[Modes for carrying out the invention]
[0013] The display device according to this embodiment will be described below with reference to the drawings.
[0014] <Embodiment 1> The display device 10 according to this embodiment will be described with reference to Figures 1 to 13. The display device 10 is mounted, for example, on a vehicle.
[0015] As shown in Figure 1, the display device 10 comprises a display unit 50, a cover 400, and a waterproof film 500. The display unit 50 displays characters, images, etc. The cover 400 protects the display unit 50. The waterproof film 500 covers the gap 502 between the cover 400 and the side plate 330a of the housing 300 of the display unit 50, which will be described later. In this specification, the longitudinal direction (to the right of the paper) of the display device 10 in Figure 1 is described as the +X direction, the short direction (towards the top of the paper) is described as the +Y direction, and the direction perpendicular to the +X and +Y directions (towards the front of the paper, towards the user) is described as the +Z direction.
[0016] As shown in Figure 2, the display unit 50 comprises a liquid crystal display panel 100, a flexible substrate FL, a backlight 200, and a housing 300. The liquid crystal display panel 100 displays characters, images, etc. The flexible substrate FL connects the liquid crystal display panel 100 to the outside. The backlight 200 is the light source for the liquid crystal display panel 100. The housing 300 houses the liquid crystal display panel 100 and the backlight 200. In Figure 2, for ease of understanding, the flexible substrate FL is shown with a solid line, and the hatching of the waterproof film 500 is omitted. In the following figures, the flexible substrate FL, waterproof film 500, etc., are shown with solid or dashed lines, and hatching may be omitted.
[0017] The liquid crystal display panel 100 of the display unit 50 is, for example, a known transmissive transverse field type liquid crystal display panel. The liquid crystal display panel 100 is actively matrix driven by a TFT (Thin Film Transistor). The liquid crystal display panel 100 modulates light from the backlight 200 to display characters, images, etc.
[0018] As shown in Figure 3, the liquid crystal display panel 100 has a display area 111 and a bezel area 112. The display area 111 is an area where pixels are arranged in a matrix and can display characters, images, etc. The bezel area 112 is an area where wiring, driver ICs (Integrated Circuits) 122, etc., are arranged. The bezel area 112 surrounds the display area 111.
[0019] As shown in Figures 3 and 4, the liquid crystal display panel 100 comprises a TFT substrate 114, a counter substrate 115, liquid crystal 116, a first polarizing plate 117, a second polarizing plate 118, and a driver IC 122. The TFT substrate 114 and the counter substrate 115 sandwich the liquid crystal 116. The first polarizing plate 117 is provided on the TFT substrate 114, and the second polarizing plate 118 is provided on the counter substrate 115. The driver IC 122 is mounted in the bezel region 112.
[0020] The TFT substrate 114 is, for example, a glass substrate. The TFT substrate 114 is located on the -Z side. The main surface 114a of the TFT substrate 114 on the liquid crystal 116 side is provided with a TFT for pixel selection, gate wiring, data wiring, common electrodes, pixel electrodes, an alignment film for aligning the liquid crystal 116, etc. (none of which are shown). The main surface 114b of the TFT substrate 114, opposite to the main surface 114a, is provided with a first polarizing plate 117.
[0021] The opposing substrate 115 is located on the +Z side and faces the TFT substrate 114. The opposing substrate 115 is bonded to the TFT substrate 114 by a sealing material 119. The opposing substrate 115 is, for example, a glass substrate. The main surface 115a of the opposing substrate 115 on the liquid crystal 116 side is provided with a color filter, a black matrix, an alignment film for aligning the liquid crystal 116, etc. (none of which are shown). The main surface 115b of the opposing substrate 115, opposite to the main surface 115a, is provided with a second polarizing plate 118.
[0022] The liquid crystal 116 is sandwiched between the TFT substrate 114 and the opposing substrate 115. The liquid crystal 116 is, for example, a positive-type nematic liquid crystal. The liquid crystal 116 is initially oriented in a direction parallel to the main surface 114a of the TFT substrate 114 by an alignment film. Furthermore, when a voltage is applied, the liquid crystal 116 rotates within a plane parallel to the main surface 114a of the TFT substrate 114.
[0023] The first polarizing plate 117 is provided on the main surface 114b of the TFT substrate 114, and the second polarizing plate 118 is provided on the main surface 115b of the opposing substrate 115. One of the transmission axes, the first polarizing plate 117 and the second polarizing plate 118, is arranged parallel to the initial orientation direction of the liquid crystal 116, and the transmission axes of the first polarizing plate 117 and the second polarizing plate 118 are orthogonal. In this embodiment, the +Z side main surface 118a of the second polarizing plate 118 corresponds to the display surface 100a of the liquid crystal display panel 100.
[0024] The driver IC 122 supplies signals to the gate wiring (gate electrode of the TFT) and data wiring (source electrode of the TFT) based on signals supplied from an external source. The driver IC 122 is mounted in the bezel region 112 located on the -Y side. The driver IC 122 is connected to the outside by a flexible circuit board FL. Here, "external" refers to drive circuits, control units, devices, etc., other than the liquid crystal display panel 100.
[0025] The flexible circuit board FL of the display unit 50 is connected to the liquid crystal display panel 100 (driver IC 122), and the liquid crystal display panel 100 is connected to the outside. The flexible circuit board FL is connected to the liquid crystal display panel 100 (driver IC 122) via wiring (not shown) at the end of the frame region 112 located on the -Y side.
[0026] As shown in Figures 4 and 5, the flexible substrate FL is pulled out from the end of the frame region 112 located on the -Y side of the liquid crystal display panel 100, through the opening 332 of the housing 300, and out to the outside of the housing 300. Furthermore, as will be described later, the flexible substrate FL pulled out from the opening 332 extends to the bottom surface 322 of the housing 300 through the groove 334 of the side plate 330a of the housing 300. In this embodiment, the flexible substrate FL is fixed to the bottom surface 322 of the housing 300 by an adhesive member (not shown).
[0027] As shown in Figure 2, the backlight 200 of the display unit 50 is positioned on the back side (-Z side) of the liquid crystal display panel 100. The backlight 200 emits white light to the liquid crystal display panel 100. The backlight 200 includes a white LED (Light Emitting Diode) element, a reflective sheet, a diffusion sheet, a light guide plate, a lighting circuit, etc. (none of which are shown). The light guide plate is formed from, for example, a light-transmitting acrylic resin (PMMA: Poly Methyl Methacrylate).
[0028] The housing 300 of the display unit 50 houses the liquid crystal display panel 100 and the backlight 200. The housing 300 has a box shape, as shown in Figures 5 and 6. The housing 300 is made of resin or metal. The housing 300 has a protrusion 310 extending into the housing 300 from the side plate 330, and the liquid crystal display panel 100 is positioned on the protrusion 310. The backlight 200 is positioned on the bottom plate 320 of the housing 300.
[0029] The housing 300 has an opening 332 for pulling out the flexible substrate FL, which is connected to the liquid crystal display panel 100, to the outside of the housing 300. As shown in Figures 6 and 7, the opening 332 is formed by cutting out the upper part of the side plate 330 (hereinafter referred to as side plate 330a) located on the side from which the flexible substrate FL is pulled out. Side plate 330a corresponds to the side plate 330 of the housing 300 that has the opening 332. Side plate 330a can also be described as the side plate 330 on the side of the housing 300 where the flexible substrate FL is located.
[0030] Furthermore, a groove 334 is formed in the side plate 330a. The flexible substrate FL, which is pulled out from the opening 332 to the outside of the housing 300, extends to the bottom surface 322 of the housing 300 through the groove 334 of the side plate 330a, as shown in Figure 8. The width (length in the X direction) D1 of the opening 332 and the width D2 of the groove 334 are wider than the width D3 of the flexible substrate FL.
[0031] Returning to Figure 2, the cover 400 of the display device 10 is positioned on the display surface 100a side (+Z side) of the liquid crystal display panel 100 and protects the display unit 50. The cover 400 is formed in a flat shape from a translucent resin, glass, or the like. The outer dimensions (X direction, Y direction) of the cover 400 are larger than the outer dimensions (X direction, Y direction) of the display unit 50, as shown in Figures 1 and 2. Therefore, in a cross-sectional view, the cover 400 protrudes outward beyond the outer dimensions of the display unit 50.
[0032] The cover 400 (the main surface 400a of the cover 400 on the side facing the liquid crystal display panel 100) is bonded to the upper surface 336 of the side plate 330 of the housing 300 by an adhesive member 410, as shown in Figure 2. The adhesive member 410 is provided over the entire upper surface 336 of the side plate 330, excluding the portion forming the opening 332 (Figure 6). The adhesive member 410 is an adhesive, double-sided tape, etc. The cover 400 and the liquid crystal display panel 100 are bonded together by a light-transmitting adhesive 420 (for example, OCA: Optical Clear Adhesive).
[0033] The waterproof film 500 of the display device 10 is elastic and is formed from, for example, synthetic rubber. As shown in Figure 9, the waterproof film 500 is sheet-like and has a convex shape. The waterproof film 500 has a rectangular fixing portion 504 and a convex portion 506 protruding from the fixing portion 504. The width D4 of the fixing portion 504 is wider than the width D1 of the opening 332, the width D2 of the groove portion 334, and the width D3 of the flexible substrate FL. The width D5 of the convex portion 506 is equal to the width D1 of the opening 332.
[0034] As shown in Figure 10, the waterproof film 500 covers the gap 502 between the cover 400 and the side plate 330a of the housing 300, including the opening 332, with the flexible substrate FL passing through the opening 332 in the side plate 330a of the housing 300. Note that the gap 502 includes the opening 332, and "the gap 502 between the cover 400 and the side plate 330a of the housing 300, including the opening 332" is also referred to as the gap 502 between the cover 400 and the side plate 330a of the housing 300, or simply the gap 502.
[0035] As shown in Figures 10 and 11, the fixing portion 504 of the waterproof film 500 covers the flexible substrate FL pulled out from the opening 332 and is fixed to the side plate 330a of the housing 300, straddling the flexible substrate FL. The fixing portion 504 is fixed to the side plate 330a by an adhesive, an adhesive layer provided on the waterproof film 500, etc., which are not shown. Also, as shown in Figures 10 and 12, the protrusion 506 of the waterproof film 500 is inserted into the gap 502 between the cover 400 and the side plate 330a of the housing 300, pressing against the cover 400 and making close contact with the cover 400. The waterproof film 500 is elastic and the fixing portion 504 is fixed to the side plate 330a of the housing 300, so the protrusion 506 inserted into the gap 502 presses against the cover 400 and makes close contact with the cover 400 (the main surface 400a of the cover 400).
[0036] Since the waterproof film 500 covers the gap 502 and the protrusion 506 inserted into the gap 502 is in close contact with the cover 400, the waterproof film 500 can prevent moisture from entering the display device 10 through the gap 502. Furthermore, the width D5 of the protrusion 506 and the width D1 of the opening 332 are equal. Therefore, the waterproof film 500 can further prevent moisture from entering the display device 10 through the gap 502. Because moisture can be prevented from entering the display device 10, the display device 10 can achieve high waterproofness.
[0037] Next, the manufacturing method of the display device 10 will be described. Figure 13 is a flowchart of the manufacturing method of the display device 10. The manufacturing method of the display device 10 includes the steps of bonding the cover 400 and the liquid crystal display panel 100 to which the flexible substrate FL is connected (step S110), housing the liquid crystal display panel 100 to which the flexible substrate FL is connected in the housing 300 and bonding the cover 400 to the housing 300 (step S120), inserting the protrusion 506 of the waterproof film 500 into the gap 502 (step S130), and fixing the fixing part 504 of the waterproof film 500 to the side plate 330a of the housing 300 (step S140).
[0038] In step S110, the liquid crystal display panel 100, to which the cover 400 and the flexible circuit board FL are connected, is bonded together with adhesive 420.
[0039] In step S120, first, an adhesive member 410 is provided on the upper surface 336 of the side plate 330 of the housing 300, which houses the backlight 200, excluding the portion forming the opening 332. Next, the liquid crystal display panel 100, to which the flexible substrate FL is connected, is housed in the housing 300, and the cover 400 (main surface 400a of the cover 400) is bonded to the housing 300 (upper surface 336 of the side plate 330). The flexible substrate FL is pulled out to the outside of the housing 300 through the opening 332. Furthermore, the flexible substrate FL is routed through the groove 334 to the bottom surface 322 of the housing 300 and fixed to the bottom surface 322.
[0040] In step S130, the protrusion 506 of the waterproof film 500 is inserted into the gap 502.
[0041] In step S140, with the protrusion 506 of the waterproof film 500 inserted into the gap 502, the fixing portion 504 of the waterproof film 500 is fixed to the side plate 330a of the housing 300. For example, the adhesive layer provided on the fixing portion 504 causes the fixing portion 504 to cover the flexible substrate FL and to adhere to the side plate 330a while straddling the flexible substrate FL. Since the waterproof film 500 is elastic, fixing the fixing portion 504 to the side plate 330a causes the protrusion 506 to press against the cover 400, and the protrusion 506 adheres tightly to the cover. The waterproof film 500 also covers the gap 502 between the cover 400 and the side plate 330a of the housing 300. As a result, the display device 10 can be manufactured.
[0042] As described above, the waterproof film 500 covers the gap 502 including the opening 332, and the protrusion 506 inserted into the gap 502 is in close contact with the cover 400, so the display device 10 can achieve high waterproofness.
[0043] <Embodiment 2> In Embodiment 1, the waterproof film 500 covers the flexible substrate FL. The waterproof film 500 may cover the flexible substrate FL and be adhered to the flexible substrate FL.
[0044] The configuration of the display device 10 in this embodiment is the same as that of the display device 10 in Embodiment 1, except for the configuration of the waterproof film 500 and the flexible substrate FL. Here, the configuration of the waterproof film 500 and the flexible substrate FL will be described.
[0045] In this embodiment, the waterproof film 500 and the flexible substrate FL are bonded together. Specifically, as shown in Figure 14, the fixed portion 504 of the waterproof film 500 is bonded to the portion FLa of the flexible substrate FL that extends from the housing 300 by an adhesive member 508. The adhesive member 508 is, for example, an adhesive layer provided on the fixed portion 504 of the waterproof film 500. The other configurations of the waterproof film 500 and the flexible substrate FL in this embodiment are the same as in Embodiment 1. In this embodiment, since the waterproof film 500 and the flexible substrate FL are bonded together, it is possible to further suppress the intrusion of moisture into the display device 10 through the gap 502, and the display device 10 can achieve high waterproofness.
[0046] Next, the manufacturing method of the display device 10 of this embodiment will be described. Figure 15 is a flowchart showing the manufacturing method of the display device 10 of this embodiment. The manufacturing method of the display device 10 of this embodiment includes the steps of: bonding a liquid crystal display panel 100 to a cover 400, to which a flexible substrate FL is connected and to which a fixing portion 504 of a waterproof film 500 is bonded (step S210); housing the liquid crystal display panel 100 in the housing 300, and bonding the cover 400 to the housing 300 with the protrusion 506 of the waterproof film 500 bonded to the flexible substrate FL sandwiched in the gap 502 between the cover 400 and the side plate 330a of the housing 300 (step S220); routing the flexible substrate FL connected to the liquid crystal display panel 100 to the bottom surface 322 of the housing 300 and bonding it to the bottom surface 322 (step S230); and fixing the fixing portion 504 of the waterproof film 500 bonded to the flexible substrate FL to the side plate 330a of the housing 300 (step S240).
[0047] In step S210, the liquid crystal display panel 100, to which the flexible circuit board FL is connected, and the cover 400 are bonded together with adhesive 420. The fixing portion 504 of the waterproof film 500 is bonded to the flexible circuit board FL.
[0048] In step S220, first, an adhesive member 410 is provided on the upper surface 336 of the side plate 330 of the housing 300 that houses the backlight 200, excluding the portion forming the opening 332. Next, the liquid crystal display panel 100 to which the flexible substrate FL is connected is housed in the housing 300. At the same time as housing the liquid crystal display panel 100, the cover 400 is bonded to the housing 300 with the protrusions 506 of the waterproof film 500, which is bonded to the flexible substrate FL, sandwiched in the gap 502 between the cover 400 and the side plate 330a of the housing 300.
[0049] In step S230, the flexible circuit board FL connected to the liquid crystal display panel 100 is routed through the opening 332 and the groove 334 to the bottom surface 322 of the housing 300. Then, the flexible circuit board FL is bonded to the bottom surface 322.
[0050] In step S240, the fixing portion 504 of the waterproof film 500 covers the flexible substrate FL and, with the fixing portion 504 straddling the flexible substrate FL, is fixed to the side plate 330a. For example, the fixing portion 504 is bonded to the side plate 330a by an adhesive layer provided on the fixing portion 504. Since the waterproof film 500 is elastic, fixing the fixing portion 504 to the side plate 330a causes the protrusion 506 to press against the cover 400, and the protrusion 506 adheres tightly to the cover. The waterproof film 500 also covers the gap 502 between the cover 400 and the side plate 330a of the housing 300.
[0051] As described above, the display device 10 can be manufactured. In this embodiment, the protrusions 506 of the waterproof film 500, which is bonded to the flexible substrate FL, are sandwiched in the gap 502, and the cover 400 is bonded to the housing 300. Therefore, there is no need to insert the protrusions 506 of the waterproof film 500 into the gap 502, and the display device 10 can be easily manufactured.
[0052] As described above, in this embodiment as well, the waterproof film 500 covers the gap 502 including the opening 332, and the protrusion 506 inserted into the gap 502 is in close contact with the cover 400, so the display device 10 can achieve high waterproofness. Furthermore, the display device 10 of this embodiment can be easily manufactured.
[0053] <Embodiment 3> In Embodiment 1, the display unit 50 comprises a liquid crystal display panel 100, a flexible substrate FL, a backlight 200, and a housing 300. The display unit 50 may also include a touch panel 600.
[0054] As shown in Figure 16, the display device 10 of this embodiment comprises a display unit 50, a cover 400, a first waterproof film 520, and a second waterproof film 530. As shown in Figure 17, the display unit 50 of this embodiment comprises a liquid crystal display panel 100, a first flexible substrate FL1, a backlight 200, a housing 300, and a touch panel 600. The display unit 50 of this embodiment also comprises a second flexible substrate FL2, which will be described later.
[0055] The display unit 50 of this embodiment displays characters, images, etc., similar to the display unit 50 of Embodiment 1. Furthermore, the display unit 50 of this embodiment receives user instructions via the touch panel 600.
[0056] The configuration of the liquid crystal display panel 100, backlight 200, and housing 300 of the display unit 50 in this embodiment is the same as that of the liquid crystal display panel 100, backlight 200, and housing 300 in Embodiment 1. Furthermore, the configuration of the first flexible substrate FL1 of the display unit 50 in this embodiment is the same as that of the flexible substrate FL in Embodiment 1. Here, the touch panel 600 and the second flexible substrate FL2 will be described.
[0057] The touch panel 600 is a capacitive touch panel. As shown in Figure 18, the touch panel 600 has a translucent substrate 610, a plurality of first electrodes 620, an insulating layer 630, and a plurality of second electrodes 640.
[0058] The translucent substrate 610 is, for example, a glass substrate. The translucent substrate 610 has a first main surface 610a located on the +Z side. The translucent substrate 610 also has a detection area 611 and a frame area 612 surrounding the detection area 611. The detection area 611 corresponds to the display area 111 of the liquid crystal display panel 100.
[0059] Each first electrode 620 is provided on the first main surface 610a of the translucent substrate 610. The first electrodes 620 extend in the X direction. The first electrodes 620 are also arranged at equal intervals in the Y direction. The first electrodes 620 have a pattern (a so-called diamond pattern) in which the corners of multiple squares are connected in a row. Each of the first electrodes 620 is connected to the second flexible substrate FL2 via wiring (not shown).
[0060] The insulating layer 630 is provided on the first electrode 620 to insulate the first electrode 620 from the second electrode 640. The insulating layer 630 is, for example, a silicon oxide thin film.
[0061] Each second electrode 640 is provided on top of the insulating layer 630. The second electrodes 640 extend in the Y direction. Like the first electrodes 620, the second electrodes 640 have a pattern in which multiple square corners are connected in a row. Each of the second electrodes 640 is connected to the second flexible substrate FL2 via wiring (not shown).
[0062] The first electrode 620 and the second electrode 640 are formed from, for example, ITO (Indium Tin Oxide). When the touch panel 600 is viewed from above, the first electrode 620 and the second electrode 640 intersect at the connection point that connects the corners of the rectangle. The first electrode 620 and the second electrode 640 form capacitance with the object (for example, the user's finger, hand, pen, etc.).
[0063] When viewed from above, the external shape (X direction, Y direction) of the touch panel 600 (translucent substrate 610) is the same as the external shape of the housing 300. As shown in Figure 17, the touch panel 600 is positioned on the display surface 100a side (+Z side) of the liquid crystal display panel 100, and the second main surface 610b of the translucent substrate 610, opposite to the first main surface 610a, is bonded to the upper surface 336 of the side plate 330 of the housing 300 by an adhesive member 660. The adhesive member 660 is provided on the entire upper surface 336 of the side plate 330, except for the portion forming the opening 332, similar to the adhesive member 410 in Embodiment 1. In addition, a translucent adhesive 662 is filled between the touch panel 600 and the liquid crystal display panel 100. The second main surface 610b of the translucent substrate 610, opposite to the first main surface 610a, corresponds to the main surface of the touch panel 600 on the liquid crystal display panel 100 side.
[0064] The second flexible substrate FL2 connects to the first electrode 620 and the second electrode 640 of the touch panel 600, thereby connecting the touch panel 600 to the outside. As shown in Figure 18, the second flexible substrate FL2 is connected to the touch panel 600 (first electrode 620 and second electrode 640) via wiring (not shown) at the end of the frame region 612 located on the +X side.
[0065] As shown in Figure 19, the second flexible substrate FL2 extends from the edge of the frame region 612 located on the +X side of the touch panel 600, along the side plate 330 (hereinafter referred to as side plate 330b) on the +X side of the housing 300, and further extends to the bottom surface 322 of the housing 300. In this embodiment, the second flexible substrate FL2 is fixed to the bottom surface 322 of the housing 300 by an adhesive member (not shown). Side plate 330b corresponds to the side plate 330 on the side of the housing 300 where the second flexible substrate FL2 is located.
[0066] Returning to Figure 17, the cover 400 in this embodiment is positioned on the display surface 100a side (+Z side) of the liquid crystal display panel 100 and covers the touch panel 600. The cover 400 in this embodiment is bonded to the touch panel 600 with a light-transmitting adhesive 430. Specifically, the main surface 400a of the cover 400 on the liquid crystal display panel side and the touch panel 600 are bonded together. In this embodiment, the second flexible substrate FL2 and the peripheral portion of the second flexible substrate FL2 in the frame area 612 of the touch panel 600 are not bonded to the main surface 400a of the cover 400. Also, the portion of the main surface 400a of the cover 400 that is in close contact with the first waterproof film 520 is not bonded to the touch panel 600.
[0067] In this embodiment, the second flexible substrate FL2 and the area around the second flexible substrate FL2 in the frame region 612 of the touch panel 600 are not bonded to the cover 400. As shown in Figure 19, a gap 532 is created between the cover 400 and the frame region 612 to which the second flexible substrate FL2 of the touch panel 600 is connected. The other configurations of the cover 400 in this embodiment are the same as those of the cover 400 in Embodiment 1.
[0068] The first waterproof film 520 of the display device 10 in this embodiment is sheet-like and has a convex shape, similar to the waterproof film 500 of Embodiment 1. As shown in Figure 20, the first waterproof film 520 has a rectangular first fixing portion 524 and a first convex portion 526 protruding from the first fixing portion 524. The first waterproof film 520 is elastic and is formed from, for example, synthetic rubber.
[0069] Similar to the waterproof film 500 of Embodiment 1, the first waterproof film 520 covers the gap 522 between the cover 400 and the side plate 330a of the housing 300, with the first flexible substrate FL1 passing through the opening 332 of the side plate 330a of the housing 300. As shown in Figures 17 and 21, the first fixing portion 524 of the first waterproof film 520 covers the first flexible substrate FL1 pulled out from the opening 332 and is fixed to the side plate 330a of the housing 300, straddling the first flexible substrate FL1. In addition, the first protrusion 526 of the first waterproof film 520 is inserted into the gap 502 between the cover 400 and the side plate 330a of the housing 300, pressing against the cover 400 and making close contact with it. Therefore, similar to the waterproof film 500 of Embodiment 1, the first waterproof film 520 can prevent moisture from entering the display device 10 through the gap 522. The other components of the first waterproof film 520 are the same as those of the waterproof film 500 in Embodiment 1.
[0070] The second waterproof film 530 of the display device 10 in this embodiment, like the first waterproof film 520, is sheet-like and has a convex shape. As shown in Figure 22, the second waterproof film 530 has a rectangular second fixing portion 534 and a second convex portion 536 protruding from the second fixing portion 534. The second waterproof film 530 is also elastic and is formed from, for example, synthetic rubber.
[0071] As shown in Figures 19 and 23, the second waterproof film 530 covers the gap 532 between the cover 400 and the frame region 612 connecting the second flexible substrate FL2 of the touch panel 600. The second fixing portion 534 of the second waterproof film 530 covers the second flexible substrate FL2 extending along the side plate 330b of the housing 300 and is fixed to the side plate 330b across the second flexible substrate FL2. The second fixing portion 534 is fixed to the side plate 330b by an adhesive, an adhesive layer provided on the waterproof film 500, etc. (not shown). In addition, the second protrusion 536 of the second waterproof film 530 is inserted into the gap 532, pressing against the cover 400 and making close contact with the cover 400. The second waterproof film 530 is elastic, and the second fixing portion 534 is fixed to the side plate 330b of the housing 300. Therefore, the second protrusion 536 inserted into the gap 532 presses against the cover 400 and adheres tightly to the cover 400 (the main surface 400a of the cover 400).
[0072] The second waterproof film 530 covers the gap 532, and the second protrusion 536 inserted into the gap 532 is in close contact with the cover 400. Therefore, similar to the waterproof film 500 of Embodiment 1, the second waterproof film 530 can prevent moisture from entering the display device 10 through the gap 532.
[0073] As shown in Figure 23, the width (length in the Y direction) D6 of the second protrusion 536 of the second waterproof film 530 is equal to the width D7 of the gap 532. Also, the width D7 of the gap 532 is wider than the width D8 of the second flexible substrate FL2. The width D9 of the second fixing portion 534 of the second waterproof film 530 is wider than the width D8 of the second flexible substrate FL2.
[0074] As described above, the first waterproof film 520 suppresses the intrusion of moisture through the gap 522, and the second waterproof film 530 suppresses the intrusion of moisture through the gap 532, so the display device 10 of this embodiment can also achieve high waterproofness.
[0075] <Embodiment 4> In Embodiment 3, the first waterproof film 520 covers the gap 522 between the cover 400 and the side plate 330a of the housing 300, with the first flexible substrate FL1 passing through the opening 332 of the side plate 330a of the housing 300. The first waterproof film 520 may also cover the gap 528 between the touch panel 600 and the side plate 330a of the housing 300, with the first flexible substrate FL1 passing through the opening 332 of the side plate 330a of the housing 300.
[0076] The configuration of the display device 10 in this embodiment is the same as that of the display device 10 in Embodiment 3, except for the first waterproof film 520. Here, the first waterproof film 520 of this embodiment will be described.
[0077] The first waterproof film 520 of this embodiment, like the first waterproof film 520 of Embodiment 3, has a rectangular first fixing portion 524 and a first protrusion 526 protruding from the first fixing portion 524. The first waterproof film 520 of this embodiment is also elastic and is formed from, for example, synthetic rubber.
[0078] As shown in Figures 24 and 25, the first waterproof film 520 of this embodiment covers the gap 528 between the touch panel 600 and the side plate 330a of the housing 300, including the opening 332, with the first flexible substrate FL1 passing through the opening 332 in the side plate 330a of the housing 300. The gap 528 includes the opening 332, similar to the gap 522 in Embodiment 1.
[0079] As shown in Figures 24 and 25, the first fixing portion 524 of the first waterproof film 520 of this embodiment covers the first flexible substrate FL1 pulled out from the opening 332 and is fixed to the side plate 330a of the housing 300, straddling the first flexible substrate FL1. In addition, the first protrusion 526 of the first waterproof film 520 is inserted into the gap 528 between the touch panel 600 and the side plate 330a of the housing 300, including the opening 332, and presses against the touch panel 600, making it adhere to the touch panel 600. Therefore, the first waterproof film 520 of this embodiment, like the waterproof film 500 of Embodiment 1, can prevent moisture from entering the display device 10 through the gap 522. The other configurations of the first waterproof film 520 of this embodiment are the same as those of the first waterproof film 520 of Embodiment 3.
[0080] As described above, the first waterproof film 520 of this embodiment can suppress the intrusion of moisture through the gap 528. Furthermore, the second waterproof film 530, similar to Embodiment 3, can suppress the intrusion of moisture through the gap 532. Therefore, the display device 10 of this embodiment can also achieve high waterproofness.
[0081] <Variation> While embodiments have been described above, this disclosure can be modified in various ways without departing from its essence.
[0082] The display unit 50 includes a display panel for displaying characters, images, etc., and the flexible circuit board FL or the first flexible circuit board FL1 only needs to be connected to the display panel.
[0083] For example, the display unit 50 may include an OLED (Electro-Luminescence) display panel 700, as shown in Figure 26. In the example shown in Figure 26, the flexible substrate FL is connected to the OLED display panel 700 (driver IC 122), and the OLED display panel 700 is connected externally. The housing 300 also houses the OLED display panel 700.
[0084] In this embodiment, the cover 400 protects the display unit 50. The cover 400 may also be a component that provides design to the user.
[0085] In this embodiment, the flexible substrate FL, the first flexible substrate FL1, and the second flexible substrate FL2 are fixed to the bottom surface 322 of the housing 300. The flexible substrate FL, the first flexible substrate FL1, and the second flexible substrate FL2 do not necessarily have to be fixed to the bottom surface 322 of the housing 300.
[0086] In this embodiment, the width D5 of the protrusion 506 of the waterproof film 500 and the width D5 of the first protrusion 526 of the first waterproof film 520 are equal to the width D1 of the opening 332. The widths D5 of the protrusions 506 and the first protrusion 526 and the width D1 of the opening 332 do not have to be equal. The widths D5 of the protrusions 506 and the first protrusion 526 and the width D1 of the opening 332 may be approximately equal.
[0087] In this embodiment, the width D6 of the second protrusion 536 of the second waterproof film 530 is equal to the width D7 of the gap 532. The width D6 of the second protrusion 536 and the width D7 of the gap 532 do not have to be equal. The width D6 of the second protrusion 536 and the width D7 of the gap 532 may be approximately equal.
[0088] The fixing portion 504 of the waterproof film 500 may extend to the bottom surface 322 of the housing 300, as shown in Figure 27, and cover the flexible substrate FL on the bottom surface 322. Furthermore, the fixing portion 504 may be fixed to the bottom surface 322, straddling the flexible substrate FL.
[0089] The first fixing portion 524 of the first waterproof film 520 may also extend to the bottom surface 322 of the housing 300, covering the first flexible substrate FL1 at the bottom surface 322. The first fixing portion 524 may also be fixed to the bottom surface 322, straddling the first flexible substrate FL1.
[0090] The second fixing portion 534 of the second waterproof film 530 may also extend to the bottom surface 322 of the housing 300 and cover the second flexible substrate FL2 on the bottom surface 322. The second fixing portion 534 may be fixed to the bottom surface 322 across the second flexible substrate FL2.
[0091] When the fixing portion 504 of the waterproof film 500 is adhered to the flexible substrate FL by the adhesive member 508, as shown in FIG. 28, the length L1 of the end portion 501 on the side inserted into the gap 502 of the waterproof film 500 is preferably shorter than the length L2 of the end portion F1 on the side connected to the liquid crystal display panel 100 of the flexible substrate FL (L1 < L2). When the length L1 of the end portion 501 of the waterproof film 500 is longer than the length L2 of the end portion F1 of the flexible substrate FL, the convex portion 506 of the waterproof film 500 enters deep into the gap 502, and the convex portion 506 of the waterproof film 500 presses the cover 400 in the vicinity of the liquid crystal display panel 100, so there is a risk of display unevenness occurring in the display device 10. Here, the end portion 501 on the side inserted into the gap 502 of the waterproof film 500 is a portion of the waterproof film 500 that is not adhered to the flexible substrate FL including the convex portion 506, and the length L1 of the end portion 501 is from the end face (end face of the convex portion 506) 501a on the side inserted into the gap 502 of the waterproof film 500 to the end 501b on the side inserted into the gap 502 of the portion of the waterproof film 500 adhered to the flexible substrate FL. Also, the end portion F1 on the side connected to the liquid crystal display panel 100 of the flexible substrate FL is a portion that is not adhered to the waterproof film 500 on the side connected to the liquid crystal display panel 100, and the length L2 of the end portion F1 is from the end face Fa on the side connected to the liquid crystal display panel 100 of the flexible substrate FL to the end Fb on the side connected to the liquid crystal display panel 100 of the portion of the flexible substrate FL adhered to the waterproof film 500.
[0092] Also, when the fixing portion 504 of the waterproof film 500 is adhered to the flexible substrate FL by the adhesive member 508, the length L1 of the end portion 501 on the side inserted into the gap 502 of the waterproof film 500 is preferably longer than the distance L3 (distance in the Z direction) between the main surface 400a of the cover 400 and the end surface 508b of the adhesive member 508 on the cover 400 side (L3 < L1). Thereby, the waterproof film 500 closes the gap 502 and can sufficiently press the cover 400.
[0093] The first fixing portion 524 of the first waterproof film 520 may be adhered to the first flexible substrate FL1. Also, the second fixing portion 534 of the second waterproof film 530 may be adhered to the second flexible substrate FL2.
[0094] When the first fixing portion 524 of the first waterproof film 520 is adhered to the first flexible substrate FL1, similar to the case where the fixing portion 504 of the waterproof film 500 is adhered to the flexible substrate FL, the length of the end portion on the side inserted into the gap 522 or gap 528 of the first waterproof film 520 is preferably shorter than the length of the end portion on the side connected to the liquid crystal display panel 100 of the first flexible substrate FL1. Also, when the second fixing portion 534 of the second waterproof film 530 is adhered to the second flexible substrate FL2, similar to the case where the fixing portion 504 of the waterproof film 500 is adhered to the flexible substrate FL, the length of the end portion on the side inserted into the gap 532 of the second waterproof film 530 is preferably shorter than the length of the end portion on the side connected to the touch panel 600 of the second flexible substrate FL2.
[0095] When the first fixing portion 524 of the first waterproof film 520 is bonded to the first flexible substrate FL1, and the first waterproof film 520 covers the gap 522 between the cover 400 and the side plate 330a of the housing 300, it is preferable that the length of the end of the first waterproof film 520 that is inserted into the gap 522 is longer than the distance between the main surface 400a of the cover 400 and the end face on the cover 400 side of the adhesive member that bonds the first waterproof film 520 and the first flexible substrate FL1. Furthermore, when the first fixing portion 524 of the first waterproof film 520 is bonded to the first flexible substrate FL1 and the first waterproof film 520 covers the gap 528 between the touch panel 600 and the side plate 330a of the housing 300, it is preferable that the length of the end of the first waterproof film 520 that is inserted into the gap 528 is longer than the distance between the touch panel 600 (the second main surface 610b of the translucent substrate 610) and the end face on the cover 400 side of the adhesive member that bonds the first waterproof film 520 and the first flexible substrate FL1. When the second fixing portion 534 of the second waterproof film 530 is bonded to the second flexible substrate FL2, it is preferable that the length of the end of the second waterproof film 530 that is inserted into the gap 532 is longer than the distance between the touch panel 600 and the end face on the cover 400 side of the adhesive member that bonds the second waterproof film 530 and the second flexible substrate FL2.
