However, in order to form a dispersion type EL lamp having the above-mentioned conventional structure, at least a light emitting layer 3, an insulating layer 4, and a back surface are formed on a transparent electrode layer 2 formed by sputtering or the like. Although it can be configured by disposing three layers of the electrode layer 5, in reality, since the average particle diameter of the phosphor powder contained in the light emitting layer 3 is as large as about 30 μm, the phosphor powder, the synthetic resin, and the organic Using a paste for the luminous body layer 3 mixed with a solvent, etc., the coated surface of the luminous body layer 3 is printed and dried by evaporating the organic solvent after printing by screen printing. When the layer 4 is printed with the layer 4 overlaid, pinholes are likely to be generated. When the back electrode layer 5 is overlaid and printed, the back electrode layer 5 and the transparent electrode layer 2 are printed.
However, there is a problem that if a voltage of AC50V to AC150V is applied between the transparent electrode layer 2 and the back electrode layer 5 to cause lighting, a withstand voltage failure is likely to occur.

Therefore, in order to ensure the withstand voltage without generating pinholes, the insulating layer 4 is printed three to four times using a low-viscosity paste for the insulating layer 4 diluted with a large amount of an organic solvent. In order to prevent the back electrode layer 5 from being exposed, a protective insulating layer 6 may be formed, or the external extraction electrodes 7A and 7B may be formed using a silver resin-based paste.
7 to 8 times were necessary including the formation of

However, even if the insulating layer 4 is printed as described above, it is impossible to completely eliminate pinholes because the unevenness of the surface of the light emitting layer 3 is not constant. There was a problem that a withstand voltage defect was found even in a withstand voltage test.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1A is a plan view of a partial cross section of a dispersion-type EL lamp according to a first embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along line XX of FIG. In the figure, 1 is a transparent resin film as an insulating substrate, 11
Is a plurality of transparent conductive patterns, which are formed by dividing a transparent conductive film provided on one surface of the transparent resin film 1 into stripes by fine lines, and a plurality of two divided into two sets for each separated sheet. Each is connected at the end.

Reference numeral 12 denotes a light emitting layer printed and formed on the transparent conductive pattern 11, and reference numeral 13 denotes a protective insulating layer formed of a white high dielectric substance and printed so as to cover the light emitting layer 12. .

FIG. 2 (a) is a plan view showing a conductive pattern of the dispersion type EL lamp constructed as described above, and FIG. 2 (b) shows a luminous body layer formed thereon sequentially. FIG. 3 is a plan view showing a conductive pattern 1 formed on a transparent resin film 1 in a stripe shape so as not to contact each other;
1, only the odd-numbered conductive patterns 11A are collectively connected at one end and provided to protrude to the side.
It is connected to the first electrode 14 for connection with an external circuit (not shown), and only the conductive patterns 11B of the even-numbered rows are collectively connected at the other end and are provided so as to protrude to the same side as the first electrode. The state connected to the second electrode 15 is shown.

In each of the above drawings, the thickness direction is shown larger than the actual size for easy understanding, and the line width and pitch of the stripe-shaped conductive pattern 11 are also larger than the actual size. Is less than the actual value.

Next, the dispersion type E constructed as described above is used.
The operation of the L lamp will be described. When an AC voltage is applied between the first and second electrodes 14 and 15 from an external circuit, a potential difference gradient is generated between the stripe-shaped adjacent conductive patterns 11A and 11B, and the potential difference gradient is generated. The phosphor in the light emitting layer 12 located in the electric field generated by the light emission emits light, and this light directly passes through the transparent resin film 1 or is reflected by the protective insulating layer 13 having a white high dielectric property, so that the light on the transparent resin film 1 side The light emitting surface emits light uniformly.

The components of the dispersion-type EL lamp having the above-described configuration will be described in detail. The conductive pattern 11 is made of a transparent resin film 1 such as a polyester film or a polycarbonate film made of indium tin oxide or the like.

/ □ is formed by cutting the transparent conductive film in a half-cut shape so as not to cut the transparent resin film 1 using a laser, etching, or a mold having a cutting blade.

The stripe-shaped conductive pattern 11 has a line width of 20 to 100 μm, and each of the adjacent conductive patterns 11
The gap between A and 11B is desirably 20 to 100 μm. If the pattern line width is less than 20 μm, the pattern resistance of the striped conductive pattern 11 increases. When the pattern line width is more than 100 μm, the phosphor at the center of the width of the conductive pattern 11 does not emit light sufficiently when light is emitted.

The adjacent conductive patterns 11A, 11A
If the gap B is less than 20 μm, the adjacent conductive patterns 11
A and 11B are apt to be short-circuited, and if it exceeds 100 μm, the brightness tends to be reduced.

Next, the phosphor for the luminous body layer 12 is prepared by mixing a phosphor powder for EL with a cyanoethyl cellulose resin having a high dielectric constant.

Using a paste dispersed in an insulating synthetic resin, pattern printing and drying are respectively performed by screen printing or the like, and a membrane switch or the like is used to connect the first and second electrodes 14 and 15 to an external circuit. A connection pattern (not shown) using a silver resin-based paste or a carbon resin-based paste used for printing can be formed by the same method as described above, and connection to an external circuit is made by first and second electrodes. 14 and 15 may be used as they are as electrodes for external extraction, but silver resin paste or the like is superimposed on the electrodes and connected. Better to form a turn can stabilize the contact at the time of connection.

When the protective insulating layer 13 is not provided, light is emitted on both the transparent resin film 1 side and the light emitting layer 12 side. By coloring the layer 13 white and effectively reflecting the light emitted from the phosphor, the protective insulating layer 13
Although no light is emitted on the side where is formed, the luminance of the light emitting surface on the transparent resin film 1 side can be increased.

Further, a high dielectric resin and a high dielectric fine powder are applied to the paste for the protective insulating layer 13 to form the protective insulating layer 1.
By increasing the dielectric constant of 3, the phosphor can be more effectively applied with a potential, and the luminance of the light emitting surface on the transparent resin film 1 side can be further increased.
The effect of increasing the luminance is small unless the dielectric constant of the substrate is not less than 10.

As described above, according to the present embodiment, at least one layer, and if necessary, two or three layers are formed on the conductive pattern 11 in the form of stripes by printing. Thus, it is possible to obtain a distributed EL lamp in which a short circuit between electrodes and a withstand voltage failure are unlikely to occur.

As a matter of course, the paste for the light emitting layer may be colored in advance by adding a fluorescent dye or a fluorescent pigment to a synthetic resin in which the fluorescent material is dispersed and coloring.

In this case, the protective insulating layer is also colored in the same manner, so that the emission color of the phosphor can be freely converted to the emission color together with the coloring of the paste for the emission layer.
