Description

Technical Field

[0001] The present disclosure relates to a display device and an electronic device. Background Art

[0002] In recent years, electronic devices equipped with display devices such as viewfinders and head mounted displays (HMDs) that provide augmented reality (AR) and virtual reality (VR) have been actively developed in addition to television devices, monitors, etc. In these electronic devices, it is necessary to further widen the image display surface of the display device that displays an image while reducing the external shape.

[0003] The display device is provided with a display unit including a plurality of light-emitting elements at the center, for example, and a circuit unit including a driving circuit of the display unit is provided around the display unit (i.e., at the peripheral portion of the display device). Then, although the driving circuit is provided with wiring and electrodes including a metal film, external light or the like incident from the outside of the display device may be reflected by such wiring or the like. Such reflected light causes white blurring on the periphery of an image displayed on an image display surface, and thus deteriorates image quality. Therefore, the display device disclosed in Patent Document 1 or the like is provided with an outer frame that surrounds the periphery of the display device and does not transmit light.

[0054] <<1. Background of the embodiments of the present disclosure created by the present inventors>>

[0055] First, before describing the details of the embodiments of the present disclosure, reference will be made to Figures 1 to 3The background against which the inventors have created embodiments of the present disclosure is described. Figure 1 1 and 2 are schematic plan views of a display device 100 according to an embodiment of the present disclosure and a display device 100 a of a comparative example. Figure 2 and Figure 3 is a cross-sectional view of a display device 100a according to a comparative example, and specifically corresponds to a cross-sectional view taken along Figure 1 A cross section of the display device 100a is taken along the line AA' shown in FIG. Figure 2 and Figure 3 , the vertical direction of the stacked structure of the display device 100a corresponds to the relative direction when the display device 100a is arranged so that light emitted by the display device 100a is directed upward from below. Here, the comparative example represents the display device 100a that the inventors have studied before making the embodiments of the present disclosure.

[0056] As described above, in recent years, in addition to television devices, monitors, etc., electronic devices equipped with display devices such as viewfinders and HMDs that provide AR and VR have been actively developed. In these electronic devices, it is necessary to further widen the image display surface of the display device that displays the image while reducing the external shape. Hereinafter, an outline of such a display device 100a will be described.

[0057] Specifically, the display device 100a of the comparative example has a stacked structure in which a back (BP) substrate 200 and an opposing substrate 300 are stacked on each other (see Figure 2 ).like Figure 1 As shown, a display unit 102 including a plurality of light emitting elements (e.g., light emitting diode (LED) elements) (not shown) is provided at a central position when viewed from above the display device 100, and each light emitting element radiates light to form an image. In addition, a circuit unit 104 including a driving circuit for driving the light emitting elements is provided around the display unit 102.

[0058] Specifically, Figure 2 As shown, a light emitting unit 202 including a plurality of light emitting elements (not shown) and a driving circuit unit 204 disposed around the light emitting unit 202 and including a driving circuit for driving the light emitting elements are disposed on the BP substrate 200 side. On the other hand, a color filter (CF) unit 302 including a material that transmits light (such as glass) and including a plurality of color filters (not shown) that transmit light from the light emitting elements is disposed on the counter substrate 300 side. In addition, the CF unit 302 is disposed to face the light emitting unit 202.

[0059] like Figure 2As shown, the BP substrate 200 and the counter substrate 300 stacked on each other are sealed by a resin 452 located between the BP substrate 200 and the counter substrate 300. In addition, the peripheral portion of the display device 100a is sealed by a sealing member 450 including resin.

[0060] By the way, if Figure 2 As shown, since the driving circuit unit 204 is provided with wiring and electrodes including a metal film, light from the light-emitting element of the display device 100a and external light incident from the outside of the display device 100a are reflected by the metal film. As a result, the reflected light generates white blur at the periphery of the image displayed on the display device 100a, deteriorating the image quality, and ultimately reducing the immersive effect of the image.

[0061] Therefore, if Figure 3 As shown, the display device 100a according to the comparative example is provided with an outer frame 454 that surrounds the periphery of the display device 100a and does not transmit light. In the comparative example, by providing such an outer frame 454, reflection of light on the metal film of the driving circuit unit 204 can be suppressed, and degradation of image quality can be avoided.

[0062] However, since the provision of the outer frame 454 leads to an increase in the number of parts and the number of processes, it is difficult to suppress an increase in the manufacturing cost of the display device 100 a.

[0063] Therefore, in order to suppress the increase in manufacturing cost while suppressing the reflection of light on the metal film of the driving circuit unit 204, the present inventors have conducted intensive research. Then, the present inventors have created the following embodiment of the present disclosure, which has a configuration of the display device 100 that does not intentionally include the external frame 454 as described above. Hereinafter, the details of this embodiment of the present disclosure will be described sequentially.

[0064] <<2. First embodiment>>

[0065] First, refer to Figure 4 A display device 100 according to a first embodiment of the present disclosure is described. Figure 4 is a cross-sectional view of a display device 100 according to a preset embodiment, and specifically corresponds to a cross-sectional view along Figure 1 A cross-sectional view of the display device 100 taken along the line AA' shown in FIG. Figure 4 , the vertical direction of the stacked structure of the display device 100 corresponds to a relative direction in a case where the display device 100 is arranged such that light emitted by the display device 100 is directed upward from below.

[0066] Specifically, in this embodiment, if Figure 4As shown, the display device 100 has a stacked structure in which a BP substrate (first substrate) 200 and an opposing substrate (second substrate) 300 are stacked on each other. In this embodiment, as in the comparative example, a light-emitting unit (display unit) 202 including a plurality of light-emitting elements (not shown) and a driving circuit unit 204 disposed around the light-emitting unit 202 and including a driving circuit for driving the light-emitting elements are disposed on the BP substrate 200. A CF unit 302 including a material such as glass that transmits light from the light-emitting elements and including a plurality of color filters (not shown) that transmit light from the light-emitting elements is disposed on the opposing substrate 300. Then, the CF unit 302 is disposed to face the light-emitting unit 202.

[0067] like Figure 4 As shown, the BP substrate 200 and the counter substrate 300 stacked on each other are sealed by a resin 452 located between the BP substrate 200 and the counter substrate 300 and including, for example, a photocurable resin. In addition, the outer periphery of the stacked structure of the display device 100 when viewed from above is sealed by, for example, a sealing member (photocurable resin) 450 containing a photocurable resin. In the display device 100 having such a sealing structure, moisture is prevented from entering the interior of the display device 100, and the occurrence of substrate peeling and the like is suppressed.

[0068] In addition, in this embodiment, if Figure 4 As shown, a light shielding film (first light shielding film) 402 is provided to cover at least a portion of the driving circuit unit 204 of the BP substrate 200. In addition, in the present embodiment, a light shielding film (second light shielding film) 404 covering at least a portion of a region not facing the light emitting unit 202, in other words, at least a portion of a region facing the driving circuit unit 204, is provided on the surface of the counter substrate 300 facing the BP substrate 200. In the following description, a structure in which the light shielding films 402 and 404 are provided on the BP substrate 200 side and the counter substrate 300 side is referred to as a light shielding structure.

[0069] Specifically, in Figure 4 In the illustrated embodiment, the light shielding film 402 on the BP substrate 200 side covers the top surface and the side surfaces of the driving circuit unit 204 to suppress the reflection of light on the metal film of the driving circuit unit 204. In addition, the light shielding film 404 on the counter substrate 300 side covers the area of ​​the counter substrate 300 facing the driving circuit unit 204 to suppress the light from outside the display device 100 from reaching the metal film of the driving circuit unit 204 and being reflected.

[0070] exist Figure 4In the illustrated embodiment, the light shielding films 402 and 404 are arranged so that the entire light shielding film 402 and the entire light shielding film 404 face each other. In other words, the light shielding films 402 and 404 are arranged so that the entire light shielding film 402 and the entire light shielding film 404 overlap each other.

[0071] That is, in this embodiment, due to the light shielding structure in which the light shielding films 402 and 404 are provided on the BP substrate 200 side and the counter substrate 300 side, the reflection of light on the metal film of the driving circuit unit 204 can be more reliably suppressed, and the degradation of the image quality can be avoided. In addition, this embodiment (which does not provide the outer frame 454 surrounding the periphery of the display device 100) can suppress the increase in the manufacturing cost of the display device 100.

[0072] Note that in this embodiment, Figure 4 The shading structure shown in FIG. Figure 1 The rectangular display device 100 shown in FIG. 1 is provided on all four sides. However, this embodiment does not require that the display device 100 have all four sides. Figure 4 For example, in the case where the light shielding film 402 and the sealing member 450 cannot be formed of materials having high adhesion to each other, the light shielding structure may be provided on one or more sides (one or more and three or less) of the rectangular display device 100 so as to more reliably ensure the sealing of the display device 100 by the sealing member 450. In addition, in the present embodiment, the light shielding structure may be provided on the entire side of the rectangular display device 100, or may be provided on a portion of each side.

[0073] As described above, the light shielding structure according to the present embodiment can more reliably suppress the reflection of light on the metal film of the driving circuit unit 204. In addition, the present embodiment, which does not provide the outer frame 454 surrounding the periphery of the display device 100, can suppress an increase in the manufacturing cost of the display device 100. Note that the detailed configuration of the light shielding films 402 and 404 according to the present embodiment will be described later.

[0074] <<3. Second Embodiment>>

[0075] Next, we will refer to Figures 5 to 7 A second embodiment of the present disclosure is described. Figure 5 and Figure 6 is a cross-sectional view of a display device 100a according to a comparative example, and Figure 7 is a cross-sectional view of a display device 100 according to this embodiment. Specifically, Figures 5 to 7 Corresponding to when the display devices 100 and 100a are along Figure 1, and corresponds to the relative directions when the display devices 100 and 100a are arranged so that the light emitted by the display devices 100 and 100a is directed upward from below. Here, as described above, the comparative example means the display device 100a that the inventors have studied before creating the embodiments of the present disclosure.

[0076] As described above, the first embodiment of the present invention in which the light shielding films 402 and 404 are provided on both the BP substrate 200 side and the counter substrate 300 side can suppress the reflection of light on the metal film of the driving circuit unit 204. However, from the viewpoint of suppressing the reflection of light on the driving circuit unit 204, as Figure 5 As shown, even if the stacked structure of the light shielding film 402 is provided only on the BP substrate 200 side, the reflection of light on the driving circuit unit 204 can be suppressed, although not as reliably as in the first embodiment. Figure 6 As shown, even a stacked structure in which the light shielding film 404 is provided only on the counter substrate 300 side can suppress light reflection on the drive circuit unit 204, although not as reliably as in the first embodiment.

[0077] However, in Figure 5 In the comparative example shown, in order to more reliably suppress the reflection of light at the driving circuit unit 204 by the light shielding film 402 provided only on the BP substrate 200 side, the light shielding film 402 is provided to cover the entire top surface and side surfaces of the driving circuit unit 204. In this case, although the reflection of light can be suppressed, since the light shielding film 402 includes a material (e.g., silicon oxide (SiO2) or the like) having lower adhesion to the sealing member 450 than the upper surface of the driving circuit unit 204, it is difficult to more reliably ensure sealing by the sealing member 450 of the display device 100a. In addition, when the sealing is insufficient, moisture may enter the interior of the display device 100a, and peeling or the like may occur.

[0078] Therefore, in order to ensure the adhesion between the light shielding film 402 and the sealing member 450, it is necessary to set the contact area between the driving circuit unit 204 and the sealing member 450 to a predetermined size or more, and therefore, it is difficult to provide the light shielding film 402 to cover the entire top surface and side surfaces of the driving circuit unit 204. In addition, in the future, as the frame becomes narrower (specifically, the driving circuit unit 204 becomes thinner or narrower), it is considered difficult to ensure that the contact area between the driving circuit unit 204 and the sealing member 450 is greater than or equal to the predetermined size.

[0079] exist Figure 6In the comparative example shown, in order to more reliably suppress the reflection of light on the driving circuit unit 204 by the light shielding film 404 provided only on the side of the counter substrate 300, the light shielding film 404 is provided so as to cover the entire area facing the driving circuit unit 204 on the upper surface of the counter substrate 300 facing the BP substrate 200. In this case, although the reflection of light can be suppressed, the light from the outside of the display device 100a is blocked by the light shielding film 404. Therefore, during manufacturing, the light does not reach the sealing member 450 and the resin 452 inside the display device 100a, and the possibility of insufficient curing of the sealing member 450 and the resin 452 becomes high. In addition, when the curing is insufficient, moisture may enter the inside of the display device 100a, and peeling and the like may occur.

[0080] Therefore, in a second embodiment of the present disclosure, a light-shielding structure is proposed that can ensure the contact area between the driving circuit unit 204 and the sealing member 450 of a predetermined size or larger and fully photo-cure the sealing member 450 and the resin 452 while more reliably suppressing the reflection of light on the metal film of the driving circuit unit 204.

[0081] Specifically, Figure 7 As shown, in the present embodiment, the light shielding film 402 disposed on the BP substrate 200 side is disposed to cover only a portion of the driving circuit unit 204, and the light shielding film 404 disposed on the counter substrate 300 side is disposed to cover only a portion of the region of the counter substrate 300 facing the driving circuit unit 204. In the present embodiment, since the light shielding film 402 on the BP substrate 200 side is disposed to expose a portion of the driving circuit unit 204, the top surfaces of the sealing member 450 and the driving circuit unit 204 can directly contact each other.

[0082] In addition, in this embodiment, the light shielding films 402 and 404 are not provided so that the entire light shielding film 402 and the entire light shielding film 404 completely overlap each other. Figure 7 In the embodiment shown, the light shielding films 402 and 404 are arranged so that a portion of the light shielding film 402 and a portion of the light shielding film 404 face each other (overlap), and the remaining portion of the light shielding film 402 and the remaining portion of the light shielding film 404 do not face each other (do not overlap). Note that this embodiment is not limited to Figure 7 The form shown in the figure, and the light shielding films 402 and 404 can be arranged to alternate in the stacking direction to suppress the reflection of light on the metal film of the driving circuit unit 204. That is, in this embodiment, the light shielding films 402 and 404 can be arranged so that the entire light shielding film 402 and the entire light shielding film 404 do not completely overlap each other.

[0083] In the present embodiment, the light shielding film 404 provided on the counter substrate 300 side is provided to cover only a portion of the region of the counter substrate 300 facing the driving circuit unit 204. Therefore, in the present embodiment, since light from outside the display device 100 is not completely shielded by the light shielding film 404, at the time of manufacturing, the light reaches the sealing member 450 and the resin 452 inside the display device 100. Therefore, the present embodiment enables the sealing member 450 and the resin 452 inside the display device 100 to be sufficiently cured, and thus peeling or the like due to moisture entering the display device 100 can be prevented from occurring.

[0084] In this embodiment, since light that cannot be blocked by the light blocking film 404 disposed on the counter substrate 300 side can also be blocked by the light blocking film 402 disposed on the BP substrate 200 side, reflection of light on the metal film of the driving circuit unit 204 can be suppressed.

[0085] In addition, in this embodiment, since the light shielding film 402 provided on the BP substrate 200 side only covers a part of the driving circuit unit 204 and does not cover the entire driving circuit unit 204, the upper surfaces of the sealing member 450 and the driving circuit unit 204 can be in direct contact with each other. Therefore, in this embodiment, it is easy to set the contact area between the driving circuit unit 204 and the sealing member 450 to be above a predetermined size. In addition, in this embodiment, even in the case where the frame is narrow, it is easy to ensure that the contact area between the driving circuit unit 204 and the sealing member 450 is above a predetermined size. That is, in this embodiment, the contact area between the driving circuit unit 204 and the sealing member 450 can be equal to or greater than the predetermined size, and the adhesion between the light shielding film 402 and the sealing member 450 can be ensured. Therefore, in this embodiment, since the sealing of the sealing member 450 by the display device 100 can be fully ensured, it is possible to avoid peeling due to moisture entering the display device 100.

[0086] <<4. Third embodiment>>

[0087] Next, we will refer to Figures 8 to 11 A display device 100 according to a third embodiment of the present disclosure is described. Figure 8 and Fig. 9 is a cross-sectional view of a display device 100 according to a preset embodiment, and specifically corresponds to a cross-sectional view along Figure 1 A cross-sectional view of the display device 100 taken along the line AA' shown in FIG. Figure 8 and Fig. 9 , the vertical direction of the stacked structure of the display device 100 corresponds to the relative direction in the case where the display device 100 is arranged so that the light emitted by the display device 100 is directed upward from below. In addition, Fig.10 and Fig.11 4 is a plan view of the light shielding film 404 according to the present embodiment.

[0088] In the described second embodiment, the light shielding film 404 provided on the counter substrate 300 side is provided to cover only a portion of the region of the counter substrate 300 facing the drive circuit unit 204. Then, with this configuration, in the second embodiment, since light from outside the display device 100 is not completely blocked by the light shielding film 404, the light reaches the sealing member 450 and the resin 452 inside the display device 100 at the time of manufacturing. Therefore, in the third embodiment of the present disclosure, as in the second embodiment, an opening is provided in the light shielding film 404 so as to deliver light to the sealing member 450 and the resin 452 inside the display device 100 at the time of manufacturing.

[0089] Specifically, in this embodiment, if Figure 8 As shown, the light shielding film 404 provided on the counter substrate 300 side has an opening (opening) 406 for guiding light from the outside of the display device 100 to the sealing member 450 and the resin 452 inside the display device 100. Therefore, in this embodiment, since the light from the outside of the display device 100 can be effectively guided to the sealing member 450 and the resin 452 inside the display device 100 through the opening 406, the light more reliably reaches the sealing member 450 and the resin 452 inside the display device 100 during manufacturing. Therefore, this embodiment contributes to sufficient curing of the sealing member 450 and the resin 452 inside the display device 100, and thus it is possible to further prevent peeling or the like due to moisture entering the display device 100.

[0090] Note that in this embodiment, if Fig. 9 As shown, the number of the openings 406 provided in the light shielding film 404 is not limited to one, and may be plural.

[0091] In addition, in this embodiment, because the number of openings 406 is not limited, the light shielding film 404 may have one or more rectangular slits, or may have a lattice shape or a checkered pattern shape. In this embodiment, the shape of the opening 406 is not limited to a rectangular shape, and may be, for example, a circular shape, an elliptical shape, a polygonal shape, etc.

[0092] For example, in this embodiment, the light shielding film 404 may have Fig.10 The grid shape shown in or Fig.11 The checkered pattern shown in .

[0093] However, in the present embodiment, in order to sufficiently cure the sealing member 450 and the resin 452 inside the display device 100, the area of ​​the opening 406 of the light shielding film 404 when viewed from above is preferably 25% or more of the entire area of ​​the light shielding film 404 when viewed from above (the area of ​​the light shielding film 404 including the opening 406). Specifically, the inventors prepared the light shielding film 404 in which the area of ​​the opening 406 was changed differently, and irradiated ultraviolet (UV) light from the outside of the display device 100 to confirm whether the sealing member 450 and the resin 452 inside the display device 100 were sufficiently cured. As a result, it can be confirmed that when the area of ​​the opening 406 was 25% and 50%, the sealing member 450 and the resin 452 inside the display device 100 were sufficiently cured. Therefore, in the present embodiment, the area of ​​the opening 406 of the light shielding film 404 when viewed from above is preferably more than 25% of the entire area of ​​the light shielding film 404 when viewed from above.

[0094] In the present embodiment, as long as the light shielding films 402 and 404 are arranged to suppress reflection of light on the metal film of the driving circuit unit 204, for example, so as to be staggered at least in the stacking direction, the light shielding film 402 on the BP substrate 200 side may also have an opening 406. In addition, in the present embodiment, as long as the light shielding films 402 and 404 are arranged to be staggered at least in the stacking direction so as to suppress reflection of light on the metal film of the driving circuit unit 204, the light shielding film 402 may also have one or more slits, a lattice shape, or a checkered pattern shape.

[0095] As described above, in this embodiment, since light from outside the display device 100 can be effectively guided to the sealing member 450 and the resin 452 inside the display device 100 through the opening 406, light more reliably reaches the sealing member 450 and the resin 452 inside the display device 100 during manufacturing. Therefore, this embodiment helps to fully cure the sealing member 450 and the resin 452 inside the display device 100, and thus peeling or the like due to moisture entering the display device 100 can be further avoided.
