Description

The present invention relates to a display plate including a timepiece dial, a clock parting plate, an instrument dial, and the like.
The present invention also relates to equipment using such a display board as a display board of equipment such as a display board for a clock, a desk calculator, an automobile, an instrument panel of an airplane, a mobile phone, etc. .

Conventionally, for example, various designs have been applied to a timepiece dial in order to enhance a sense of quality as an accessory and to give a three-dimensional appearance to the timepiece dial.
FIG. 9 is a cross-sectional view of a conventional timepiece dial 100.

  In the present specification, “upper surface side” and “upper side” are sides arranged on the viewing side, and “lower surface side” and “lower side” are opposite to the viewing side, for example, solar The side where the cell, antenna, movement, etc. are arranged.

  The timepiece dial plate 100 is configured by printing and vapor-depositing a pattern 130 on at least one surface of a single substrate 120. As a material for the substrate 120, natural shellfish, precious stones, and the like are used in addition to glass, metal, resin, and the like in order to enhance luxury.

However, the timepiece dial 100 described above has a three-dimensional effect because it represents a pattern on a single substrate.
For this reason, Patent Document 1 (Japanese Utility Model Laid-Open No. 57-2477) proposes a timepiece dial having a higher three-dimensional effect.

FIG. 10 is a cross-sectional view of a conventional timepiece dial 200 shown in Patent Document 1. In FIG.
The timepiece dial plate 200 is configured by bonding two transparent glass plates 220 and 240 together with an adhesive layer 260. Then, the pattern 230 is printed and vapor-deposited on the upper and lower surfaces of the transparent glass plate 220 so as to appear three-dimensionally.

Further, Patent Document 2 (Japanese Utility Model Publication No. 63-84592) proposes a timepiece dial having a higher three-dimensional effect and improved color.
FIG. 11 is a cross-sectional view of a conventional timepiece dial 300 shown in Patent Document 2. As shown in FIG.

The timepiece dial plate 300 is configured by bonding a surface plate 340 made of photosensitive glass and a substrate 320 with an adhesive layer 360 so that the adhesive layer 360 cannot be seen from the outside on the lower surface of the surface plate. A colored coating 350 is lined. In the surface plate 340, a pattern 330 formed by irradiating and exposing to ultraviolet rays is colored and formed on the entire thickness of the surface plate 340 so that it can be seen three-dimensionally.
Japanese Utility Model Publication No. 57-2477 Japanese Utility Model Publication No. 63-84592

  However, in the conventional timepiece dial plate 200 as in Patent Document 1, as shown in FIG. 10, bubbles are mixed in the adhesive layer 260 existing between the two transparent glass plates 220 and 240 at the time of bonding. In this way, the bubbles mixed in the adhesive layer 260 are visually recognized and poor in appearance, and a sufficient high-class feeling cannot be obtained.

  Further, in the conventional timepiece dial 300 as in Patent Document 2, as shown in FIG. 11, although the colored coating film 350 is lined so that air bubbles mixed in the adhesive layer 360 cannot be visually recognized, The presence of the colored coating film 350 makes it difficult for the substrate 320 on the lower surface of the colored coating film 350 to be visually recognized.

  By the way, in order to obtain a high-class feeling due to the texture of the shell, a shell is sometimes used for the timepiece dial. In this case, in order to give the watch dial a three-dimensional effect, it is conceivable to engrave the shell and form it three-dimensionally, but it is difficult to form a coating film on the upper surface of the engraved shell. For this reason, a coating film was formed on the shellfish, and a further three-dimensional effect and a high-class feeling could not be obtained.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a display panel that is excellent in stereoscopic effect and luxury, and has high impact resistance and strength.

What is necessary is just to select a thing, and when using as a display board of apparatuses which receive electromagnetic waves, such as a radio timepiece, what is necessary is just to comprise from the material which lets electromagnetic waves pass.

  On the other hand, the material of the transparent substrate 14 is not particularly limited as long as it is transparent or semi-transparent, and the substrate body 12 existing below can be selected from materials that can be seen through the transparent substrate 14.
