ことが望まれ、る。In a display device that displays numbers and figures by arranging a large number of LBDs in a matrix and sending selective electrical signals to the LIPIDs, it is necessary to devise a connection method and structure between the LBDs and wiring bodies. The most common conventional connection method is to use an insulating substrate provided with a cando wiring body and an anode wiring body, first fix the LBD pellet on the cathode wiring body with conductive paste, and then connect the electric current on the LBD pellet with the first one. The method was to connect the bridge and the anode wiring body using wire bonding. However, in order to obtain a high-density, large-sized display using a large number of LgDs, it is desirable to use a simpler connection method and a simpler structure to reduce the cost.

成しておく。The method for manufacturing a display device disclosed in Japanese Patent Application No. 55-127181, which was previously filed, is a method that addresses these requirements.
Protect the top electrode of the D pellet with the adhesive of the adhesive tape. Next, an insulating resin such as epoxy is filled into the gap between the substrate and the adhesive tape and cured. Furthermore, the adhesive tape is peeled off and a wiring body connecting the electrodes on the LID pellet is applied to the surface. Also, a patent application filed in 1982-1
No. 48837 and Japanese Patent Application No. 456-148839 further improve the above-mentioned method to shorten the process and eliminate defects in the wiring even in connectable boards. f. That is, as shown in FIG. 1, a desired metal button is first formed on a heat-resistant adhesive tape by pasting copper foil or the like and etching it.

An insulating resin 6 such as epoxy is infiltrated into the space between the adhesive tape and the substrate using capillary action and cured, and then the adhesive tape is removed.
次いで基板側に一体化された金属バタンとＩＪＤの上部

考えられる。However, 41 LED pellet top electric machine 3! When pressing the epoxy resin 6 with the adhesive side of the adhesive tape to prevent it from flowing in, the adhesive protrudes around the top surface of the LBD pellet, resulting in the creation of epoxy dents as shown by the person in the figure. In the wiring body connection process using silver paste printing in the subsequent process, disconnection of the silver paste often occurred. In order to eliminate the breakage of this conductive paste wiring body, a part of the metal pattern was
It is conceivable to provide it so as to extend to the upper surface electrode of the D pellet.

ルド・リーチが発生する等の問題があり、これらの点を
解決する為には高度な技術を必要とするものであった。However, in such a structure in which the metal batt is extended over the top surface of the IID pellet, the top surface of the LBD pellet cannot be protected with the adhesive surface of the adhesive tape, and the
Epoxy flows into the upper surface of the ED pellet. Therefore, it is impossible to make contact between the metal slam and the top electric machine of the LIID pellet using conductive paste, and as in the previously filed Japanese Patent Application No. 148846/1984 (not shown), adhesive tape is used in advance. A method has been devised to provide a low melting point metal or the like on the surface of the metal pattern and to make an electrical connection by welding. However, with this method, a large number of LED pellets must be arranged at uniform heights, and II.
It is necessary to make the thickness of the electrode a on the D pellet 10 μm or more, which may result in an expensive LED pellet F. Furthermore, ohmic electrodes such as gold and gold-zinc alloys, which are commonly used as electrodes on IID pellets, and low-melting point metals form eutectics and melt, resulting in so-called gold reach. There were problems, and solving these problems required advanced technology.
そこでこうした点の解決にあって発明者らは第２図に示

に成功した。That is, first, the wiring body 2 of @l provided on the substrate l
An adhesive tape 8 is prepared to hold a metal foil tab that will become the wiring body 5 of @2, which is insulated and perpendicular to the wiring body 5. This metal foil button S has an extended portion that runs above the LED pellet 3, and its thickness is 50 mm compared to the conventional thickness. What used to be am was made thinner to 5 to 40 μm. Also, the thickness of the adhesive of the adhesive tape 8 was about 25 μm, but it was about 25 μm thick! sOμm and box. Then, using this adhesive tape 8, the stirrup is aligned so that the extended part of the metal baton is on the LgD bellet 3, and then a process such as pressing it down with a flat plate from the surface side of the adhesive tape 8 is added. As a result, even with a structure in which a metal button is placed on the LIiD pellet 3, the surface of the LED pellet other than the metal button was successfully covered with adhesive.
しかしながら纂２図のＢに示すように粘着性テープ８と

この粘着性テープ８をはがすと。However, as shown in Fig. 2B, after filling the gap between the adhesive tape 8 and the substrate with epoxy resin 6 and curing it,
Peel off this adhesive tape 8.
ＬＥＤベレット３上面に配設された部位から金属パタン
Ｓがはがれてしまうことがわかった。It was found that the metal pattern S was peeled off from a portion disposed on the upper surface of the LED pellet 3.
本発明の目的は、多数個のＬＥＤペレットで。 The object of the present invention is to use a large number of LED pellets.

ディスプレイ装置を提供するにある。In addition, the present invention provides a display device that solves all of the aforementioned problems at once in a method and structure aimed at low-cost assembly of matrix-type display devices using connectable substrates. It is in.
すなわち、絶縁性の基板の一主面側にはｊｌｌの１線体
が形成され、この第１の配線体上には導電性ペースト等
で固着配列したＬＥＤベレットがある。That is, a jll single wire body is formed on one main surface side of an insulating substrate, and on this first wiring body there are LED pellets fixed and arranged with conductive paste or the like.

縁性樹脂に埋設固着されている。An insulating resin such as epoxy is filled and hardened on the surface of the substrate at the same height as the upper surface of the LBD bellet F. Father, on the surface opposite to the main surface of the board, there are LEDs in a predetermined part.
There is a wiring body @2 disposed across the pellet, and this second wiring body is embedded and fixed in the insulating resin in the other part except the upper surface of the LED pellet.

続が簡単で確実に行なえるようになった。For this reason, the second wiring body is not torn off in the process of peeling off the adhesive tape on the top surface of LgD Verets F, and therefore the second wiring body is not peeled off in the process of forming the third wiring body using conductive paste, etc., which is a later process. The wiring body and the electric bridge on the top of the LID pellet can now be easily and reliably connected.

特に有効である。The adhesive of the adhesive tape needs to be thin enough to adhere to the top surface of the LED pellet, but thick enough to provide mechanical strength. For example, if the thickness of the adhesive is 50 μm, a thickness of about 20 μm is preferable from the viewpoint of mechanical strength.
Furthermore, it is particularly effective to make the @2 wiring thinner than the thickness of the adhesive.
