Description
図1に本発明の発光表示装置の概略上面図の一例を示す。100は素子基板、101はソース線駆動回路、102、103はゲート線駆動回路、104は対向基板、105はシール材、106は画素部、107は走査線、108は信号線、109はFPC、110、111、112は配線である。本実施の形態では、上記のような回路で形成するが、本発明はこれに限定されず、パッシブマトリクス回路でもアクティブマトリクス回路であってもよく、周辺駆動回路としてICチップを前記COG方式やTAB方式によって実装したものでも、一体形成したものでもよい。また、ゲート線駆動回路、ソース線駆動回路は複数であっても単数であっても良い。
図1の本発明の発光表示装置のシール材105内部において、積層の厚さが最大となる領域は、信号線108と走査線107が重なる領域であり、その領域には、少なくとも、素子基板上に、信号線、層間絶縁膜、走査線、パッシベーション膜等が積層されている。
本発明の発光表示装置の例として、本実施例では、シール材105の形成領域に、図6に示すような積層構造を基板間隔補正手段として形成する。図6(a)に図1における線A―A'、図6(b)に線B−B'による断面図を、図6(c)に本発明の発光表示装置のシール材105の形成領域の上面図を示す。
本発明の発光表示装置の例として、本実施例では、シール材105の形成領域に、図10に示すような積層構造を基板間隔補正手段として形成する。図10(a)に図1における線A―A'、図10(b)に線B−B'による断面図を、図10(c)に本発明の発光表示装置のシール材105の形成領域の上面図を示す。
