As shown in Patent Document 1, the shield plate is attached to the substrate. However, in order to reduce the size of the substrate, it is considered that the shield plate is attached to the holder of the LCD. 5 and 6 show examples of the conventional structure of the display device in which the shield plate is fitted and fixed to the holder or the holder and the substrate.

図５、図６に示す構造は、基板１０１、ホルダ１０２、ＬＣＤ１０３、シールド板金１０４からなるもので、基板１０１上にホルダ１０２を設け、その上にＬＣＤ１０３を置き、その上からフレーム状のシールド板金１０４を被せる構造となっている。ＬＣＤ１０３に対しては光源と拡散板が設けられるが、図示は省略している。   5 and 6 includes a substrate 101, a holder 102, an LCD 103, and a shield sheet metal 104. The holder 102 is provided on the substrate 101, the LCD 103 is placed thereon, and a frame-shaped shield sheet metal is formed thereon. 104 is covered. The LCD 103 is provided with a light source and a diffusion plate, which are not shown.

ホルダ１０２の長手方向の両側面には嵌合突起１０２ａが３箇所ずつ設けられている。嵌合突起１０２ａ間は凹所１０２ｂとなっている。シールド板金１０４には、嵌合突起１０２ａに嵌合される嵌合穴１０４ａが、嵌合突起１０２ａと同じ位置に設けられている。シールド板金１０４の端尺の側面の底部には、基板１０１に取り付けるための取り付け部１０４ｂが設けられている。ＬＣＤ１０３には端子１０３ａが設けられているが、これらの端子１０３ａはホルダ１０２の凹所１０２ｂに合わせた位置に設けられている。   Three fitting projections 102 a are provided on both side surfaces in the longitudinal direction of the holder 102. A recess 102b is formed between the fitting protrusions 102a. The shield metal plate 104 is provided with a fitting hole 104a to be fitted into the fitting protrusion 102a at the same position as the fitting protrusion 102a. An attachment portion 104 b for attachment to the substrate 101 is provided at the bottom of the side surface of the end plate of the shield metal plate 104. The LCD 103 is provided with terminals 103 a, and these terminals 103 a are provided at positions corresponding to the recesses 102 b of the holder 102.

この図５に示す構造の表示装置にあっては、基板１０１にホルダ１０２を置き、その上にＬＣＤ１０３を載せると共に、その端子１０３ａをホルダ１０２の凹所１０２ｂを沿わせて基板１０１の穴１０１ａに通し、更にその上にシールド板金１０４を被せ、その嵌合穴１０４ａをホルダ１０２の嵌合突起１０２ａに嵌合させると共に、取り付け部１０４ｂを基板１０１側に取り付けることにより組み立てられる。   In the display device having the structure shown in FIG. 5, the holder 102 is placed on the substrate 101, the LCD 103 is placed thereon, and the terminal 103 a is placed in the hole 101 a of the substrate 101 along the recess 102 b of the holder 102.

しかし、図５、図６に示した構造のものでは、ホルダ１０２の側面の嵌合部１０２ａに対応する箇所には端子１０３ａを設けることができないことから、ＬＣＤ１０３における端子１０３ａの配置が分断され、表示装置自体がカスタム仕様となってしまい、コストが嵩んでしまう。また、シールド板金１０４とホルダ１０２との嵌合部以外の部分では、端子１０３ａとシールド板金１０４との間にそれぞれの位置を規制する構造はなく、端子１０３ａとシールド板金１０４とが接触しショートするおそれがあった。   However, in the structure shown in FIGS. 5 and 6, since the terminal 103 a cannot be provided at a position corresponding to the fitting portion 102 a on the side surface of the holder 102, the arrangement of the terminal 103 a in the LCD 103 is divided, The display device itself becomes a custom specification, and the cost increases. Further, in a portion other than the fitting portion between the shield sheet metal 104 and the holder 102, there is no structure for restricting the position between the terminal 103a and the shield sheet metal 104, and the terminal 103a and the shield sheet metal 104 come into contact with each other and short-circuit. There was a fear.

この発明は、このような状況にかんがみてなされたもので、規格化されたＬＣＤを使用することができ、しかも端子とシールド板金とのショートを生ずることのない表示装置を提供することを目的とする。   The present invention has been made in view of such a situation, and an object thereof is to provide a display device that can use a standardized LCD and that does not cause a short circuit between a terminal and a shield metal plate. To do.

この発明に係る表示装置は、基板上にホルダを設け、このホルダの上に、側面に端子を有するＬＣＤを設け、このＬＣＤにシールド板金を設けてなる表示装置において、前記ホルダの側面に一方の嵌合部を設け、前記シールド板金に前記一方の嵌合部に嵌合する他方の嵌合部を設け、前記ホルダの側面における前記一方の嵌合部より内側に、前記端子を案内する案内部を設け、この案内部の側面に、前記シールド板金の側壁が当接するようにしたものである。   A display device according to the present invention is a display device in which a holder is provided on a substrate, an LCD having a terminal on a side surface is provided on the holder, and a shield sheet metal is provided on the LCD. A guide portion for providing a fitting portion, providing the other fitting portion to be fitted to the one fitting portion on the shield sheet metal, and guiding the terminal inside the one fitting portion on a side surface of the holder. The side wall of the shield sheet metal comes into contact with the side surface of the guide portion.

この発明に係る表示装置によれば、ホルダの側面に、ＬＣＤの端子を案内する案内部を設けてあるので、ＬＣＤの端子を分断する必要がなく、ＬＣＤをカスタマイズする必要がなくなるのでコストの削減となる。また、案内部がシールド板金に当接しその位置を規制するので、シールド板金と端子のショートを防ぐことができる。   According to the display device of the present invention, since the guide portion for guiding the LCD terminal is provided on the side surface of the holder, it is not necessary to divide the LCD terminal and there is no need to customize the LCD, thereby reducing the cost. It becomes. Moreover, since the guide part abuts on the shield metal plate and restricts its position, it is possible to prevent a short circuit between the shield metal plate and the terminal.
