次に、発光装置に用いることができる材料等を説明する。なお、本実施の形態中で先に説明した構成については説明を省略する。
素子層101は、少なくとも発光素子を有する。発光素子としては、自発光が可能な素子を用いることができ、電流又は電圧によって輝度が制御される素子をその範疇に含んでいる。例えば、発光ダイオード(LED)、有機EL素子、無機EL素子等を用いることができる。
接着層には、紫外線硬化型等の光硬化型接着剤、反応硬化型接着剤、熱硬化型接着剤、嫌気型接着剤などの各種硬化型接着剤を用いることができる。これら接着剤としてはエポキシ樹脂、アクリル樹脂、シリコーン樹脂、フェノール樹脂、ポリイミド樹脂、イミド樹脂、PVC(ポリビニルクロライド)樹脂、PVB(ポリビニルブチラル)樹脂、EVA(エチレンビニルアセテート)樹脂等が挙げられる。特に、エポキシ樹脂等の透湿性が低い材料が好ましい。また、二液混合型の樹脂を用いてもよい。また、接着シート等を用いてもよい。
絶縁層205、絶縁層255には、無機絶縁材料を用いることができる。特に、前述の透水性の低い絶縁膜を用いると、信頼性の高い発光装置を実現できるため好ましい。
導電層156、導電層157、導電層294、及び導電層296は、それぞれ、トランジスタ又は発光素子を構成する導電層と同一の材料、同一の工程で形成できる。また、導電層280は、トランジスタを構成する導電層と同一の材料、同一の工程で形成できる。
着色層259は特定の波長帯域の光を透過する有色層である。例えば、赤色の波長帯域の光を透過する赤色(R)のカラーフィルタ、緑色の波長帯域の光を透過する緑色(G)のカラーフィルタ、青色の波長帯域の光を透過する青色(B)のカラーフィルタなどを用いることができる。各着色層は、様々な材料を用いて、印刷法、インクジェット法、フォトリソグラフィ法を用いたエッチング方法などでそれぞれ所望の位置に形成する。
次に、発光装置の作製方法を図6及び図7を用いて例示する。ここでは、具体例1(図1(C))の構成の発光装置を例に挙げて説明する。
