基板に2次元マトリクス状に配置された複数の発光部、
複数の発光部の上に配置され、各発光部に対応した第1マイクロレンズを備えた第1レンズ部、及び、
第1レンズ部の上に配置され、各発光部に対応した第2マイクロレンズを備えた第2レンズ部、
を少なくとも含んでいる。
基板に2次元マトリクス状に配置された複数の発光部、及び、
複数の発光部の上に配置され、各発光部に対応した柱状の導光部、
を含んでおり、
それぞれ隣接する導光部の間には隔壁部が設けられている。
第1の実施形態は、本開示の第1の態様に係る、表示装置に関する。
先ず、基板10に発光部25の駆動回路となるMOSFETなどを形成し、その上に平坦化膜20を形成する(図7A参照)。
次いで、平坦化膜20においてコンタクトプラグ21が配置される位置に開口を形成し、開口を含む全面に、アノード電極22を構成する導電材料層を形成する。その後、導電材料層をパターニングし、平坦化膜20上にアノード電極22を形成する(図7B参照)。
次いで、アノード電極22および平坦化膜20の上に、有機層23を、例えば、真空蒸着法やスパッタリング法といったPVD法、スピンコート法やダイコート法等のコーティング法等によって成膜する。その後、例えば真空蒸着法等に基づき、全面にカソード電極24を形成する(図8A参照)。
次いで、全面に、各発光部25に対応した第1マイクロレンズ31Aを備えた第1レンズ部30Aを形成する(図8B参照)。
その後、全面に平坦化膜40を形成する。次いで、周知の方法で、その上に、カラーフィルタ50を形成する(図9参照)。
その後、全面に、各発光部25に対応した第2マイクロレンズ31Bを備えた第2レンズ部30Bを形成する(図10参照)。次いで、例えばアクリル系接着剤から成る封止樹脂層60を介して透明基板90を貼り合わせる。こうして、図2に示した表示装置1を得ることができる。
第2の実施形態は、本開示の第2の態様に係る、表示装置に関する。
Sin(π/2-θ1)/Sin(θ2)=n2/n1
と表される。この式を変形すると、
Sin(θ2)=(n1/n2)×(1-Sin2(θ1))1/2
が得られる、これを上述したSin(θ2)<1/n2に代入して整理すると、
Sin(θ1)>(1-(1/n1)2)1/2
となる。従って、1/n1=(1-(1/n1)2)1/2となるように設定すると取り出せる光量が最大となる。よって、n1=21/2といった値にすることが好ましい。
先ず、基板10に発光部25の駆動回路、発光部25、カラーフィルタ50などを形成する(図20A参照)。尚、便宜のため、駆動回路を構成するトランジスタ、発光部25、カラーフィルタ50などは簡易的に示した。

その後、常温接合時の密着性を向上させるために、基板10に設けられた接合部280Aの上面に無機膜AL1を形成し(図20C参照)、また、接合部280Aに対応する透明基板90の部分に無機膜AL2を形成する(図21A、図21B参照)。無機膜は、例えば、シリコン(Si)、チタン(Ti)、銅(Cu)などの薄膜として形成することができる。
次いで、基板10の無機膜AL1と透明基板90の無機膜AL2を活性化する。例えば、Arプラズマを照射することによって、これらを活性化することができる(図22A参照)。
その後、基板10と透明基板90とを対向させ、真空中において常温接合を行う(図22B参照)。これによって、表示装置2を得ることができる。隔壁部BWの空間は真空などの低圧条件下であって、また無機膜は充分に薄い厚さで形成すれば足りるので、導光部280の上面と透明基板90とは密着した状態となる。
先ず、基板10に発光部25の駆動回路、発光部25などを形成する(図25A参照)。次いで、上述した[工程-220]を行い、導光部280と接合部280Aを形成する(図25B参照)。
また、透明基板90上にカラーフィルタ50を形成する(図25C参照)。必要に応じて、カラーフィルタ50を覆うように保護層291を形成する。尚、図24においては、保護層291の図示は省略した。
上述した[工程-220]を行い、基板10に設けられた接合部280Aの上面に無機膜AL1を形成し(図26A参照)、また、接合部280Aに対応する透明基板90の部分に無機膜AL2を形成する(図26B参照)。
上述した[工程-230]および[工程-240]を行うことによって、表示装置2Aを得ることができる(図26C参照)。
第3の実施形態は、本開示の第2の態様に係る、表示装置に関する。
第1の実施形態において説明した[工程-100]ないし[工程-120]を行い、発光部25が形成された基板10を得る(図29A参照)。その後、基板10上にカラーフィルタ50を形成する(図29B参照)。
次いで、全面に、第1マイクロレンズ381を構成するための材料層381Aを成膜し(図30参照)、グレートーンマスクGTMを介して露光を行う(図31参照)。その後、現像を行い、第1マイクロレンズ381を得る(図32参照)。
次いで、全面に、導光部380や隔壁部BWを形成するための充填材料層382Aを成膜し(図33参照)、導光部380に対応する部分が開口したマスクMSKを介して露光を行う(図34参照)。その後、現像を行い、充填層382と、隔壁部BWを得る(図35参照)。尚、ここでは、隔壁部BWは空間であるとして説明するが、誘電材料や金属材料で隔壁部BWを構成する場合には、空間として形成された隔壁部BWにこれらの材料を埋め込むようにすればよい。
次いで、全面に、第2マイクロレンズ383を構成するための材料層383Aを成膜し(図36参照)、グレートーンマスクGTMを介して露光を行う(図37参照)。その後、現像を行い、第2マイクロレンズ383を得る(図38参照)。
次いで、基板10と透明基板90とを、封止樹脂層60を介して貼り合わせることによって、表示装置3を得ることができる。
以上説明した本開示の表示装置は、電子機器に入力された映像信号、若しくは、電子機器内で生成した映像信号を、画像若しくは映像として表示するあらゆる分野の電子機器の表示部(表示装置)として用いることができる。一例として、例えば、テレビジョンセット、デジタルスチルカメラ、ノート型パーソナルコンピュータ、携帯電話機等の携帯端末装置、ビデオカメラ、ヘッドマウントディスプレイ(頭部装着型ディスプレイ)等の表示部として用いることができる。
図42は、レンズ交換式一眼レフレックスタイプのデジタルスチルカメラの外観図であり、図42Aにその正面図を示し、図42Bにその背面図を示す。レンズ交換式一眼レフレックスタイプのデジタルスチルカメラは、例えば、カメラ本体部(カメラボディ)411の正面右側に交換式の撮影レンズユニット(交換レンズ)412を有し、正面左側に撮影者が把持するためのグリップ部413を有している。
図43は、ヘッドマウントディスプレイの外観図である。ヘッドマウントディスプレイは、例えば、眼鏡形の表示部511の両側に、使用者の頭部に装着するための耳掛け部512を有している。このヘッドマウントディスプレイにおいて、その表示部511として本開示の表示装置を用いることができる。すなわち、本例に係るヘッドマウントディスプレイは、その表示部511として本開示の表示装置を用いることによって作製される。
