripheral portion 110a of the first panel 110 by the adhesive member 145. However, the end surface of the peripheral portion 110a (for example, the end surface in the +Z-axis direction in FIG. 4) and the side wall portion 151 may be adhered. Further, when the side wall portion 151 includes a frame portion disposed in front of the peripheral portion 110a, the frame portion may be connected to the first front surface 114 of the peripheral portion 110a by the adhesive member 145 or the like. In any case, in order to meet the requirement of, for example, a narrow bezel, it is necessary to relatively reduce the adhesion area between the peripheral portion 110a and the side wall portion 151 of the housing 150. Therefore, when an excessive impact is applied to the first panel 110, the glass substrate 121 included in the second panel 120 may be damaged, and the peripheral portion 110a may come off from the side wall portion 151 of the housing 150 (see, for example, FIGS. 5 and 6). Therefore, even if the connection position of the peripheral portion 110a of the first panel 110 with the side wall portion 151 is a position other than the first back surface 115, the structure of suppressing the outflow of glass pieces to the outside by the shielding member 200 included in the display device 100 according to the above-described embodiment is useful.

[0088] The first panel 110 does not need to be a touch panel. The first panel 110 may be, for example, a light-transmitting panel for protecting the second panel 120, or may be an optical member that adds some optical effect to the image displayed by the second panel 120. That is, the first panel 110 is a member formed of a material such as resin that is more difficult to break than glass, and even if it breaks, it is difficult to scatter and is unlikely to become sharp fragments, and it only needs to be a member having a transparency that allows the image displayed by the second panel 120 to be visible, and the function of the first panel 110 is not particularly limited.

[0089] The size and shape of the display device 100 are not limited to, for example, the size and shape shown in FIGS. 1 and 2. The display device 100 may have, for example, a size and shape that can be held by a user with one hand. In this case, the display device 100 may incorporate a processor, a memory, a battery, etc. for executing various processes such as image display and communication with other devices. That is, the display device 100 may be realized as a portable terminal.

[0090] Each of the various supplementary matters regarding the display device 100 according to the above embodiment may be appropriately applied to each of Modifications 1 to 3 of the embodiment. In addition, forms obtained by making various modifications conceivable by those skilled in the art to each embodiment and modification, and forms realized by arbitrarily combining the components and functions in each embodiment and modification without departing from the gist of the present invention are also included in the present invention. Also, combinations of two or more claims arbitrarily selected from the plurality of claims described in the claims at the time of filing of the present application without technical contradiction are also included in the present invention.
