Description

また、光変調層に電場を発生させていないときは、液晶性分子314bの光軸Ax2は透明基板311,318の表面と直交している。一方、液晶性モノマー314aは、図7(A),(B)に示されるように、光変調層314の電場の有無に関わらず、液晶性モノマー314aの光軸Ax1は透明基板311,318の表面と直交するような構造となる。なお、光軸Ax2は常に透明基板311,318の表面と完全に直交している必要はなく、例えば、製造誤差等によって透明基板311,318の表面と90度以外の角度で交差していてもよい。また、光軸Ax1が常に透明基板311,318の表面と完全に直交している必要はなく、例えば、製造誤差等によって透明基板311,318の表面と90度以外の角度で交差していてもよい。 When no electric field is generated in the light modulation layer, the optical axis Ax2 of the liquid crystal molecules 314b is orthogonal to the surfaces of the transparent substrates 311 and 318. On the other hand, as shown in FIGS. 7A and 7B, the liquid crystal monomer 314a has the optical axis Ax1 of the liquid crystal monomer 314a of the transparent substrates 311 and 318 regardless of the presence or absence of the electric field of the light modulation layer 314. The structure is orthogonal to the surface. The optical axis Ax2 does not always need to be completely orthogonal to the surfaces of the transparent substrates 311 and 318. For example, even if the optical axis Ax2 intersects the surfaces of the transparent substrates 311 and 318 at an angle other than 90 degrees due to manufacturing errors or the like. Good. Further, the optical axis Ax1 does not always need to be completely orthogonal to the surfaces of the transparent substrates 311 and 318. For example, even if the optical axis Ax1 intersects the surfaces of the transparent substrates 311 and 318 at an angle other than 90 degrees due to a manufacturing error or the like. Good.

なお、電場によって透過状態から散乱状態へと遷移するタイプ(ここでは「ノーマリー透明」とする)を示したが、電場によって散乱状態から透過状態へと遷移するタイプ(ここでは「ノーマリー散乱」とする)でもよい。また、導光体310としては、サイドライト光源302から出射された光が面状内部から全体もしくは部分的に入射させる機能があればよく、透過・散乱だけではなく、回折、屈折などの光学現象を利用することができる。しかしながら、ディスプレイ用照明装置の応用を考えた場合では、入射された光を遠くまで導光させ、効率よく導光体310から発光させるという観点において、ノーマリー透明タイプの導光体が好ましい。以下、ノーマリー透明タイプの導光体を用いて説明する。 In addition, although the type which makes a transition from a transmission state to a scattering state by an electric field (here, “normally transparent”) is shown, the type which makes a transition from a scattering state to a transmission state by an electric field (here, “normally scattering”). ) The light guide 310 only needs to have a function of allowing the light emitted from the sidelight light source 302 to be incident in whole or in part from the inside of the planar shape. Can be used. However, in the case of considering the application of a display lighting device, a normally transparent light guide is preferable from the viewpoint of guiding incident light far and efficiently emitting light from the light guide 310. Hereinafter, description will be made using a normally transparent light guide.
