Description
図1は実施形態1における有機ELディスプレイ1を示す。この有機ELディスプレイ1はそのA部を観察すると、図2に示すように、赤色(R)、緑色(G)、青色(B)を1組とした画素Pが、画面の横方向(X)、縦方向(Y)に多数並んで構成されている。すなわち、1画素PをR,G,Bの各副画素p1の集まりと定義する。フルハイビジョンの有機ELディスプレイ1では、X方向に1920個、Y方向に1080個の画素Pが並んでいる。図2はR,G,Bが各色毎にストライプ状に並んでいる様子を示しているが、この他にR,G,Bがデルタ配列であっても、本特許の趣旨に影響は及ばない。また、図2はR,G,Bを並置方式で並べたものであるが、R,G,Bが積層されている積層方式や、その他の並べ方であっても本特許の趣旨に影響は及ばない。
図17〜図19は実施形態2を示し、図17は実施形態2におけるパッシブ型有機ELディスプレイ1の多数の画素P(副画素p1)がストライプ状に並んだ画素配列を示す平面図である。図18は実施形態2におけるパッシブ型有機ELディスプレイ1の断面図である。図19は実施形態2における成膜プロセスのうち、磁性体4及び下部電極7の形成要領を示す工程図であり、図17のXIX −XIX 線対応箇所の断面図である。
図20及び図21は実施形態3を示し、図20は実施形態3におけるアクティブ型有機ELディスプレイ1の断面図である。図21は実施形態3における成膜プロセスのうち、磁性体4の形成要領を示す工程図である。
