Abstract
Description
図13は、比較例の画素領域PXを概略的に示す平面図である。図13に示す比較例は、コンタクトホールCH3が画素領域PXの外側に設けられている点で、本実施形態と相違している。コンタクトホールCH3は、一例では、走査線G1と重なっている。また、図13は、走査線G2と重なるコンタクトホールCH3a、及びコンタクトホールCH3aと重なる第2透明電極IT2aを示している。
図16は、本実施形態の第1変形例を示す平面図である。第1変形例は、図において斜線を付して示すように、コンタクトホールCH3が設けられた領域内に絶縁層18が形成されている点で、図4に示す例と相違している。また、第3透明電極IT3の開口OPのエッジE3は、部分的にコンタクトホールCH3と重なっている。換言すると、第3透明電極IT3の一部は、絶縁層18と重なっている。
