[0010] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe a number of features, not all of these features are essential to the invention, and the features may be combined in any manner. Furthermore, in the accompanying drawings, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0011] (First embodiment) The electronic module according to this embodiment will be described with reference to Figures 1 to 3 and Figure 16. Figure 1 is a plan view of the electronic module according to this embodiment, Figure 2(a) is a cross-sectional view taken along line A-A' in Figure 1(a), and Figure 2(b) is a cross-sectional view taken along line B-B' in Figure 1(b). Figures 3(a) and (b) are enlarged views of Figure 2. Figure 16 is a cross-sectional view of a conventional electronic module.

[0012] The first substrate 100 has a display area AA and a peripheral area PA. As shown in FIG. 1, the first substrate 100 has a rectangular shape in a plan view. The shape of the first substrate 100 in a plan view may be a square or a rectangle. In addition, certain corners may be chamfered at the apexes of each side (side surface). The first substrate 100 may have a light-emitting portion in the display area AA.

[0013] Furthermore, the first substrate 100 may have an electrode portion 101. The electrode portion 101 may be provided on the outer periphery of the peripheral area PA in a plan view, or may be provided so that at least a portion of the electrode portion 101 overlaps with the peripheral area PA as shown in FIG. 1(b). By providing at least a portion of the electrode portion 101 so that it overlaps with the peripheral area PA, it is possible to further reduce the size of the electronic module. In particular, by providing the electrode portion 101 on the peripheral area PA, it is possible to further reduce the size of the electronic module.

[0014] The frame member 200 is disposed on the first substrate 100 as shown in FIG. 1. Specifically, the frame member 200 is disposed on the peripheral region of the first substrate 100. In a plan view, the frame member 200 has a rectangular tubular shape larger than the first substrate 100, and is disposed so as to surround the display region. The material constituting the frame member 200 is not particularly limited, but may be a light-absorbing material. Alternatively, it may be a liquid crystal polymer. By using these materials, the influence of external light can be reduced.

[0015] 2, the frame member 200 has an overlapping portion 206 that overlaps with the first substrate 100. The overlapping portion 206 may be disposed so as to surround the display area AA.

[0016] 3, the frame member 200 has a first surface 201 facing the first substrate 100, a second surface 202 facing the first surface 201, and an inner wall side surface 207 in contact with the first surface 201 and the second surface 202. Specifically, the inner wall side surface 207 is a surface that is in contact with the first surface 201 and the second surface 202 and is disposed on the display area AA side. The inner wall side surface 207 has at least a first end surface 203 in contact with the first surface 201 and a second end surface 204 in contact with the second surface 202. In a cross-sectional view passing through the first substrate 100 and the frame member 200, the electronic module according to this embodiment is an embodiment in which the first end surface 203 and the second end surface 204 are not curved.

[0017] A normal line to the second surface 202 is defined as a first line. Specifically, in a cross-sectional view passing through the first substrate 100 and the frame member 200, a line passing through a point where the second surface 202 and the second end surface 204 contact each other is defined as a first line. In this case, an angle between the first line and the first end surface 203 is defined as θ1, and an angle between the first line and the second end surface 204 is defined as θ2. FIG. 3(b) is a cross-sectional view showing the relationship between θ1 and θ2 using FIG. 3(a).

[0018] At this time, θ1 and θ2 are different from each other. Specifically, θ1 is 10° or more, preferably 20° or more, and more preferably larger than 23°. Moreover, θ1 is 50° or less, and preferably 40° or less. θ2 is 2° or more, and preferably larger than 3°. This is because friction between the mold and the frame member 200 can be further suppressed, and therefore protrusions generated on the second end surface 204 can be further suppressed. Moreover, θ2 is 20° or less, and preferably 10° or less. This is because the strength of the frame member 200 can be maintained.

[0019] In the electronic module according to the present invention, the angle between the first line and the second end face 204 is θ2, which can reduce protrusions generated on the second end face 204. Therefore, the electronic module according to the present embodiment can suppress deterioration in the quality of the displayed image.

[0020] Here, a conventional electronic module and an electronic module according to the present invention will be compared with each other with reference to FIG. 16. In the conventional electronic module, the first line and the second end face 204 do not form an angle. In other words, the first line and the second end face 204 are parallel to each other. With such a configuration, friction is likely to occur between the mold and the frame member 200 when the frame member 200 is formed. As a result, a protrusion is generated on the second end face 204, and the generated protrusion overlaps with the display area, causing a deterioration in the quality of the displayed image.

[0021] In contrast, in the electronic module according to the present invention, the first line and the second end face 204 form an angle of θ2. In other words, the first line and the second end face 204 are not parallel. With this configuration, it is possible to reduce friction between the mold and the frame member when forming the frame member 200. As a result, it is possible to suppress the occurrence of protrusions on the second end face 204.

[0022] As a result, the electronic module according to this embodiment can suppress degradation of the quality of a displayed image.

[0023] Moreover, the electronic module according to this embodiment preferably has the following configuration.

[0024] A line that passes through a point where the first end surface 203 and the second end surface 204 meet and is parallel to the second surface 202 is defined as a second line. In this case, the distance between the first surface 201 and the second line in a direction perpendicular to the second surface 202 is defined as a first distance d1, and the distance between the second surface 202 and the second line is defined as a second distance d2. The distance between the first surface 201 and the second surface 202 in a direction perpendicular to the second surface 202 is defined as a distance D. FIG. 3(b) is a cross-sectional view showing the relationship between the first distance d1, the second distance d2, and the distance D using FIG. 3(a).

[0025] The first distance d1, the second distance d2, and the distance D may be defined at a position where the distance D is the largest, or may be defined at a position where the distance D is the smallest, or may be defined at other positions. For example, in the electronic module according to this embodiment, the first surface 201 and the second surface 202 are arranged parallel to each other, so that the first distance d1, the second distance d2, and the distance D can be defined at any positions.

[0026] At this time, in the electronic module according to the present invention, it is preferable that the second distance d2 is 10% or more of the distance D. This is because the strength of the frame member 200 can be maintained by having the second distance d2 be 10% or more of the distance D. Specifically, the second distance d2 may be 10% or more and 90% or less of the distance D between the first surface 201 and the second surface 202, and is preferably 20% or more and 50% or less.

[0027] In particular, when the second distance d2 is large, this is preferable from the viewpoint of the strength of the frame member 200 itself. Also, when the first distance d1 is large, this is preferable because it can suppress diffuse reflection due to stray light from the display area AA. As a result of intensive research by the present inventors into these viewpoints, it is preferable that the second distance d2 is equal to or smaller than the first distance d1, and specifically, it is preferable that the second distance d2 is equal to or larger than 25% and equal to or smaller than 50% of the first distance d1.

[0028] At this time, the electronic module according to this embodiment can further suppress deterioration in the quality of the displayed image while maintaining the strength of the frame member 200.

[0029] Second embodiment An electronic module according to a second embodiment will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a plan view of the electronic module according to the present embodiment, Fig. 5 is a cross-sectional view taken along line CC' in Fig. 4, and Fig. 6 is an enlarged view of Fig. 5.

[0030] The electronic module of this embodiment differs from the first embodiment in that the first substrate 100 and the second substrate 300 are connected via a bonding member 600, the first substrate 100 and the third substrate 400 are connected via an electrode portion 101, and the electronic module has members that contact the side of the second substrate 300, the side of the bonding member 600, and the side of the third substrate.

[0031] In this embodiment, the second substrate 300 has a display area AA and a peripheral area PA. The first substrate 100 may be a support substrate, and the second substrate 300 may have a light-emitting portion in the display area AA. The coupling member 600 is disposed on a first main surface of the first substrate 100, and the first substrate 100 and the second substrate 300 are connected via the coupling member 600. The first main surface of the first substrate 100 is a surface facing a first surface 201 of the frame member 200.

[0032] The third substrate 400 is connected to the electrode portion 101 of the first substrate 100. The third substrate 400 may be connected to the electrode portion 101 via an Au bump, an anisotropic conductive film, an anisotropic conductive paste, or the like. The third substrate 400 may be a wiring board such as a flexible printed circuit board (FPC).

[0033] 6, in the electronic module according to this embodiment, the member 500 is disposed so as to cover at least a part of the first main surface of the first substrate 100, the side surface of the second substrate 300, the side surface of the coupling member 600, and the end portion of the third substrate 400. As a result, in the electronic module according to this embodiment, the reliability of the connection between the electrode portion 101 of the first substrate 100 and the third substrate 400 is increased.

[0034] In FIG. 6, the member 500 is arranged so as to cover at least a part of the first main surface of the first substrate 100, the side of the second substrate 300, the side of the coupling member 600, and the end of the third substrate 400, but is not limited thereto. The member 500 may be arranged so as to improve the reliability of the connection between the electrode portion 101 and the third substrate 400. Therefore, the member 500 may be arranged so as to cover at least a part of the first main surface of the first substrate 100 and the end of the third substrate 400. More preferably, the member 500 is arranged so as to cover at least a part of the first main surface of the first substrate 100, the side of the second substrate 300, the side of the coupling member 600, and the end of the third substrate 400. As a result, the electronic module according to this embodiment has high reliability of the connection between the electrode portion 101 of the first substrate 100 and the third substrate 400.

[0035] The member 500 is also called a reinforcing member, and specifically may be an acrylic resin, an epoxy resin, or a silicone resin. The reinforcing member may be either a thermosetting resin or an ultraviolet-curing resin, but is preferably an ultraviolet-curing resin. This is because if the member 500 is a thermosetting resin, the reinforcing member may be heated and hardened by heat from the display area AA or sunlight from the outside.

[0036] By having the above configuration, the electronic module according to this embodiment can improve the reliability of the connection between the electrode section 101 and the third substrate 400.

[0037] Third embodiment An electronic module according to a third embodiment will be described with reference to FIG. 7. FIG. 7 is a cross-sectional view of the electronic module according to this embodiment. The electronic module according to this embodiment differs from the first embodiment in that the inner wall side surface 207 has at least a first end surface 203, a second end surface 204, and a third end surface 205 that contacts the first end surface 203 and the second end surface 204. Although only the third end surface 205 is described in this embodiment, the electronic module according to this embodiment may have multiple end surfaces, such as a fourth end surface, between the first end surface 203 and the second end surface 204.

[0038] Here, the normal to the second surface 202 is defined as the first line. Specifically, in a cross-sectional view passing through the first substrate 100 and the frame member 200, the first line passes through the point where the second surface 202 and the second end surface 204 contact each other, and the normal to the second surface 202 is defined as the first line. In this case, the angle between the first line and the first end surface 203 is defined as θ1, the angle between the first line and the second end surface 204 is defined as θ2, and the angle between the first line and the third end surface 205 is defined as θ3.

[0039] Also, a line passing through the point where the second end face 204 and the third end face 205 meet and parallel to the second face 202 is defined as the second line, and a line passing through the point where the third end face 205 and the first end face 203 meet and parallel to the second face 202 is defined as the third line. In this case, the distance between the first face 201 and the third line in the direction perpendicular to the second face 202 is defined as the first distance d1, the distance between the second face 202 and the second line is defined as the second distance d2, and the distance between the second line and the third line is defined as the third distance d3. The distance between the first face 201 and the second face 202 in the direction perpendicular to the second face 202 is defined as the distance D.

[0040] The first distance d1, the second distance d2, the third distance d3, and the distance D may be defined at a position where the distance D is largest, or may be defined at a position where the distance D is smallest, or may be defined at other positions. For example, in the electronic module according to this embodiment, the first surface 201 and the second surface 202 are arranged parallel to each other, so that the first distance d1, the second distance d2, the third distance d3, and the distance D can be defined at any positions.

[0041] Here, FIG. 7(d) is a diagram showing the relationship between θ1, θ2, θ3, the first distance d1, the second distance d2, and the third distance d3 using FIG. 7(a).

[0042] In this case, θ1, θ2, and θ3 are different angles. For example, θ1 is 2° or more and 10° or less, θ2 is larger than θ1 and 89° or less, and θ3 is larger than 0° and 89° or less.

[0043] Moreover, the first distance d1 is 7% or more and 50% or less of the distance D, preferably 10% or more and 50% or less, and more preferably 20% or more and 50% or less. The second distance d2 is 10% or more and 70% or less of the distance D, preferably 10% or more and 50% or less. The third distance d3 is 0% or more and 70% or less of the distance D, preferably 0% or more and 50% or less. Moreover, if the first distance d1 is larger than the second distance d2 and the third distance d3, the strength of the frame member 200 is further improved, which is preferable.

[0044] 7(a) shows a configuration in which the angles are larger in the order of θ1, θ3, and θ2. With such a configuration, the electronic module according to this embodiment can reduce the material forming the frame member 200 while maintaining the strength of the frame member 200. As a result, the electronic module according to this embodiment has high strength and low cost.

[0045] In addition, in FIG. 7(a), θ1 is 20° or more, and preferably 50° or more. θ1 is 80° or less, and preferably 70° or less. θ2 is 2° or more, and preferably greater than 3°. θ2 is 20° or less, and preferably 10° or less. θ3 is 10° or more, and preferably 20° or more. θ3 is 60° or less, and preferably 40° or less.

[0046] 7(b) shows a configuration in which the angles are larger in the order of θ3, θ1, and θ2. With such a configuration, the electronic module according to this embodiment can further reduce the material used to form the frame member 200. Therefore, the electronic module according to this embodiment can be obtained at a lower cost.

[0047] In FIG. 7(b), θ1 is 10° or more, and preferably 20° or more. θ1 is 50° or less, and preferably 40° or less. θ2 is 2° or more, and preferably greater than 3°. θ2 is 20° or more, and preferably 10° or less. θ3 is 20° or more, and preferably 40° or more. θ3 is 80° or less, and preferably 70° or less.

[0048] 7(c) shows a configuration in which the angles are larger in the order of θ3, θ2, and θ1. With such a configuration, the electronic module according to this embodiment can further reduce the material used to form the frame member 200. Therefore, the electronic module according to this embodiment can be obtained at a lower cost.

[0049] 7(c), θ1 may be, for example, 0°. When θ1 is 0°, the first end face 203 is perpendicular to the second face 202, and therefore a protrusion may be formed on the first end face 203. However, in the electronic module according to the present embodiment, the first end face 203 is disposed closer to the peripheral area PA than the second end face 204 and the third end face 205, and therefore even if a protrusion is formed on the first end face 203, the effect on the quality of the display image is small. Therefore, the electronic module according to the present embodiment can be obtained at low cost while suppressing deterioration in the quality of the display image.

[0050] Moreover, θ2 is equal to or greater than 2°, and preferably greater than 3°. Moreover, θ2 is equal to or less than 20°, and preferably equal to or less than 10°. θ3 may be equal to or greater than 80° and equal to or less than 90°, and may be, for example, 90°.

[0051] As described above, the electronic module according to this embodiment is an electronic module that can reduce costs while suppressing deterioration in the quality of a displayed image.

[0052] (Fourth embodiment) An electronic module according to a fourth embodiment will be described with reference to Fig. 8. Fig. 8 is a cross-sectional view of the electronic module according to this embodiment. The electronic module according to this embodiment differs from the first embodiment in that, in a cross-sectional view passing through the first substrate 100 and the frame member 200, the inner wall side surface 207 is a curved surface.

[0053] In the electronic module according to this embodiment, the inner wall side surface 207 is a curved surface. In other words, the end faces of the electronic module do not form corners. Even in the electronic module according to this embodiment, it is possible to reduce friction between the mold and the frame member 200 when forming the frame member. As a result, it is possible to suppress the occurrence of protrusions on the inner wall side surface 207, and therefore to suppress deterioration in image quality.

[0054] Furthermore, in the electronic module according to this embodiment, as described above, the end faces do not form corners. Therefore, the electronic module according to this embodiment is more easily filled with the material that constitutes the frame member 200. Therefore, compared to the other embodiments described above, the generation of air bubbles in the frame member 200 can be suppressed. Therefore, it is possible to suppress diffuse reflection of stray light from the display area AA due to air bubbles in the frame member 200.

[0055] As a result, the electronic module according to this embodiment can further suppress deterioration in the quality of a displayed image.

[0056] Fifth embodiment An electronic module according to a fifth embodiment will be described with reference to Fig. 9. Fig. 9 is a cross-sectional view of the electronic module according to this embodiment.

[0057] Fig. 9(a) differs from the first embodiment in that it has a light-transmitting plate 700 facing the first substrate 100. The electronic viewfinder shown in Fig. 9(a) has the light-transmitting plate 700 facing the first substrate 100, which makes it possible to prevent foreign matter from entering the display area AA from the outside. Therefore, the electronic viewfinder according to this embodiment can prevent degradation of the quality of the displayed image due to the intrusion of foreign matter. The same applies to Fig. 9(b).

[0058] Moreover, the electronic viewfinder according to the present embodiment may have an optical member facing the first substrate 100 instead of the light-transmitting plate 700. The optical member may be disposed above the light-transmitting plate 700 with respect to the first substrate 100 in FIG. 9(a) and FIG. 9(b). Specifically, the optical member may be disposed on the viewer side of the light-transmitting plate 700 in FIG. 9(a) and FIG. 9(b). Specifically, the optical member is a lens or a prism. Providing an optical member facing the first substrate 100 instead of the light-transmitting plate 700 can also suppress the intrusion of foreign matter. Therefore, the degradation of the image quality of the display image due to the intrusion of foreign matter can be suppressed.

[0059] Moreover, the electronic viewfinder according to the present embodiment may have both the light-transmitting plate 700 and the optical member. With such a configuration, the light-transmitting plate 700 can prevent foreign matter from entering, and the optical member can prevent degradation of the quality of the displayed image caused by external light.

[0060] (Application example) Hereinafter, a display device, an imaging device, an electronic device, a wearable device, and an image forming device using an electronic module according to the present invention will be described with reference to FIGS.

[0061] 10 is a schematic diagram showing an example of a display device according to the present embodiment. The display device 1000 may have a touch panel 1003, a display panel 1005, a frame 1006, a circuit board 1007, and a battery 1008 between an upper cover 1001 and a lower cover 1009.
