Description

表示装置Display device
　本発明は、保護板やタッチパネル等を備える表示装置に関する。 The present invention relates to a display device including a protective plate, a touch panel, and the like.
　表示部の表示面を衝撃や汚れ等から保護するために透明部材等を用いた保護板を、表示部の表示面側に設置した表示装置がある。また、タッチパネルを表示部の表示面側に設置した表示装置がある。 There is a display device in which a protective plate using a transparent member or the like is installed on the display surface side of the display unit in order to protect the display surface of the display unit from impact or dirt. There is also a display device in which a touch panel is installed on the display surface side of the display unit.
　このような表示装置では、一般に、表示部の表示面の周辺に配置されたシール材により、保護板やタッチパネルを表示部の表示面側に接着し、固定する。 In such a display device, in general, a protective plate and a touch panel are adhered and fixed to the display surface side of the display unit by a sealing material disposed around the display surface of the display unit.
　図８は、従来の表示装置９００における、表示部９１、シール材９２、および、保護板９３の概略構成を示す図である。また、図９は、表示装置９００の表示部９１およびシール材９２の位置関係を示す平面図である。 FIG. 8 is a diagram showing a schematic configuration of the display unit 91, the sealing material 92, and the protective plate 93 in the conventional display device 900. FIG. 9 is a plan view showing the positional relationship between the display unit 91 and the sealing material 92 of the display device 900.
　例えば、特許文献１に開示されている表示装置では、図８、９に示すように、シール材９２は、表示部９１の表示面９１１を囲むように配置され、かつ、シール材９２が囲む内部の領域と外部の領域とが一部で繋がるように通気口９４１および９４２が形成されるように配置される。 For example, in the display device disclosed in Patent Document 1, as shown in FIGS. 8 and 9, the sealing material 92 is disposed so as to surround the display surface 911 of the display unit 91, and the inside surrounded by the sealing material 92. The vents 941 and 942 are arranged so that the region and the external region are partially connected.
　このようにシール材９２を配置し、表示部９１と保護板９３とを接着し固定することで、結露を防止するとともに、外部から異物が混入されることを防止する。つまり、上記のようにシール材９２を配置することで、通気口９４１および９４２により通気が確保されるので、表示面９１１と保護板９３との間の空間に水蒸気が残留しにくく、温度が急激に上昇した場合であっても、表示部９１と保護板９３との間において、結露が生じにくい。また、上記のようにシール材９２を配置することで、シール材９２で囲まれた表示面９１１と保護板９３との間の空間の内側と外側とを接続する経路は、通気口９４１および９４２だけとなるので、異物が表示面９１１と保護板９３との間の空間に外部から進入することを防ぐことができる。 The seal material 92 is arranged in this way, and the display unit 91 and the protective plate 93 are bonded and fixed, thereby preventing condensation and preventing foreign matters from being mixed in from the outside. That is, by arranging the sealing material 92 as described above, ventilation is ensured by the vents 941 and 942, so that water vapor hardly remains in the space between the display surface 911 and the protective plate 93, and the temperature rapidly increases. Even when the temperature rises, condensation is unlikely to occur between the display portion 91 and the protective plate 93. Further, by arranging the sealing material 92 as described above, the paths connecting the inner side and the outer side of the space between the display surface 911 surrounded by the sealing material 92 and the protective plate 93 are vent holes 941 and 942. Therefore, foreign matter can be prevented from entering the space between the display surface 911 and the protective plate 93 from the outside.

　しかしながら、特許文献１に開示されている表示装置では、図９に示すように、表示部９１と保護板９３と間の空間と表示装置の外部の空間とが、細い幅の経路である通気口９４１および９４２により接続されているだけであるので、例えば、表示部９１と保護板９３とを接着し固定する際に、異物が表示部９１と保護板９３と間の空間に入ると、当該異物を表示装置の外に排除することが困難である。特に、特許文献１に開示されている表示装置では、表示部９１と保護板９３とを接着し固定した後において、表示部９１と保護板９３と間の空間に入った異物を排除することは困難である。 However, in the display device disclosed in Patent Document 1, as shown in FIG. 9, the space between the display unit 91 and the protective plate 93 and the space outside the display device are narrow passages. 941 and 942 are connected to each other. For example, when the foreign substance enters the space between the display unit 91 and the protective plate 93 when the display unit 91 and the protective plate 93 are bonded and fixed, Is difficult to exclude outside the display device. In particular, in the display device disclosed in Patent Document 1, after the display unit 91 and the protective plate 93 are bonded and fixed, it is possible to eliminate foreign matter that has entered the space between the display unit 91 and the protective plate 93. Have difficulty.
　そこで、本発明は、上記課題に鑑み、保護板やタッチパネル等と表示部の表示面との間の空間に混入した異物を容易に排出させることができ、かつ、異物が表示面に滞留することによる表示面の表示品質劣化を効果的に防止することができる表示装置を実現することを目的とする。 Therefore, in view of the above problems, the present invention can easily discharge foreign matters mixed in the space between the protective plate, the touch panel, etc. and the display surface of the display unit, and the foreign matters can stay on the display surface. An object of the present invention is to realize a display device that can effectively prevent display quality deterioration of the display surface due to the above.
　上記課題を解決するために、第１の構成の表示装置は、表示部と、保護部と、シール材と、を備える。 In order to solve the above-described problem, the display device having the first configuration includes a display unit, a protection unit, and a sealing material.
　表示部は、表示面を有する。保護部は、表示面を覆うように配置される。シール材は、表示部と保護部との間に設けられ、第１シール材と第１シール材より厚みの厚い第２シール材とを含む。 The display unit has a display surface. The protection unit is disposed so as to cover the display surface. The sealing material is provided between the display unit and the protection unit, and includes a first sealing material and a second sealing material that is thicker than the first sealing material.

That is, a space between the first sealing material 21a and the protection plate 3 and a space between the first sealing material 21b and the protection plate 3 are ensured so that the foreign matter or the like can be efficiently discharged. In addition, the shape and arrangement of the first sealing materials 21a and 21b and the second sealing materials 22a to 22f may be determined.
　以上のように、表示装置１０００では、第１シール材２１ａ、２１ｂの厚みが、第２シール材２２ａ～２２ｆの厚みよりも薄いので、表示部１と保護板３とを第２シール材２２ａ～２２ｆにより固定した状態において、第１シール材２１ａと保護板３との間、および、第１シール材２１ｂと保護板３との間に空間が形成される。これにより、表示装置１０００では、第１シール材２１ａ、２１ｂと保護板との間に形成される空間（間隙）を通して、表示部１と保護板３との間に混入された異物等を表示装置１０００の外部に効率良く排出することができる。つまり、図２、図３に示すように、表示装置１０００、１０００Ａでは、第１シール材２１ａ、２１ｂが、平面視で、表示面１１を挟んで対向する位置に配置されるので、例えば、第１シール材２１ａと保護板３との間の空間から、第１シール材２１ｂと保護板３との間の空間へ向かって、エアー（空気）を吹き付けることで、表示部１と保護板３との間の空間に混入された異物等を、効率良く、表示装置１０００の外部に排出することができる。さらに、第１シール材２１ａ、２１ｂの保護板３側の面が糊面であるので、例えば、第１シール材２１ａと保護板３との間の空間から、第１シール材２１ｂと保護板３との間の空間へ向かって、エアー（空気）を吹き付けることで、表示部１と保護板３との間の空間に混入された異物等を、第１シール材２１ａ、２１ｂの保護板３側の面に固着させることもできる。これにより、当該異物等が、再度、表示部１と保護板３との間に混入されることを防止できる。 As described above, in the display device 1000, the thickness of the first seal materials 21a and 21b is thinner than the thickness of the second seal materials 22a to 22f, so that the display unit 1 and the protection plate 3 are connected to the second seal materials 22a to 22f. In the state fixed by 22f, spaces are formed between the first sealing material 21a and the protective plate 3 and between the first sealing material 21b and the protective plate 3. Thereby, in the display device 1000, foreign matter mixed between the display unit 1 and the protective plate 3 through the space (gap) formed between the first sealing materials 21a and 21b and the protective plate is displayed on the display device 1000. 1000 can be efficiently discharged to the outside. That is, as shown in FIGS. 2 and 3, in the display devices 1000 and 1000A, the first sealing materials 21a and 21b are arranged at positions facing each other across the display surface 11 in plan view. By blowing air (air) from the space between the 1 seal material 21a and the protection plate 3 toward the space between the first seal material 21b and the protection plate 3, the display unit 1 and the protection plate 3 Foreign matter or the like mixed in the space between can be efficiently discharged to the outside of the display device 1000. Furthermore, since the surface of the first sealing material 21a, 21b on the protective plate 3 side is a glue surface, for example, from the space between the first sealing material 21a and the protective plate 3, the first sealing material 21b and the protective plate 3 are used. By blowing air (air) toward the space between the first sealing material 21a and the protection plate 3 side of the first sealing material 21b, foreign matter mixed in the space between the protection plate 3 and the like It can also be fixed to the surface. Thereby, the said foreign material etc. can prevent mixing between the display part 1 and the protection board 3 again.
　このように、表示装置１０００では、表示部１と保護板３とを接着し固定した後においても、表示部１と保護板３と間の空間に入った異物を効率良く排出することができる。また、表示装置１０００では、第１シール材２１ａ、２１ｂの糊面（保護板３側の面）に異物等を固着することで、異物等が、再度表示面１１上に混入されることを防止する。したがって、表示装置１０００では、保護板３と表示部１の表示面１１との間の空間に混入した異物を容易に排出させることができ、かつ、異物等が表示面１１に滞留することによる表示面１１の表示品質劣化を効果的に防止することができる。さらに、表示装置１０００では、厚みの異なる２種類のシール材を用いて構成されるので、製造が容易である。 As described above, in the display device 1000, even after the display unit 1 and the protective plate 3 are bonded and fixed, the foreign matter that has entered the space between the display unit 1 and the protective plate 3 can be efficiently discharged. Further, in the display device 1000, foreign matters are prevented from being mixed on the display surface 11 again by fixing the foreign matters etc. to the glue surfaces (surfaces on the protective plate 3 side) of the first sealing materials 21a, 21b. To do. Therefore, in the display device 1000, foreign matter mixed in the space between the protective plate 3 and the display surface 11 of the display unit 1 can be easily discharged, and the display by the foreign matter staying on the display surface 11 is possible. The display quality deterioration of the surface 11 can be effectively prevented. Furthermore, since the display device 1000 is configured using two types of sealing materials having different thicknesses, it is easy to manufacture.

　表示装置３０００では、上記のように構成されることにより、表示部１と保護板３とを第２シール材２２１ａ、２２ｃ、２２１ｅおよび２２ｆにより固定した状態において、第１シール材２１１ａと保護板３との間、および、第１シール材２１１ｂと保護板３との間に空間が形成される。これにより、表示装置３０００では、第１シール材２１１ａと保護板との間、および、第１シール材２１１ｂと保護板との間に形成される空間（間隙）を通して、表示部１と保護板３との間に混入された異物等を表示装置２０００の外部に効率良く排出することができる。つまり、図５に示すように、表示装置３０００では、第１シール材２１１ａ、２１１ｂが、平面視で、表示面１１を挟んで対向する位置に配置される。したがって、表示装置３０００では、第１シール材２１１ａと保護板３との間の空間から、第１シール材２１１ｂと保護板３との間の空間へ向かう経路にエアー（空気）を吹き付けることで、表示部１と保護板３との間の空間に混入された異物等を、さらに効率良く、表示装置３０００の外部に排出することができる。さらに、第１シール材２１１ａ、２１１ｂの保護板３側の面が糊面であるので、上記経路を使ってエアー（空気）を吹き付けることで、表示部１と保護板３との間の空間に混入された異物等を、第１シール材２１１ａ、２２１ｂの保護板３側の面（糊面）に固着させることもできる。これにより、当該異物等が、再度、表示部１と保護板３との間に混入されることを防止できる。 The display device 3000 is configured as described above, so that the first sealing material 211a and the protective plate 3 are fixed in a state where the display unit 1 and the protective plate 3 are fixed by the second sealing materials 221a, 22c, 221e, and 22f. And a space is formed between the first sealing material 211b and the protective plate 3. Accordingly, in the display device 3000, the display unit 1 and the protection plate 3 are passed through the space (gap) formed between the first seal material 211a and the protection plate and between the first seal material 211b and the protection plate. Can be efficiently discharged to the outside of the display device 2000. That is, as shown in FIG. 5, in the display device 3000, the first sealing materials 211 a and 211 b are arranged at positions facing each other across the display surface 11 in plan view. Therefore, in the display device 3000, by blowing air (air) from the space between the first sealing material 211a and the protection plate 3 to the path toward the space between the first sealing material 211b and the protection plate 3, Foreign matter or the like mixed in the space between the display unit 1 and the protection plate 3 can be discharged to the outside of the display device 3000 more efficiently. Furthermore, since the surface of the first sealing material 211a, 211b on the protective plate 3 side is a glue surface, air is blown into the space between the display unit 1 and the protective plate 3 using the above path. The mixed foreign matter or the like can be fixed to the surface (glue surface) of the first sealing material 211a, 221b on the protective plate 3 side. Thereby, the said foreign material etc. can prevent mixing between the display part 1 and the protection board 3 again.
　このように、表示装置３０００では、表示部１と保護板３とを接着し固定した後においても、表示部１と保護板３と間の空間に入った異物を効率良く排出することができる。また、表示装置３０００では、第１シール材２１１ａ、２１１ｂの糊面（保護板３側の面）に異物等を固着することで、異物等が、再度表示面１１上に混入されることを防止する。したがって、表示装置３０００では、保護板３と表示部１の表示面１１との間の空間に混入した異物を容易に排出させることができ、かつ、異物等が表示面１１に滞留することによる表示面１１の表示品質劣化を効果的に防止することができる。 As described above, in the display device 3000, even after the display unit 1 and the protection plate 3 are bonded and fixed, the foreign matter that has entered the space between the display unit 1 and the protection plate 3 can be efficiently discharged. Further, in the display device 3000, the foreign matter and the like are prevented from being mixed on the display surface 11 again by fixing the foreign matter and the like to the glue surface (the surface on the protective plate 3 side) of the first sealing materials 211a and 211b. To do. Therefore, in the display device 3000, the foreign matter mixed in the space between the protective plate 3 and the display surface 11 of the display unit 1 can be easily discharged, and the display by the foreign matter remaining on the display surface 11 is possible. The display quality deterioration of the surface 11 can be effectively prevented.
