Abstract
【解決手段】遮光膜202が横方向に延在し、縦方向に配列している。赤カラーフィルタ201R、青カラーフィルタ201B、緑カラーフィルタ201Gが所定の間隔を持って縦方向に延在している。青カラーフィルタ201Bは遮光膜を覆って横方向にも延在している。赤カラーフィルタ201Rおよび緑カラーフィルタ201Gに沿った断面においては、遮光膜202の上が他の部分に比較して、青カラーフィルタ201Bと遮光膜202の厚さの分高くなっている。スクリーン印刷時、この高くなった部分がメッシュのストッパーとなるので、メッシュによるムラの発生を防止することが出来る。
【選択図】図4
Description
図1において、TFT基板100上に対向基板200が設置されている。TFT基板100と対向基板200の間に液晶層300が挟持されている。TFT基板100と対向基板200とは額縁部に形成されたシール材20によって接着している。TFT基板100は対向基板200よりも大きく形成されており、TFT基板100が対向基板200よりも大きくなっている部分には、液晶セル1に電源、映像信号、走査信号等を供給するための端子部150が形成されている。また、端子部150には、走査線、映像信号線等を駆動するためのICドライバ50が設置されている。
図4(a)は表示領域10の画素構造の平面図であり、図4(b)は図4(a)のA−A断面図であり、図4(c)は図4(a)のB−B断面図である。図4(a)において、赤カラーフィルタ201R、青カラーフィルタ201B、緑カラーフィルタ201Gが各々所定間隔をおいて縦方向に延在している。図4におけるカラーフィルタ201の形成順序は赤カラーフィルタ201R、青カラーフィルタ201B、緑カラーフィルタ201Gの順である。
