- 入光面と、反射面と、出光面から成り、上記入光面は線状のランプ源から発射される光を受けるように配置され、上記反射面は、断面V字型で2つの斜辺を有すると共に上記ランプ源に平行に走向する複数の導光体を設け、上記出光面は、上記反射面に対向して、また、上記入光面に相隣して設置され、さらに、断面V字型で2つの斜辺を有すると共に上記ランプ源に垂直に走向する複数の導光体を設けて、成る導光板において、
上記出光面の中央領域の導光体は、断面V字型で正のV字型であり、上記出光面の両側領域の導光体は、上記中央領域の導光体から両側に偏移し、長い斜辺と短い斜辺を有し、該短い斜辺は上記中央領域の導光体に面し、該長い斜辺は上記出光面の両側縁方向に面し、これら長い斜辺と短い斜辺はそれぞれ上記出光面に対して挟角θ1およびθ2を有し、該挟角θ1が、該挟角θ2より小さく、しかも、上記中央領域の導光体から離れるにしたがって徐々に小さくなる、
ことを特徴とする導光板の出光光場を導正する構造。 - 前記出光面の導光体が相互に平行に形成されることを特徴とする請求項1に記載の導光板の出光光場を導正する構造。
