The bonding between the resin substrate 11 and the decorative thin film member 12 is performed by, for example, bonding with an adhesive, film bonding, fusion bonding, high-frequency bonding, or the like. First display panel 1
At 0, a pattern is formed on the resin substrate 11.
The pattern is applied to the resin substrate 11 by an injection molding method of injecting a resin into a mold having a pattern formed thereon (hereinafter, referred to as a “pattern mold”); the pattern is formed on the resin substrate by hot pressing using the pattern mold. The pattern is transferred by a pattern transfer method; or a mechanical processing method such as engraving or rubbing. Among these, the pattern transfer method is particularly preferably employed in the present invention.

In the pattern transfer method, as shown in FIGS.
The method includes a step of manufacturing the electroforming mold 1 having a pattern surface, and a step of hot-pressing the mold surface of the electroforming mold on the resin substrate 11. When manufacturing the electroforming mold 1 having a patterned surface, first, the surface pattern of the patterned article 2 is formed into a metal mold by an electroforming method. Specifically, electroforming is performed on the article 2 having a pattern. When the article 2 does not have conductivity, the article 2 is given conductivity by forming a metal film 3 on the surface of the article 2 or the like.

Here, as the article 2 having the pattern,
Cloth, paper, stone, wood, pyroxene, leaves, petals, shells, leather, artificial products having various fine patterns (artificial leather, sculpture, engraving), etc., preferably cloth, paper, stone, wood ,
Pyroxene, leaves, sculpture and engraving are used. As shown in FIG. 2, a pattern is formed on the surface of the article 2 (surface irregularities in FIG. 2). In FIG. 2, the description of the back surface of the article 2 is omitted.

First, in order to impart conductivity to the surface of the article 2, the surface of the article 2 is cleaned, and then a metal film 3 is formed on the surface of the article 2. The metal film 3 is formed by, for example, a vacuum deposition method, an ion plating method, a sputtering method, an electroless plating method, a silver mirror reaction, or the like. Metal film 3
Is formed from a metal such as silver or gold or an alloy thereof,
The thickness is not particularly limited, but about 1 to 30 μm,
Preferably, about 1 to 10 μm is appropriate.

As described above, when the article 2 has conductivity, it is not necessary to form the metal film 3. Next, a release treatment is performed on the surface of the metal film 3 as necessary. When the article 2 has conductivity, the surface of the article 2 is directly subjected to a peeling treatment. The peeling treatment can be performed by applying aselenic acid. If the peeling treatment is performed, the peeling of the electroforming mold 1 becomes easy.

Next, as shown in FIG. 3, an electroforming mold 1 is formed by depositing a metal on the surface of the article 2 or the surface of the metal film 3 by an electroforming method (electroforming method). As a material of the electroforming mold 1, a metal such as nickel, copper, or iron, or an alloy thereof is preferably used. The thickness of the electroforming mold 1 is in the range of 100 to 300 μm, preferably 100 to 250 μm, particularly preferably 100 to 200 μm. When the thickness of the electroforming mold 1 is in this range, the resin substrate 11 described later is not deformed, and the heat transfer at the time of hot pressing is good.

The conditions for the electroforming are not particularly limited, and are appropriately selected from conventionally known electroforming (plating) conditions. Although not limited in any way, the following briefly describes the electroforming conditions for obtaining a 200 μm-thick electroforming mold 1 using nickel metal. First, as a pretreatment, the surface of the patterned article 2 or the metal film 3 is subjected to electrolytic degreasing, water washing, acid neutralization, water washing, peeling treatment (potassium dichromate), and water washing.

Next, using a nickel plating bath (450 g / liter of nickel sulfamate, 40 g / liter of boric acid), electroforming is performed at 265 AH (1 A / dm ² ) at a liquid temperature of 50 ° C. Thus, an electroforming mold 1 having a thickness of 200 μm is obtained. Next, the electroforming mold 1 is peeled from the surface of the article 2 or the surface of the metal film 13 to obtain an electroforming mold 10 having a patterned pattern surface. The obtained electroforming mold 1
Is die-cut as necessary according to the desired shape of the display panel.

Next, as shown in FIGS. 4 and 5, the mold pattern is transferred to the resin substrate 11. In order to transfer a pattern to the resin substrate 11, the pressed pattern surface of the electroforming mold 1 is opposed to the resin substrate 11 and hot-pressed.

Can be reduced to about 30 seconds. Further, at the time of hot pressing, the electroforming die 1 may be attached to a hot press head. Thereby, the resin substrate 11 after the hot pressing can be easily separated from the electroforming mold 1, and the productivity can be improved.

By such hot pressing, the resin substrate 11
Then, the pattern formed in the mold of the electroforming mold 1 is transferred thereto, and the electroforming mold 1 is peeled to obtain the resin substrate 11 having the pattern. Furthermore, a transparent resin film having a pattern on both surfaces can be manufactured by simultaneously or sequentially hot pressing the pattern surface of the electroforming mold 1 on both surfaces of the resin substrate 11.

When performing hot pressing on both sides simultaneously, the electroforming mold 1 may be attached to the upper and lower hot press heads. When performing hot pressing on both sides sequentially, heat is applied to one side. After the pressing, the resin substrate 11 is turned over, and the other surface may be subjected to hot pressing. In the method of manufacturing the patterned resin substrate 11 described above, the case where the patterned resin substrate 11 is manufactured individually one by one has been described. However, the electroforming mold 1 having a plurality of pattern patterns is manufactured, and this is performed.
