本開示の好適な実施形態について説明するに先立ち、本開示をより明確なものとするために、本発明者らが本開示に想到した背景について説明する。
図2を参照して、本開示の好適な一実施形態に係る表示装置の構成について説明する。図2は、本実施形態に係る表示装置の一構成例を示す断面図である。図2では、本実施形態に係る表示装置の模式的な一部断面図を示している。
図示する構成例では、第1基板11はシリコン基板から構成される。また、第2基板34は石英ガラスから構成される。ただし、本実施形態はかかる例に限定されず、第1基板11及び第2基板34としては、各種の公知の材料が用いられてよい。例えば、第1基板11及び第2基板34は、高歪点ガラス基板、ソーダガラス(Na2O、CaO及びSiO2の混合物)基板、硼珪酸ガラス(Na2O、B2O3及びSiO2の混合物)基板、フォルステライト(Mg2SiO4)基板、鉛ガラス(Na2O、PbO及びSiO2の混合物)基板、表面に絶縁膜が形成された各種ガラス基板、石英基板、表面に絶縁膜が形成された石英基板、表面に絶縁膜が形成されたシリコン基板、又は有機ポリマー基板(例えば、ポリメチルメタクリレート(ポリメタクリル酸メチル:PMMA)、ポリビニルアルコール(PVA)、ポリビニルフェノール(PVP)、ポリエーテルスルホン(PES)、ポリイミド、ポリカーボネート、若しくはポリエチレンテレフタレート(PET)等)によって形成され得る。第1基板11と第2基板34を構成する材料は、同じであってもよいし、異なっていてもよい。ただし、上述したように表示装置1は上面発光型であるから、第2基板34は、発光素子10からの光を好適に透過し得る、透過率の高い材料によって形成されることが好ましい。
発光素子10は、第1電極21と、第1電極21の上に設けられる有機層23と、有機層23上に形成される第2電極22と、を有する。より具体的には、第1電極21の上に、当該第1電極21の少なくとも一部を露出するように開口部25が設けられる第2部材52が積層されており、有機層23は、当該開口部25の底部において露出した第1電極21の上に設けられる。つまり、発光素子10は、第2部材52の開口部25において、第1電極21、有機層23及び第2電極22がこの順に積層された構成を有する。この積層構造が各画素の発光部24として機能する。つまり、発光素子10の、第2部材52の開口部25に当たる部分が発光面となる。また、第2部材52は、画素間に設けられ画素の面積を画定する画素定義膜として機能する。
第1基板11において、発光素子10を構成する第1電極21は、SiONからなる層間絶縁層16上に設けられている。そして、この層間絶縁層16は、第1基板11上に形成された発光素子駆動部を覆っている。
発光素子10の第2部材52に設けられる開口部25は、その側壁が、下方に向かうにつれて開口面積が増加するように傾斜したテーパ形状を有するように形成される。そして、当該開口部25に第1部材51が埋め込まれる。つまり、第1部材51は、発光素子10の発光面の直上に設けられる、発光素子からの出射光を上方に向かって伝播する層である。また、第2部材52の開口部25を上記のように形成することにより、第1部材51は、その積層方向における断面形状(すなわち、図示する断面形状)が略台形を有し、上方に底面を向けた切頭錐体形状を有する。
CF33aの位置ずれ量Lの設定方法について説明する。上述したように、本実施形態では、ある画素におけるCF33aの位置ずれ量Lを、当該画素に求められる視野角に応じて設定する。以下では、図8-図11を参照して、ある1つの画素に注目して、当該画素に求められる視野角がθ0である場合における、当該画素でのCF33aの位置ずれ量Lの設定方法について説明する。図8-図11は、CF33aの位置ずれ量Lの設定方法について説明するための図である。図8-図11では、いずれも、1つの発光素子10の発光部24、当該発光素子10に対応して設けられる1つのCF33a(図示する例ではCF33R)、及び表示装置1の表示面101を模擬的に図示している。
以上説明した実施形態についてのいくつかの変形例について説明する。
上述した実施形態では、発光素子10とCF33aとの相対的な位置ずれを発生させるために、図6及び図7を参照して説明したように、CF層33にCF33aの面積が他の通常のCF33aの面積とは異なる遷移領域201を設けていた。しかし、本実施形態では、発光素子10とCF33aとの相対的な位置ずれの発生方法は上記の方法に限定されず、他の方法であってもよい。
上述した実施形態では、輝度向上のために、画素間にリフレクタ53を設けていた(図2を参照)。しかしながら、本実施形態はかかる例に限定されず、視野角特性向上という目的を達成するためには、リフレクタ53は必ずしも設けられなくてもよい。
上記(3.CFの位置ずれ量について)で説明したように、上述した実施形態では、発光部24からの出射光がCF33Rの下面に入射する条件を規定することにより、CF33aの位置ずれ量Lを設定していた。しかしながら、本実施形態はかかる例に限定されない。例えば、発光部24からの出射光の特性、及びCF33aの特性等によっては、発光部24からの出射光がCF33aの側面に入射した場合であっても、色変換が適切に行われ、所望の特性の光を表示面101から出射させることが可能であると考えられる。従って、発光部24からの出射光がCF33aの側面に入射する場合も考慮して、CF33aの位置ずれ量Lを設定してもよい。
以上説明した実施形態及び各変形例に係る表示装置の適用例について説明する。ここでは、以上説明した実施形態及び各変形例に係る表示装置が適用され得る電子機器のいくつかの例について説明する。
以上、添付図面を参照しながら本開示の好適な実施形態について詳細に説明したが、本開示の技術的範囲はかかる例に限定されない。本開示の技術分野における通常の知識を有する者であれば、特許請求の範囲に記載された技術的思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、これらについても、当然に本開示の技術的範囲に属するものと了解される。
