[0008] Hereinafter, embodiments of a display device according to the present disclosure will be described with reference to the drawings.
[0009] (Embodiment) The display device according to the embodiment is configured by fitting a frame to a display, and is devised to properly position the display relative to the frame.
[0010] A display system 3 including a display device 1 according to the embodiment can be mounted on a vehicle 5, as shown in FIG. 1. For example, the display device 1 is an electronic mirror, and the display system 3 is an electronic mirror system. FIG. 1 is a diagram showing a vehicle 5 on which the display system 3 is mounted. The display system 3 includes the display device 1 and an imaging device 2.
[0011] The imaging device 2 is an on-board camera mounted on the vehicle 5, and is installed on the outside or inside of the vehicle body 6. The imaging device 2 may be installed at the rear end of the vehicle body 6 to image the rear, at the end of the vehicle body 6 near the door to image the side, or at the front end of the vehicle body 6 to image the front.
[0012] The display device 1 is disposed inside the vehicle interior 7. The display device 1 is, for example, an electronic mirror, has a surface 1a, and is capable of displaying an image captured by the imaging device 2 on the surface 1a. The display device 1 is configured to be switchable between a display mode and a mirror mode. The display mode is a mode in which the display panel of the display device 1 displays an image captured by the imaging device 2, and the display device 1 functions as a display. The mirror mode is a mode in which the display panel of the display device 1 is turned off, and the display device 1 functions as a mirror.
[0013] When the display device 1 is an electronic mirror for rearview visibility, it may be implemented in the form of a rearview mirror, with the surface 1a facing the vehicle interior 7 and the shape of the surface 1a being the mirror surface of a rearview mirror. When the display device 1 is an electronic mirror for side visibility, it may be implemented in the form of a door mirror (for example, door mirror 61), with the surface 1a facing the rear of the vehicle body 6 and the shape of the surface 2a being the mirror surface of a door mirror. When the display device 1 is an electronic mirror for forward visibility, it may be implemented in the form of an in-vehicle display device (for example, display device 71), with the surface 1a facing the vehicle interior 7 and the shape of the display unit of the display device.
[0014] FIG. 1 illustrates a configuration in which the imaging device 2 is installed at the rear end 6a of a vehicle body 6, and the display device 1 is applied to an electronic mirror system for rearward visibility. The electronic mirror system for rearward visibility is also called an electronic rearview mirror. The imaging device 2 captures an image of the area behind the vehicle body. The display device 1 can display the image of the area behind the vehicle body captured by the imaging device 2.
[0015] When the display device 1 is an electronic mirror for rearview, it may be configured as shown in Figures 2 and 3. Figure 2 is a front view showing the external configuration of the display device 1. Figure 3 is an exploded perspective view showing the configuration of the display device 1. In the following, the longitudinal direction of the display device 1 is defined as the Y direction, the direction perpendicular to the surface 1a is defined as the Z direction, and the direction perpendicular to the Y direction and the Z direction is defined as the X direction.
[0016] The display device 1 has a frame (second frame) 11, a display 12, and a housing 13.
[0017] The frame 11 is disposed on the -Z side of the display 12 and the housing 13. The frame 11 extends in a frame shape in the XY directions. The frame 11 has an opening 11e on the inside. The frame 11 has a shape that corresponds to the outer contour of the display 12. The frame 11 is configured so that it can be fitted into the display 12 from the -Z side. The frame 11 may be a substantially rectangular frame with the Y direction as the longitudinal direction. The frame 11 may be a substantially rectangular frame with rounded corners. The frame 11 may be formed from a material whose main component is resin.
[0018] The frame 11 has inner surfaces 11a to 11d. Each of the inner surfaces 11a to 11d faces inward of the frame 11. The inner surface 11a is disposed on the +X side of the frame 11 and extends in the Y direction. The inner surface 11b is disposed on the -X side of the frame 11 and extends in the Y direction. The inner surface 11c is disposed on the -Y side of the frame 11 and extends in the X direction. The inner surface 11d is disposed on the +Y side of the frame 11 and extends in the X direction.
[0019] The display 12 is disposed on the +Z side of the frame 11 and on the -Z side of the housing 13. The display 12 extends in a plate shape in the X and Y directions. The display 12 may be in the shape of a substantially rectangular plate with the Y direction as the longitudinal direction. The display 12 may also be in the shape of a substantially rectangular frame with rounded corners.
[0020] The display 12 has a display main body 121, a light guide plate 122, a case 123, and a frame 124. The frame 124 forms end faces 12a to 12d and a rear face 12g of the display 12. The display main body 121 forms a front face 12f of the display 12. At least the portions of the frame (first frame) 124 near the end faces 12a to 12d may be made of a material containing metal as a main component.
[0021] End faces 12a to 12d correspond to inner faces 11a to 11d. End face 12a is disposed on the +X side of display 12 and extends along the Y direction. End face 12b is disposed on the -X side of display 12 and extends along the Y direction. End face 12c is disposed on the -Y side of display 12 and extends along the X direction. End face 12b is disposed on the +Y side of display 12 and extends along the X direction.
[0022] The front surface 12f is disposed on the −Z side of the display 12 and extends along the XY directions. The back surface 12g is disposed on the +Z side of the display 12 and extends along the XY directions.
[0023] The housing 13 is disposed on the +Z side of the frame 11 and the display 12. The housing 13 generally has a roughly box shape with the -Z side open. The housing 13 is configured to be able to fit into the frame 11 from the +Z side, and is configured to be able to house the display 12 from the +Z side. The housing 13 may be able to fit into the frame 11 in a state where the frame 11 is fitted into the display 12. The housing 13 may be roughly box-shaped with the Y direction as the longitudinal direction. The housing 13 may also be roughly box-shaped with rounded corners and an open -Z side.
[0024] The housing 13 has inner surfaces 13a to 13d.
[0025] Inner surfaces 13a to 13d correspond to inner surfaces 11a to 11d. Inner surface 13a is disposed on the +X side of housing 13 and extends along the Y direction. Inner surface 13b is disposed on the -X side of housing 13 and extends along the Y direction. Inner surface 13c is disposed on the -Y side of housing 13 and extends along the X direction. Inner surface 13b is disposed on the +Y side of housing 13 and extends along the X direction.
[0026] When the frame 11 is fitted to the frame 124 and the housing 13 is fitted to the frame 11, each end face 12a to 12d faces the corresponding inner face 11, the front face 12f is exposed on the -Z side, and the back face 12g is exposed on the +Z side. The outer edge portion of the front face 12f faces the frame 11, and its inner portion is exposed through the opening 11e. The back face 12g faces the housing 13. The frame 11 forms a part of the housing of the display device 1, and the housing 13 forms another part of the housing of the display device 1.
[0027] Next, the detailed configuration of the frame 11 and the display 12 will be described with reference to Figs. 4 to 6. Fig. 4 is a perspective view showing the configuration of the frame 11 and the display 12. Fig. 5 is a front view showing the configuration of the frame 11 and the display 12, illustrating a state in which the frame 11 is attached to the display 12. Fig. 6 is a front view showing the configuration of the display 12, illustrating a state in which the frame 11 is not attached.
[0028] The frame 124 has a protrusion 1241 and a protrusion 1244 on the end face 12a, and a protrusion 1242 and a protrusion 1245 on the end face 12b.
[0029] The protrusion 1241 is disposed on the +Y side of the center of the end face 12a and protrudes from the end face 12a to the -X side. The protrusion 1241 may be disposed on the +Z side of the center of the end face 12a at a position on the +Y side. The longitudinal direction of the protrusion 1241 is the Y direction. The protrusion 1241 may be substantially rectangular in a YZ plane view.
[0030] The protrusion 1244 is disposed on the -Y side of the center of the end face 12a and protrudes from the end face 12a to the -X side. The protrusion 1244 may be disposed on the +Z side of the center of the end face 12b at a position on the -Y side. The longitudinal direction of the protrusion 1244 is the Y direction. The protrusion 1244 may be substantially rectangular in YZ plane view.
[0031] The protrusion 1242 is disposed on the +Y side of the center of the end face 12b, and protrudes from the end face 12b to the +X side. The protrusion 1242 may be disposed on the +Z side of the center of the end face 12b at a position on the +Y side of the center. The Y direction is the longitudinal direction of the protrusion 1242. The protrusion 1242 may be substantially rectangular in a YZ plane view.
[0032] The protrusion 1245 is disposed on the -Y side of the center of the end face 12b and protrudes from the end face 12b to the +X side. The protrusion 1245 may be disposed on the +Z side of the center of the end face 12b at a position on the -Y side of the center. The Y direction is the longitudinal direction of the protrusion 1245. The protrusion 1245 may be substantially rectangular in a YZ plane view.
[0033] The frame 11 has a claw portion 111 and a claw portion 114 on an inner surface 11a, and has a claw portion 112, a contact member 113, a claw portion 115, and a contact member 116 on an inner surface 11b.
[0034] The claw portion 111 corresponds to the protrusion 1241 and is disposed at a position on the +Y side of the center on the inner surface 11a. The claw portion 111 extends in the Z direction on the inner surface 11a. The claw portion 111 extends on the inner surface 11a from the end on the -Z side to a Z position beyond the end on the +Z side. The claw portion 111 has an opening 1111 at a position corresponding to the protrusion 1241. The longitudinal direction of the opening 1111 is the Y direction. The opening 1111 may be substantially rectangular in a YZ plane view. This allows the claw portion 111 to fit into the protrusion 1241.
[0035] As shown in FIGS. 7 and 8, the claw portion 111 has a portion 111a, a portion 111b, and multiple portions 111c. FIGS. 7 and 8 are enlarged perspective views showing the configuration of the claw portion 111, and are enlarged perspective views of portion A in FIG. 5. The portion 111a is spaced apart from the portion 111b in the Z direction. The portion 111a is located on the tip side of the claw portion 111. The portion 111b is spaced apart from the portion 111a in the Z direction. The portion 111b is located on the base side of the claw portion 111. The multiple portions 111c include a portion 111c_1 arranged on the +Y side and a portion 111c_2 arranged on the -Y side. The multiple portions 111c are spaced apart from each other in the Y direction. Each of the multiple portions 111c is connected between the portion 111a and the portion 111b in the Z direction. The plurality of portions 111c each have a width in the Y direction that is narrower than the portions 111a and 111b. The plurality of portions 111c each have a thickness in the X direction that is thinner than the portion 111a. This allows the claw portion 111 to function as a member for preventing the display 12 from coming off and also as a leaf spring.
[0036] The claw portion 112 shown in Figures 4 and 5 corresponds to the protrusion 1242 and is arranged at a position on the +Y side of the center on the inner surface 11b. The claw portion 112 extends in the Z direction on the inner surface 11b. The claw portion 112 extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The claw portion 112 has an opening 1121 at a position corresponding to the protrusion 1242. The longitudinal direction of the opening 1121 is the Y direction. The opening 1121 may be approximately rectangular in a YZ plane view. This allows the claw portion 112 to fit into the protrusion 1242.
[0037] As shown in FIG. 9, the claw portion 112 has a portion 112a, a portion 112b, and a plurality of portions 112c. FIG. 9 is an enlarged perspective view showing the configuration of the claw portion 112 and the abutting member 113, respectively, and is an enlarged perspective view of portion B in FIG. 5. The portion 112a is spaced apart from the portion 112b in the Z direction. The portion 112a is located on the tip side of the claw portion 112. The portion 112b is spaced apart from the portion 112a in the Z direction. The portion 112b is located on the base side of the claw portion 112. The plurality of portions 112c include a portion 112c_1 arranged on the +Y side and a portion 112c_2 arranged on the -Y side. The plurality of portions 112c are spaced apart from one another in the Y direction. Each of the plurality of portions 112c is connected between the portion 112a and the portion 112b in the Z direction. The plurality of portions 112c each have a width in the Y direction that is narrower than the portions 112a and 112b. The plurality of portions 112c each have a thickness in the X direction that is equal to that of the portion 112a. This allows the claw portions 112 to function as members for preventing the display 12 from slipping out.
[0038] The abutment member 113 is disposed at a position on the +Y side of the center on the inner surface 11b. The abutment member 113 extends in the Z direction on the inner surface 11b. The abutment member 113 extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. This allows the abutment member 113 to abut against the inner surface 11b at a position on the inner surface 11b corresponding to the claw portion 111.
[0039] As shown in Fig. 9, the abutment member 113 has a portion 113a and a portion 113b. The portion 113a extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The portion 113b is connected to the portion 113a in the X direction and extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The width of the portion 113b in the Y direction is narrower than that of the portion 113a. This gives the abutment member 113 relatively high rigidity in the X direction, and the inner surface 11b can be used as a reference abutment surface.
[0040] 4 and 5 is disposed on the inner surface 11b at a position corresponding to the claw portion 111. The abutment member 113 is located within a Y-direction threshold distance Lth from an imaginary line VL1 that passes through the claw portion 111 and extends in the X-direction. The Y-direction distance L1 (see FIG. 5) between the abutment member 113 and the claw portion 111 is equal to or less than the Y-direction threshold distance Lth. The Y-direction threshold distance Lth can be experimentally determined in advance as a distance at which the claw portion 111 and the abutment member 113 can cooperate to position the display 12. The Y-direction threshold distance Lth may be, for example, 30 mm.
[0041] When the frame 11 is fitted into the frame 124, the portion 111a abuts against the end face 12a. The portion 111b is spaced apart from the end face 12a in the X direction. The portions 111c_1 and 111c_2 are each spaced apart from the end face 12a in the X direction. The portion 113a is spaced apart from the end face 12b in the X direction. The portion 113b abuts against the end face 12b.
[0042] The elastic modulus in the X direction of the claw portions 111 is greater than the elastic modulus in the X direction of the contact members 113, and is greater than the elastic modulus in the X direction of the claw portions 112. The rigidity in the X direction of the contact members 113 is greater than the rigidity in the X direction of the claw portions 111, and is greater than the rigidity in the X direction of the claw portions 112. This allows the contact members 113 to use the inner surface 11b as a reference contact surface, the claw portions 111 to function as leaf springs, and to urge the frame 124 toward the inner surface 11b, thereby positioning the display 12 in the X direction.
[0043] The claw portion 114 corresponds to the protrusion 1244 and is disposed at a position on the -Y side of the center on the inner surface 11a. The claw portion 114 extends in the Z direction on the inner surface 11a. The claw portion 114 extends on the inner surface 11a from the end on the -Z side to a Z position beyond the end on the +Z side. The claw portion 114 has an opening 1141 at a position corresponding to the protrusion 1244. The longitudinal direction of the opening 1141 is the Y direction. The opening 1141 may be substantially rectangular in a YZ plane view. This allows the claw portion 114 to fit into the protrusion 1244.
[0044] As shown in FIGS. 10 and 11, the claw portion 114 has a portion 114a, a portion 114b, and multiple portions 114c. FIGS. 10 and 11 are enlarged perspective views showing the configuration of the claw portion 114, and are enlarged perspective views of portion C in FIG. 5. The portion 114a is spaced apart from the portion 114b in the Z direction. The portion 114a is located on the tip side of the claw portion 114. The portion 114b is spaced apart from the portion 114a in the Z direction. The portion 114b is located on the base side of the claw portion 114. The multiple portions 114c include a portion 114c_1 arranged on the +Y side and a portion 114c_2 arranged on the -Y side. The multiple portions 114c are spaced apart from each other in the Y direction. Each of the multiple portions 114c is connected between the portion 114a and the portion 114b in the Z direction. The plurality of portions 114c each have a width in the Y direction that is narrower than the portions 114a and 114b. The plurality of portions 114c each have a thickness in the X direction that is thinner than the portion 114a. This allows the claw portion 114 to function as a member for preventing the display 12 from coming off and also as a leaf spring.
[0045] The claw portion 115 shown in Figures 4 and 5 corresponds to the protrusion 1245 and is arranged at a position on the -Y side of the center on the inner surface 11b. The claw portion 115 extends in the Z direction on the inner surface 11b. The claw portion 115 extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The claw portion 115 has an opening 1151 at a position corresponding to the protrusion 1245. The longitudinal direction of the opening 1151 is the Y direction. The opening 1151 may be approximately rectangular in a YZ plane view. This allows the claw portion 115 to fit into the protrusion 1245.
[0046] As shown in FIG. 12, the claw portion 115 has a portion 115a, a portion 115b, and a plurality of portions 115c. FIG. 12 is an enlarged perspective view showing the configuration of the claw portion 115 and the abutting member 116, respectively, and is an enlarged perspective view of portion D in FIG. 5. The portion 115a is spaced apart from the portion 115b in the Z direction. The portion 115a is located on the tip side of the claw portion 115. The portion 115b is spaced apart from the portion 115a in the Z direction. The portion 115b is located on the base side of the claw portion 115. The plurality of portions 115c include a portion 115c_1 disposed on the +Y side and a portion 115c_2 disposed on the -Y side. The plurality of portions 115c are spaced apart from one another in the Y direction. Each of the plurality of portions 115c is connected between the portion 115a and the portion 115b in the Z direction. The plurality of portions 115c each have a width in the Y direction that is narrower than portions 115a and 115b. The plurality of portions 115c each have a thickness in the X direction that is equal to that of portion 115a. This allows the claw portions 115 to function as members for preventing the display 12 from slipping out.
[0047] The abutment member 116 is disposed at a position on the -Y side of the center on the inner surface 11b. The abutment member 116 extends in the Z direction on the inner surface 11b. The abutment member 116 extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. This allows the abutment member 116 to abut against the inner surface 11b at a position on the inner surface 11b corresponding to the claw portion 114.
[0048] As shown in FIG. 12, the abutment member 116 has a portion 116a and a portion 116b. The portion 116a extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The portion 116b is connected to the portion 116a in the X direction and extends on the inner surface 11b from the end on the -Z side to a Z position beyond the end on the +Z side. The width of the portion 116b in the Y direction is narrower than that of the portion 113a. This gives the abutment member 116 relatively high rigidity in the X direction, and the inner surface 11b can be used as a reference abutment surface.
[0049] Here, the abutment member 116 is disposed at a position on the inner surface 11b corresponding to the claw portion 114. The abutment member 116 is located within a Y-direction threshold distance Lth from an imaginary line VL2 that passes through the claw portion 114 and extends in the X-direction. The Y-direction distance L2 (see FIG. 5) between the abutment member 116 and the claw portion 114 is equal to or less than the Y-direction threshold distance Lth. The Y-direction threshold distance Lth can be experimentally determined in advance as a distance at which the claw portion 114 and the abutment member 116 can cooperate to position the display 12. The Y-direction threshold distance Lth may be, for example, 30 mm.
[0050] When the frame 11 is fitted to the frame 124, the portion 114a abuts against the end face 12a. The portion 114b is spaced apart from the end face 12a in the X direction. The portions 114c_1 and 114c_2 are each spaced apart from the end face 12a in the X direction. The portion 116a is spaced apart from the end face 12b in the X direction.

[0073] As described above, in the display device 1 of this embodiment, the frame 11 has, on its inner surface 11a, the claw portions 111 and 114 that can fit into the protrusions 1241 and 1244 on the end surface 12a of the frame 124, and has, on its inner surface 11b, the abutting members 113 and 116 that can abut against the end surface 12b of the display 12. The elastic modulus of the claw portion 111 in the X direction is greater than the elastic modulus of the abutting member 113 in the X direction, and greater than the elastic modulus of the claw portion 112 in the X direction. The rigidity of the abutting member 113 in the X direction is greater than the rigidity of the claw portion 111 in the X direction, and greater than the rigidity of the claw portion 112 in the X direction. This allows the abutting member 113 to use the inner surface 11b as a reference abutment surface, and the claw portion 111 functions as a leaf spring to urge the display 12 toward the inner surface 11b. Therefore, the display 12 can be properly positioned relative to the frame 11 in the X direction.
[0074] As a first modified example of the embodiment, the display device 1i may be configured such that the frame 11i corresponds to the optical member 14i, as shown in Fig. 13. Fig. 13 is an enlarged cross-sectional view showing the configuration of the frame 11i in the first modified example of the embodiment, and shows a cross section corresponding to the cross section taken along line AA in Fig. 2.
[0075] A display device 1i shown in FIG. 13 has a frame 11i instead of the frame 11 (see FIG. 3), and further has an optical member 14i, an adhesive layer 15i, a connecting member 16i, and a light-shielding layer 17i.
[0076] The optical member 14i covers the front surface 12f of the display 12 when the frame 11i is fitted into the frame 124. The display 12 includes a display main body 121, a light guide plate 122, a case 123, and a frame 124, similar to the embodiment. The display main body 121 extends like a plate in the X and Y directions, and its -Z side surface forms the front surface 12f. The light guide plate 122 is disposed on the +Z side of the display main body 121 and extends like a plate in the X and Y directions. The case 123 is disposed on the +Z side of the display main body 121 and the light guide plate 122, and abuts against the edge of the +Z side surface of the display main body 121 while accommodating the light guide plate 122. The frame 124 is disposed so as to cover the display main body 121, the light guide plate 122, and the case 123 from the outside in the X and Y directions, and its outer surface in the X and Y directions forms the end faces 12a to 12d. The frame 124 may further have a rim portion 124a extending inward in the XY directions from the ends on the -Z side of the end faces 12a to 12d. At least the portions of the frame 124 that form the end faces 12a to 12d may be made of a material containing metal as a main component.
[0077] The optical member 14i is translucent. The optical member 14i is also called a cover panel and can protect the display 12 from external impacts and the like.
[0078] The optical member 14i may have a multi-layer structure. The optical member 14i includes a cover glass 141, a layer 142, a layer 143, a layer 144, a layer 145, and a layer 146. The layers 146, 145, 144, 143, 142, and the cover glass 141 are stacked in this order in the Z direction. The layers 146, 145, 144, 143, 142, and the cover glass 141 each extend like a plate in the X and Y directions and have a substantially rectangular shape with the X direction as the longitudinal direction. The cover glass 141 may extend further outward in the X and Y directions than the layers 146, 145, 144, 143, and 142. The cover glass 141 and the layers 142 to 146 each have light-transmitting properties. The layers 142 to 146 are configured to be able to realize a VRM (Variable Reflectance Mirror) function. When the display device 1i has a VRM function, in the mirror mode, the display device 1i may change the reflectance of the display area according to the brightness of the reflected image, etc.
[0079] The frame 11i has a wall portion 11i1, a frame portion 11i2, and a protrusion portion 11i3. The wall portion 11i1 extends in a generally cylindrical shape with its axis in the Z direction and forms inner surfaces 11a to 11d. The wall portion 11i1 may have a generally cylindrical shape that slopes outward toward the +Z side. The frame portion 11i2 extends inward in the XY directions from the -Z side end of the wall portion 11i1 and covers the edge of the back surface of the optical member 14i. The frame portion 11i2 forms an opening 11e (see FIG. 3) for exposing the front surface 12f of the display 12. The protrusion portion 11i3 protrudes in the -Z direction from the -Z side end of the wall portion 11i1. The protrusion portion 11i3 may protrude to the vicinity of the outer edge of the cover glass 141 in the XY directions.
[0080] The adhesive layer 15i is disposed between the rear surface of the optical member 14i and the -Z side surface of the frame portion 11i2. The adhesive layer 15i may be a member such as double-sided tape with adhesive applied to both the +Z side surface and the -Z side surface.
[0081] The adhesive layer 16i is disposed between the +Z side surface of the frame portion 11i2 and the -Z side surface of the frame portion 124a. The adhesive layer 16i may be a member such as double-sided tape with adhesive applied to the +Z side surface and the -Z side surface.
[0082] The light-shielding layer 17i is inserted between the back surface of the cover glass 141 and the layer 142 of the optical member 14i. The light-shielding layer 17i covers the edge portion of the back surface of the cover glass 141. The light-shielding layer 17i has an opening corresponding to the opening 11e. As a result, the light-shielding layer 17i selectively blocks light from entering the region corresponding to the frame portion 11i2.
[0083] The color of the light-shielding layer 17i preferably corresponds to the color of the display area when the surface 1a is observed from the -Z side. The light-shielding layer 17i may be formed by depositing a material of a color corresponding to the display area on the edge of the rear surface of the cover glass 141.
[0084] As in the embodiment, the frame 11i has claw portions 111, 114 on the inner surface 11a that can fit into the protrusions 1241, 1244 on the end surface 12a of the display 12, and abutment members 113, 116 on the inner surface 11b that can abut against the end surface 12b of the display 12.
[0085] In such a display device 1i, the abutting member 113 can use the inner surface 11b as a reference abutment surface, and the claw portion 111 functions as a leaf spring to urge the display 12 toward the inner surface 11b. Therefore, the display 12 can be properly positioned in the X direction with respect to the frame 11i.
[0086] Alternatively, as a second modified example of the embodiment, a display device 1j may be configured such that a frame 11j corresponds to an optical member 14j, as shown in Fig. 14. Fig. 14 is an enlarged cross-sectional view showing the configuration of a frame 11j in the second modified example of the embodiment, and shows a cross section corresponding to the cross section taken along line AA in Fig. 2.
[0087] A display device 1j shown in FIG. 14 has a frame 11j, an optical member 14j, and a light-shielding layer 17j instead of the frame 11i, the optical member 14i, and the light-shielding layer 17i (see FIG. 13).
[0088] Optical member 14j omits layers 144 and 145 from optical member 14i. Layers 142, 143, and 146 do not have a VRM function. Optical member 14j has a smaller Z-thickness than optical member 14i, corresponding to the fewer layers. Otherwise, optical member 14j is similar to optical member 14i.
[0089] Frame 11j has a protrusion 11c whose Z height is lower than that of protrusion 11j3 of frame 11i. Otherwise, frame 11j is similar to frame 11i.
[0090] The light-shielding layer 17j is inserted between the back surface of the layer 146 and the adhesive layer 15i. The light-shielding layer 17j covers the edge of the back surface of the layer 146. The light-shielding layer 17j has an opening corresponding to the opening 11e. This allows the light-shielding layer 17j to selectively shield the area corresponding to the frame portion 11i2 from light.
[0091] The color of light-shielding layer 17j preferably corresponds to the color of the display area when surface 1a is observed from the -Z side. Light-shielding layer 17j may be formed by applying a material of a color corresponding to the display area to the back surface of layer 146, or by attaching a sheet of a material of a color corresponding to the display area to the back surface of layer 146.
[0092] As in the embodiment, the frame 11j has claw portions 111, 114 on the inner surface 11a that can fit into the protrusions 1241, 1244 on the end surface 12a of the display 12, and abutment members 113, 116 on the inner surface 11b that can abut against the end surface 12b of the display 12.
[0093] In such a display device 1j, the abutting member 113 can use the inner surface 11b as a reference abutment surface, and the claw portion 111 functions as a leaf spring to urge the display 12 toward the inner surface 11b. Therefore, the display 12 can be properly positioned in the X direction with respect to the frame 11j.
[0094] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
