Definitions
- Embodiments of the present invention relate to display technology.
- an optical element that is difficult to counterfeit or imitate may be formed on the polymer carrier, or such an optical element may be attached to the polymer carrier.
- this optical element include a hologram and a phosphor.
- this optical element there is also one in which a concave-convex structure is formed in a universal line shape on a metal thin film (see Patent Document 1).
- Such an optical element has a so-called opal effect in which the shading and brilliance formed by the uneven structure changes when the observation angle is changed.
- Printing may be used to prevent counterfeiting of securities.
- watermark printing may be used (see Patent Document 2).
- Watermark printing uses transparent ink to print on paper and causes a difference in transmittance between a printed portion and a non-printed portion. When you hold the watermark-printed paper over the light, the shades corresponding to the printing of characters and patterns are displayed.

Abstract
Description
例えば、キャリアが紙からなる場合、透かし印刷を用いることがある(特許文献2参照)。透かし印刷は、透明インキを使用して用紙への印刷を行い、印刷部と非印刷部とに透過率の相違を生じさせるものである。透かし印刷を行った用紙を光にかざすと、文字や絵柄などの印刷に対応した濃淡が表示される。
そこで、本発明は、顕像を明るく表示することが可能な技術を提供することを目的とする。
ポリマーからなるキャリアは、成形が容易であり、また、可撓性を付与することも容易である。
このように、サブ領域には、様々な配置が可能である。
表示体の形状に制限はないが、シート又はフィルム状である場合には、その応用の範囲が広い。例えば、シート又はフィルム状の表示体は、銀行券、株券、商品券、及びチケットなどの有価証券として利用することができる。そして、表示体がシート又はフィルム状である場合、これを折るか又は曲げるといった簡単な動作により、潜像を顕像化することができる。
このような配置によると、表示体を第1部分から第2部分へ変形させる際に、第1及び第2部分を互いに対して高い精度で及び容易に位置合わせすることができる。
表示体が冊子体である場合も、その応用の範囲が広い。冊子体としての表示体は、例えば、パスポート又は預金通帳などの通帳として利用することができる。表示体が冊子体である場合、例えば、第1部分は、冊子体を閉じた状態において重なり合う2つの頁部の一方又はその一部であり、第2部分は、それら頁部又はその一部である。ここで、「頁部」は、冊子体を構成しているシートのうち、表側の1頁と裏側の1頁とに対応した部分である。即ち、「頁部」は、冊子体を構成しているシートのうち、一方の面に1頁が割り当てられ、他方の面に別の1頁が割り当てられる部分である。例えば、冊子体が2つ折りされたシートを含んでいる場合、そのシートのうち折り目で区分された2つの部分の各々が「頁部」である。第1状態は、例えば、第1部分を含んだ頁部と第2部分を含んだ頁部とが互いから離間するように冊子体を開いた状態である。第2状態は、例えば、第1部分を含んだ頁部が露出し且つ第2部分を含んだ頁の上に位置するように冊子体を開いた状態である。この構成によると、頁をめくるといった簡単な動作により、潜像を顕像化することができる。
図1は、本発明の第1実施形態に係る表示体が第1状態にあるときに呈する構造を概略的に示す平面図である。
キャリア11の長辺は、125mm以上200mm以下の範囲内にあることが好ましい。この範囲だと折り曲げやすい。
先ず、図4に示すように、金型基材31の主面に、マスク層32を形成する。マスク層32には、第2領域R2と第1部分A1以外の部分とに対応したパターンが形成されている。
図13は、第1部分に採用可能な構造の一例を概略的に示す平面図である。図14は、第2部分に採用可能な構造の一例を概略的に示す平面図である。図15は、図13の第1部分と図14の第2部分とを重ね合わせた状態を概略的に示す平面図である。図16は、第1及び第2部分にそれぞれ図13及び図14の構造を採用した表示体が第1状態で表示する画像の一例を概略的に示す平面図である。図17は、第1及び第2部分にそれぞれ図13及び図14の構造を採用した表示体が第2状態で表示する画像の一例を概略的に示す平面図である。
図18は、本発明の第2実施形態に係る表示体において、第1部分に採用可能な構造の一例を概略的に示す平面図である。図19は、本発明の第2実施形態に係る表示体において、第2部分に採用可能な構造の一例を概略的に示す平面図である。図20は、図18の第1部分と図19の第2部分とを重ね合わせた状態を概略的に示す平面図である。
図21は、本発明の第3実施形態に係る表示体において、第2部分に採用可能な構造の一例を概略的に示す平面図である。図22は、図18の第1部分と図21の第2部分とを重ね合わせた状態を概略的に示す平面図である。
図23は、本発明の第4実施形態に係る表示体において、第1部分に採用可能な構造の一例を概略的に示す平面図である。図24は、本発明の第4実施形態に係る表示体において、第2部分に採用可能な構造の一例を概略的に示す平面図である。図25は、図23の第1部分と図24の第2部分とを重ね合わせた状態を概略的に示す平面図である。
図26は、本発明の第5実施形態に係る表示体を概略的に示す部分切開斜視図である。図27は、図26に示す表示体の他の部分切開斜視図である。
図31は、本発明の第6実施形態に係る表示体において、第1部分に採用可能な構造の一例を概略的に示す部分切開斜視図である。図32は、図31に示す構造の他の部分切開斜視図である。
図33は、本発明の第8実施形態に係る表示体において、第1部分に採用可能な構造の一例を概略的に示す断面図である。
図34は、本発明の第8実施形態に係る表示体において、第1部分に採用可能な構造の一例を概略的に示す断面図である。

図36は、本発明の第10実施形態に係る表示体を概略的に示す平面図である。なお、図17には、冊子体を開いた状態で描いている。
上述した実施形態には、様々な変形が可能である。
例えば、第3及び第4実施形態では、第1周期P1は、サブ領域の配列方向におけるセルCの寸法の2倍である。第1周期P1は、サブ領域の配列方向におけるセルCの寸法の2倍からずれていてもよい。この場合、セルCのX方向における寸法の2倍と第1周期P1との差は、例えば、セルCのX方向における寸法の2倍に対して±25%の範囲内とする。
以下のようにして、第3実施形態において説明した表示体10を製造した。
先ず、キャリア11として、透明フィルム(品名:OHPフィルム(カラーLBP&カラーPPC用)、販売元:コクヨ株式会社、材質:R-PETフィルム、厚さ:0.10mm)を用意した。このキャリア11上に、レーザープリンタ(株式会社沖データ MICROLINE(登録商標)VINCH C931dn)を用いて印刷層12を形成した。このようにして、第2部分A2を形成した。
