EL elements are useful as surface light sources that can be selected or combined in various shapes and sizes, and have recently been put into practical use as various lighting or indicating/display devices. Particularly in the case of a large-screen display device, a plurality of EL elements can be connected and combined vertically and horizontally.

る。 Conventionally, such an EL element 1 basically has a laminated structure as shown in FIG. That is, an insulating layer 3 containing, for example, barium titanate (BaTiO 3 ) or the like is formed on the upper surface of a back electrode 2 made of aluminum or the like, and a light emitting layer 4 containing a phosphor such as zinc sulfide (ZnS) is formed thereon. ,
Furthermore, a transparent conductive film 5 having an indium oxide (ITO) vapor deposited film and an extraction electrode 5a for external power connection is superimposed on the light emitting layer 4 such that the ITO vapor deposited film faces the light emitting layer 4. At the same time, the extraction electrode 2a is attached to the back electrode 2 to form an EL cell 6, and then a moisture-proof film 7 is sealed from above and below to the EL cell 6 by thermocompression bonding or the like.

つた。 However, in the EL element 1 configured in this way, the moisture-proof film 7 and the extraction electrode 5a are
and 2a are the light emitting part of the EL element 1, that is, the EL cell 6
Since it is larger than the EL cell 6 and spreads out on the same surface as the EL cell 6, it has a part (non-light emitting part) that does not emit light along the outer periphery of the EL cell 6, which is the light emitting part. Therefore, when combining with other EL elements to produce, for example, a large-screen display device, gaps in the display pattern will occur between the connected EL elements, and the amount of information in the display pattern will decrease. There are drawbacks such as a decrease in the information density due to a decrease in the information density, and a decrease in the visibility of the display pattern due to an increase in the area of the non-light-emitting portion.
本考案は、以上の点に鑑み、発光部の周りの非
発光部の面積をできるだけ小さくしたEL素子を

In view of the above points, the present invention aims to provide an EL element in which the area of the non-light emitting part around the light emitting part is made as small as possible.

According to the present invention, the above object is achieved by forming oblique sides by diagonally cutting out the four corners of an EL cell constructed by sequentially laminating a back electrode, an insulating layer, a light emitting layer, and a transparent conductive film. After sealing the above-mentioned EL cell from above and below by thermocompression bonding or the like using a moisture-proof film having a shape that has oblique sides at the four corners corresponding to the shape of the cell, seal the moisture-proof film on the extension line of the four sides of the EL cell at approximately the center of the oblique side of the moisture-proof film. This is achieved by using an EL element in which a notch is provided and the peripheral edge of the moisture-proof film is bent toward the back side along the four sides of the EL cell, preferably at an angle of 90 degrees or more.

報密度が高められ、しかも視認性が良くなる。 According to this invention, when the peripheral edge of the moisture-proof film is bent toward the back side along the four sides of the EL cell, a notch is preferably formed approximately in the center of the oblique side of the moisture-proof film on the extension line of the four sides of the EL cell. Since the is provided with a semicircular notch, the periphery of the moisture-proof film can be easily bent without wrinkles occurring at the four corners of the moisture-proof film. In other words, the peripheral edge of the moisture-proof film, which is unavoidable along the outer periphery of the EL cell, is bent toward the back side of the EL element, reducing the area exposed on the surface of the EL element, especially at 90 degrees. When the bending angle is above, the exposed area of the peripheral edge of the moisture-proof film is almost eliminated, so it is essentially the same as if it does not exist. Thus, when a plurality of EL elements according to the present invention are combined and mounted in, for example, a large-screen display device, the non-light-emitting parts that exist between the light-emitting parts of each EL element are extremely small and can be almost ignored. , the amount of information in the display pattern increases, increasing the information density and improving visibility.

来のEL素子１と同様の構成である。 Here, the insulating layer 13 of the EL cell 16 is made of a thermoplastic resin whose dielectric constant is increased by cyanoethylating ferroelectric powder such as barium titanate (BaTiO 3 ) on the upper surface of the back electrode 12 made of aluminum or the like. It is formed by dispersing a paste into a thermoplastic resin, applying it by screen printing, etc., and drying it. On top of that, a phosphor such as zinc sulfide (ZnS) is similarly dispersed in a thermoplastic resin, and then it is formed by screen printing, etc. The light emitting layer 14 is formed by coating and drying. Furthermore, a transparent conductive film 15 formed by vapor-depositing indium oxide (ITO) on one surface of a polyester film or the like is further placed on the light emitting layer 14.
The EL cell 16 is formed by thermocompression bonding the ITO vapor deposited film so as to face the light emitting layer 14.
At that time, the back electrode 12 and the transparent conductive film 15
Each has an extraction electrode 12a for connecting to an external power supply.
and 15a are attached, and the configuration up to this point is similar to that of the conventional EL element 1.

First, the four corners of the EL cell 16 are cut diagonally as shown in the figure to form the oblique side portions 16a, and then
A moisture-proof film 17 having oblique sides 17a at the four corners corresponding to the shape of the EL cell 16 is sealed from above and below the EL cell 16 by thermocompression bonding or the like, and then the moisture-proof film 17 is sealed approximately at the center of the oblique sides 17a of the moisture-proof film 17. A semicircular notch 17b is formed on the extension line of the four sides of the EL cell 16.

Element 11 is obtained. At this time, the size of the oblique side 16a of the EL cell 16 is the same as that of the moisture-proof film 17.
It is selected to form a right-angled isosceles triangle whose height is the width A of the portion protruding from the EL cell 16.

て、本EL素子１１が完成する（第２図参照）。 From this state, the moisture-proof film 17 is bent toward the back side along the four sides of the EL element 11, and the extraction electrodes 12a and 15a are bent at the same time, thereby completing the EL element 11 (see FIG. 2).

, the moisture-proof film 17 is not wrinkled at the four corners when the moisture-proof film 17 is bent, and the moisture-proof film 17 can be easily bent toward the back side.

きて好ましい。 In addition, when bending the periphery of the moisture-proof film, it is best to bend it at an angle of at least 90 degrees.
This is preferable because the light emitting surfaces of the EL elements can be arranged without gaps.

Since the peripheral edge of the moisture-proof film 17, which is a non-light-emitting part, is bent toward the back side, the area of the non-light-emitting part on the surface of the EL element 11 is extremely small compared to the area of the EL cell 16, which is a light-emitting part. It can be.

As described above, according to the present invention, the back electrode,
The EL cell is constructed by sequentially laminating an insulating layer, a light emitting layer, and a transparent conductive film.The four corners of the EL cell are cut out diagonally to form the oblique sides.
After sealing the above-mentioned EL cell from above and below by thermocompression bonding or the like using a moisture-proof film having oblique sides at the four corners corresponding to the shape of the cell, the moisture-proof film is placed on the extension line of the four sides of the EL cell at approximately the center of the oblique side of the film. Provide a cutout, preferably a semicircular cutout, and
The EL element is constructed by bending the peripheral edge of the moisture-proof film toward the back side along the four sides of the cell. Therefore, in conventional EL devices, the peripheral edge of the moisture-proof film, which is unavoidably present along the outer periphery of the light emitting part (EL cell), is bent toward the back side of the EL device, thereby preventing the EL device from being exposed. The area of the non-luminescent part exposed on the surface becomes very small, especially when the bending angle is 90 degrees or more, the exposed area almost disappears, so it is essentially the same as there being no non-luminous part. becomes. Therefore, when combining multiple EL elements configured in this way to form a large screen display device, each
The non-light-emitting portions existing between the light-emitting portions of the EL element are extremely small and can be almost ignored, the amount of information in the display pattern is increased, the information density is increased, and the visibility is improved.
