It is made by a method of printing a dielectric and phosphor, and applying a transparent electrode to the entire surface of the substrate or plastic film to dry.

Pixels PX having a rectangular structure are formed on the front surface 110 on which the EL element of the display panel 100 disclosed in FIG. 1 is to be printed. In FIG. 1, the pixels PX are illustrated in a plane of a rectangle, but for convenience of description, as illustrated in FIG. 4D, the pixels PX are formed in a plurality of layers. The EL element is an inorganic EL element.

In addition, although the pixels PX are illustrated as rectangles in FIG. 1, the pixels PX are not limited thereto.

First, a plurality of front metal parts are formed by printing a conductive metal ink in a matrix form on the front surface of the display panel 100. (Step 11, see FIG. 4 (a)) The front metal part 120 having conductivity is about 1 mm. It is spaced at intervals of ˜1 cm to form a longitudinal matrix. The EL element is printed on the top metal part 120 to emit light through the metal junction part and the back electrode connection part of the back side 220.

The conductive front metal part 120 may be any metal having conventional electrical conductivity. Specifically, silver (Ag), copper (Cu), nickel, platinum (Pt), gold (Au), or palladium ( Pd) can be used.

Metal junctions electrically connected to the front metal parts are respectively formed on the rear side of the display panel, and rear electrode connection parts for applying a voltage to each of the metal junction parts are formed at the edges (see step 13 and FIG. 1 (b)).

On the rear surface 220, metal joints 240 electrically connected to the front metal parts 120 are connected to the rear electrode connectors 210 formed at edges by the wires 230. In addition, the rear electrode connecting parts 210 are connected to an external driving part. The driving unit will be described later.

A light emitting EL element is formed on each of the front metal parts to form a plurality of pixels (step 15, see Fig. 4 (b) (c) (d));

First, a mask is used to uniformly print the light emitting EL element on the front surface metal part 120 printed in a plurality of matrix forms on the front surface 110 of the display panel 100.

In this case, the EL element is formed by forming an insulator at both ends of the phosphor and applying an alternating voltage, and forming a ferroelectric only at the end face of the phosphor and emitting an alternating voltage by applying an alternating voltage. Apply. However, those skilled in the art can understand that the EL element can be formed also by the former method.

In step 15 of creating a plurality of pixels, first, a dielectric is printed on each of the front metal parts as a first printed layer (step 21).

That is, the ferroelectric BaTiO ₃ The paste is printed onto the first printing layer PR1 using a mask, wherein the thickness is about 200 μm to 500 μm, dried after printing, and the drying time is about 20 to 30 minutes. At this time, the drying atmosphere is dried in a normal atmosphere.

The phosphor is printed on the first printed layer as the second printed layer. (Step 23)

After the first printed layer PR1 is completely dried, the second printed layer PR2, which is a phosphor, is printed on the first printed layer PR1 using the same mask, and the printed phosphor is an EL phosphor and the thickness is about It is about 200 µm and dried in the same manner as in the method of drying the first printed layer PR1 after printing. The phosphor determines the color of the pixels PX, and the EL element can implement 14 colors.
