Abstract

　本発明による液晶表示装置（１００）は、透過状態と散乱状態とを取り得る散乱型液晶層（１４０）を含む散乱液晶パネル（１１０）と、再帰性反射板（１５０）とを備える。再帰性反射板（１５０）と組み合わせる前の散乱液晶パネル（１１０）は、散乱液晶パネル（１１０）の背面（１１０ｂ）から入射し前面（１１０ａ）から出射する光のうち前面（１１０ａ）の法線方向からの角度が０度から１０度までの範囲で出射する光の散乱強度の平均値をＩ0-10と表し、２０度から３０度までの範囲で出射する光の散乱強度の平均値をＩ20-30と表すと、０．４５≦ｌｏｇ（Ｉ0-10／Ｉ20-30）≦１．４８の関係を満たす。
