立体映像信号生成回路に入力された左目映像 1 0は、 A Dコンバータ 2 0によって デジタル化されて、 左目映像用フレームメモリ 3 0に記録される。 同様に、 入力され た右目映像 1 1は A Dコンバータ 2 1によってデジタル化されて、 右目映像用フ レー ムメモリ 3 1 に記録される。 また、 A Dコンバータ 2 0、 2 1には切換制御部 4 1か ら A D変換のためのクロ ック信号 2 2が入力されている。  The left-eye video 10 input to the stereoscopic video signal generation circuit is digitized by the AD converter 20 and recorded in the left-eye video frame memory 30. Similarly, the input right-eye image 11 is digitized by the AD converter 21 and recorded in the right-eye image frame memory 31. A clock signal 22 for AD conversion is input from the switching control section 41 to the AD converters 20 and 21.

The signal switch 40 switches the left-eye video and the right-eye video and reads them out, thereby recording the composite stereoscopic video in the composite frame memory 50 and generating a composite stereoscopic video signal. The signal switch 40 is a switch (semiconductor switching element) that operates according to a timing signal instructed by the switching control section 41. The stereoscopic video signal generation circuit according to the present embodiment generates a composite stereoscopic video signal in which the left-eye video 10 and the right-eye video 11 are synthesized for each horizontal line from the left-eye video 10 and the right-eye video 11. I do. That is, in the case of the interlace method, the image is displayed every other scanning line, so that the signal switching unit 40 uses the signal switch 40 for each field (for example, the NTSC vertical synchronization timer). At the timing of 16.683 (milliseconds), the composite frame memory 50 ί Replace the video signal to be written. On the other hand, in the case of the non-interlaced method, since the scanning lines are displayed in order, the left-eye image and the right-eye image are displayed every other scanning line. The video signal to be written to the composite frame memory 50 is switched every 6 3 6 5 5 5 5 s by the NTSC horizontal synchronization timing.
この合成フレームメモリ 5 0に書き込むための右目映像データを右目映像用フ レー ムメモリ 3 1から読み出すタイ ミングは、 読み出しタイ ミング制御部 3 2によって制 御されている。 読み出しタイ ミング制御部 3 2には、 C P情報 1 3、 切換制御部 4 1 からの信号切り換器 4 0のタイ ミング信号、 画面サイズ情報及び立 ί本度調整信号が入 力される。 読み出しタイ ミング制御部 3 2では、 これらの情報から右目映像用フ レー ムメモリ 3 1から読み出すタイ ミ ングを算出し、 右目映像用フ レームメモ リ 3 1から のデータの読み出しクロ ックを発生して、 右目用映像を正規のタイ ミ ングから遅れて (又は、 早めて） 読み出すことによって、 適切な立体感が得られる視差量を与えるタ イ ミングを調整する。 すなわち、 右目映像用フレームメモリ 3 1 からの右目信号の読 み出しタイ ミングを、 C Ρ情報 1 3及び画面サイズ情報によって、 左目信号の読み出 しタイ ミングに対して制御して、 立体感が最適になるタイ ミ ングで読み出されるよう にしている。  The timing for reading the right-eye video data to be written to the composite frame memory 50 from the right-eye video frame memory 31 is controlled by the read timing control unit 32. The read timing controller 32 receives the CP information 13, the timing signal of the signal switch 40 from the switching controller 41, the screen size information, and the normality adjustment signal. The read timing control unit 32 calculates the timing to read from the right-eye video frame memory 31 from these information, and generates a clock to read data from the right-eye video frame memory 31. By adjusting the timing that gives the amount of parallax that provides an appropriate stereoscopic effect, by reading out the right-eye image later (or earlier) than the normal timing. That is, the reading timing of the right-eye signal from the right-eye video frame memory 31 is controlled with respect to the reading timing of the left-eye signal based on the CΡ information 13 and the screen size information, so that the stereoscopic effect is obtained. Reading is performed at the optimal timing.
切換制御部 4 1は、 信号切り換器 4 0を制御するもので、 同期信号発生器 7 0から 入力される水平同期信号 7 1、 垂直同期信号 7 2、 ドッ ト同期信号 7 3及び左右基準 信号 7 4に基づいて信号切り換器 4 0の動作を制御する。すなわち、前述したように、 どのようなタイ ミングで信号切り換器 4 0を切り換えて、 合成立体映像信号を生成す るために映像データの合成フレームメモリ 5 0への書き込みタイ ミングを設定する。 同期信号発生部 7 0は、 立体映像信号生成回路の外部 （例えば、 ディスプレイ コン トローラ） から入力された映像同期信号 8 2に基づいて水平同期信号 7 1及び垂直同 期信号 7 2を生成する。 また、 外部から入力された ドッ トサンプリ ング信号 8 3に基 づいて ドッ ト同期信号 7 3を生成する。 また、 映像同期信号 8 2に基づいて左右基準 信号 7 4を生成する。 この左右基準信号 7 4は、 ビデオ信号などの一般的な映像信号 を用いて立体映像信号を表示し伝送する場合、 映像信号が左の映像のものか、 右の映 像のものかを識別するための信号であり、 切換制御部 4 1に入力される他、 立体映像 信号生成回路の外部に対して出力される。 The switching control section 41 controls the signal switch 40, and outputs a horizontal synchronization signal 71, a vertical synchronization signal 72, a dot synchronization signal 73, and a left / right reference signal inputted from the synchronization signal generator 70. The operation of the signal switch 40 is controlled based on the signal 74. That is, as described above, the timing at which the signal switch 40 is switched at any timing and the timing at which the video data is written to the composite frame memory 50 is set in order to generate a composite stereoscopic video signal. The synchronizing signal generator 70 generates a horizontal synchronizing signal 71 and a vertical synchronizing signal 72 based on a video synchronizing signal 82 input from outside of the stereoscopic video signal generating circuit (for example, a display controller). Further, it generates a dot synchronization signal 73 based on the dot sampling signal 83 input from the outside. Further, a left and right reference signal 74 is generated based on the video synchronization signal 82. The left and right reference signals 74 are common video signals such as video signals. Is used to display and transmit a stereoscopic video signal using a signal for identifying whether the video signal is for a left video or a right video, and is input to the switching control unit 41, Output to the outside of the stereoscopic video signal generation circuit.
D Aコンバータ 6 0は、 デジタル化された映像信号をアナログ信号に変換して、 合 成立体映像信号と して出力する。  The DA converter 60 converts the digitized video signal into an analog signal and outputs it as a composite stereoscopic video signal.
なお、 前述した実施の形態では、 C P情報 1 3及び画面サイズ情報によって、 右目 映像データの読み出しタイ ミ ングを制御して適切な立体感が得られるよ うにしたが、 C Pまでの距離が無限大である （C P情報 1 3がない） 場合でも画面サイズ情報に応 じて、 右目映像データの読み出しタイ ミングを制御して、 視差量を調整することがで さる。  In the above-described embodiment, the right eye video data readout timing is controlled based on the CP information 13 and the screen size information so that an appropriate stereoscopic effect can be obtained. However, the distance to the CP is infinite. Even if there is no CP information 13, it is possible to adjust the amount of parallax by controlling the read timing of the right-eye video data according to the screen size information.
また、 前述した立体映像信号生成回路に供給される立体映像信号は、 左右一対の力 メラ （レンズ及び撮像素子） を有した立体映像撮影装置を用いて、 左右の映像記録と 同時に左右撮像素子の間隔 （眼間距離） 及び左目映像用カメ ラの光軸と右目映像用力 メラの光軸との交差点 （ク ロスポイン ト） までの距離をク ロスポイント情報と して記 録する機能を備えた立体映像撮影装置によって記録される。 すなわち、 該立体映像撮 影装置は、 立体映像と共に立体感に関するデータを記録している。  In addition, the stereoscopic video signal supplied to the above-described stereoscopic video signal generation circuit is transmitted to the left and right imaging elements simultaneously with the left and right video recording using a stereoscopic imaging apparatus having a pair of right and left power lenses (lens and imaging element). A 3D object with the function of recording the distance (interocular distance) and the distance to the intersection (crosspoint) between the optical axis of the left-eye image camera and the optical axis of the right-eye image camera as crosspoint information. Recorded by the video shooting device. That is, the three-dimensional image capturing apparatus records data relating to the three-dimensional effect together with the three-dimensional image.
さらに、 前述した立体映像信号生成回路に供給される立体映像信号を、 左右一対映 像をコンピュータグラフィ ック （C G ) で制作する機能を有する立体映像制作装置を 用いて、左右の映像記録と共に左右眼間距離と左右映像の光学上のクロスポイン ト（左 右視線の交差する点） までの距離をクロスポイン ト情報と して記録する機能を備えた 立体映像制作装置によって生成される。 すなわち、 該立体映制作装置は、 立体 C G映 像と共に立体感に関するデータを生成し記録している。  In addition, the stereoscopic video signal supplied to the stereoscopic video signal generation circuit described above is produced by using a stereoscopic video production device that has the function of producing a pair of left and right video images using computer graphics (CG). It is generated by a stereoscopic video production device equipped with a function that records the interocular distance and the distance to the optical crosspoint (the point where the left and right lines of sight intersect) of the left and right images as crosspoint information. That is, the stereoscopic picture production apparatus generates and records data relating to the stereoscopic effect together with the stereoscopic CG image.
図 7から図 9は、 本発明の実施の形態における、 左右映像の相対位置の変化による 立体度の調整を説明する図である。  FIG. 7 to FIG. 9 are diagrams illustrating the adjustment of the stereoscopic degree by changing the relative positions of the left and right images in the embodiment of the present invention.
図 7は、 右目映像と左目映像とが撮影時の位置にある場合を示す。  FIG. 7 shows a case where the right-eye image and the left-eye image are at the positions at the time of shooting.
ォリ ジナル立体映像 3 0 0は、 左目映像 3 0 1 と右目映像 3 ◦ 2 とによつて構成さ れている。 この状態では、 左目映像 3 0 1 と右目映像 3 0 2 との位置は撮影時と等し い位置にあり、 左右映像の相対位置が正しく再現されている。 よって、 ク ロスポイ ン ト 3 0 3は撮影時 （オリ ジナルク ロスポイン ト） の位置にある。 The original stereoscopic image 300 is composed of a left-eye image 301 and a right-eye image 3 2. In this state, the positions of the left-eye image 301 and the right-eye image 302 are the same as when shooting. And the relative position of the left and right images is correctly reproduced. Therefore, the cross point 303 is in the position at the time of shooting (original cross point).
図 8は、 右目映像を右側にずらして表示した状態を示す。  FIG. 8 shows a state in which the right-eye image is displayed shifted to the right.
立体映像 3 1 0は、 左目映像 3 1 1 と右目映像 3 1 2 とによつて構成されている。 左目映像の読み込みタイ ミングに対して、 右目映像の読み込みタイ ミングを遅く して (右目信号の位相を遅らせて）、左目映像に対して右目映像を右側にずらすオフせッ ト を設定して表示した場合、 左目で左目映像を見た視線と、 右目で右目映像を見た視線 とは表示画面の奥側で交差して、 クロスポイン ト 3 1 3が撮影時の位置よ り遠方に移 動する。 よって、 オリ ジナル立体映像より も、 飛び出し度が弱ま り、 奥行き感が強調 され、 '全体に遠方に遠ざかった映像となる。  The stereoscopic image 310 is composed of a left-eye image 311 and a right-eye image 312. Delays the reading timing of the right-eye image (delays the phase of the right-eye signal) with respect to the reading timing of the left-eye image, and sets and displays an offset to shift the right-eye image to the right with respect to the left-eye image In this case, the line of sight looking at the left eye image with the left eye and the line of sight looking at the right eye image with the right eye intersect at the far side of the display screen, and the cross point 3 13 moves farther from the shooting position. I do. Therefore, the degree of protrusion is weaker than that of the original stereoscopic image, and the sense of depth is emphasized.
図 9は、 右目映像を左側にずら して表示した状態を示す。  Figure 9 shows a state where the right-eye image is displayed shifted to the left.
立体映像 3 2 0は、 左目映像 3 2 1 と右目映像 3 2 2 とによつて構成されている。 左目映像の読み込みタイ ミングに対して、 右目映像の読み込みタイ ミングを早く して (右目信号の位相を進めて）、左目映像に対して右目映像を左側にずらすオフセッ トを 設定して表示した場合、 左目で左目映像を見た視線と、 右目で右目映像を見た視線と は表示画面の手前側で交差して、 ク ロスポイン ト 3 2 3が撮影時の位置よ り手前とな る。 よって、 オリ ジナル立体映像よ り も、 飛び出し度が強調され、 奥行き感が弱ま り、 全体に手前に近づいた映像となる。  The three-dimensional image 320 is composed of a left-eye image 3221 and a right-eye image 3222. When the reading timing of the right-eye image is advanced (leading the phase of the right-eye signal) to the timing of reading the left-eye image, and an offset is set to shift the right-eye image to the left with respect to the left-eye image. In addition, the line of sight of the left eye with the left eye and the line of sight of the right eye with the right eye intersect on the near side of the display screen, and the cross point 3 23 3 is closer to the position at the time of shooting. Therefore, compared to the original stereoscopic image, the degree of protrusion is emphasized, the sense of depth is weakened, and the image becomes closer to the front as a whole.
なお、 オフセッ トを設定して左眼映像と右眼映像とを表示したときに、 左右眼映像 の左右端部の各々一方が欠けるが、 この映像が不足する領域の近傍の映像を横方向に 拡大して表示するとよい。 このとき、 表示画面の縦横比 （ァスぺク ト比） に基づいて、 映像を縦方向にも拡大して表示する。 具体的には、 4に示すオフセッ ト状態では、 右 眼映像の左端が欠けるが、 右眼映像の左端の映像を表示画面の左端部まで伸長して右 眼映像を表示する。 また、 図 9に示すオフセッ ト状態では、 右眼映像の右端が欠ける が、 右眼映像の右端の映像を表示画面の右端部まで伸長して右眼映像を表示する。 こ れらのオフセッ ト した映像の側部を伸長すると ともに、 表示画面のァスぺク ト比で側 部の映像を縦方向にも伸長して、 映像を拡大して表示することによって、 表示画面か らオフセッ ト した映像が欠落して、 何も映像が表示されない領域 （黒色に表示される 領域） を生じさせることがなく、 自然な立体映像を表示することができる。 When an offset is set and the left-eye image and the right-eye image are displayed, one of the left and right ends of the left- and right-eye images is missing. It is good to enlarge and display. At this time, the image is enlarged and displayed in the vertical direction based on the aspect ratio of the display screen (aspect ratio). Specifically, in the offset state shown in 4, the left end of the right-eye image is missing, but the left-end image of the right-eye image is extended to the left end of the display screen to display the right-eye image. Also, in the offset state shown in FIG. 9, the right end of the right eye image is missing, but the right end image of the right eye image is extended to the right end of the display screen to display the right eye image. By expanding the side of these offset images, and also expanding the side images vertically by the aspect ratio of the display screen, the image is enlarged and displayed. Screen It is possible to display a natural 3D image without causing the image that is offset from the image to be lost and creating a region where no image is displayed (a region displayed in black).
次に、 左右眼映像のオフセッ ト量の算出について説明する。  Next, the calculation of the offset amount of the left and right eye images will be described.
図 1 0は、 オリ ジナル立体映像の視差量と立体像出現位置との関係を示す。 オリ ジ ナル立体映像 3 0 0においては、 図 1 0に示すよ うに右目映像と左目映像とが撮影時 の位置関係にある。 このとき、 立体像出現位置 （立体像の見える位置と観察者との間 の距離） を L d、 視距離 （観察者と表示画面との間の距離） を L s 、 表示画面上に表 示される左眼映像と右眼映像との視差量を X 1、 眼間距離を d e (約 6 5 mm) とす ると、 上記パラメータは図 1 0に示す式 （ 1 ) によって表される。 そして、 立体像出 現位置 L dは、 この式を解く ことによって、 視差量 X 1 の関数と して求めることがで きる。 ここで X I は、 表示画面の大きさによって （表示画面サイズに比例して） 変化 する。  FIG. 10 shows the relationship between the amount of parallax of the original stereoscopic video and the appearance position of the stereoscopic image. In the original three-dimensional image 300, the right-eye image and the left-eye image have a positional relationship at the time of shooting as shown in FIG. At this time, the appearance position of the stereoscopic image (the distance between the position where the stereoscopic image can be viewed and the observer) is displayed on the display screen as L d, the viewing distance (the distance between the observer and the display screen) as L s. Assuming that the amount of parallax between the left-eye image and the right-eye image is X1 and the interocular distance is de (approximately 65 mm), the above parameters are expressed by equation (1) shown in FIG. Then, the stereoscopic image appearance position L d can be obtained as a function of the amount of parallax X 1 by solving this equation. Here, XI varies depending on the size of the display screen (in proportion to the display screen size).
図 1 1 は、 左右眼画像にオフセッ トを与えた場合の左右眼映像の視差量と立体像出 現位置との関係を示す。 このとき、 立体像出現位置 （立体像の見える位置と観察者と の間の距離） を L d、 視距離 （観察者と表示画面との間の距離） を L s、 左右眼映像 のオフセッ ト量を X o、 表示画面上に表示される左眼映像と右眼映像との視差量を X 1、 眼間距離を d e (約 6 5 mm) とすると、 上記パラメータは図 1 1に示す式 （ 2 ) によって表される。そして、オリ ジナル映像と同じ立体像出現位置 L dを得るために、 図 1 0に示す式 （ 1 ) によって求めた L dを式 （ 2 ) に代入する。 そして、 左右眼映 像のオフセッ ト量を X oを求める。  Figure 11 shows the relationship between the amount of parallax between left and right eye images and the stereoscopic image appearance position when an offset is given to the left and right eye images. At this time, the appearance position of the stereoscopic image (the distance between the position where the stereoscopic image can be viewed and the observer) is L d, the viewing distance (the distance between the observer and the display screen) is L s, and the offset of the left and right eye images If the amount is X o, the amount of parallax between the left and right eye images displayed on the display screen is X 1, and the interocular distance is de (approximately 65 mm), the above parameters are expressed by the equations shown in Fig. 11. (2). Then, in order to obtain the same stereoscopic image appearance position Ld as that of the original video, the Ld obtained by equation (1) shown in FIG. 10 is substituted into equation (2). Then, Xo is obtained as the offset amount of the left and right eye images.
図 1 2乃至図 1 7は、 本発明の実施の形態の立体映像表示装置の構成図である。 表示手段 1 2 1は液晶を用いた表示装置によって構成されており、 図 1 2及び図 1 3に示すように、 平面光源 5の発光面左右に偏光方向が直交する右眼用偏光フィルタ 部 6 a と、 左眼用偏光フィルタ部 6 b とを配置している。 なお、 発光素子と偏光フィ ルタを用いなくても、 異なる偏光の光を異なる位置から照射するよ うに構成すればよ く、 例えば、 異なる偏光の光を発生する発光素子を二つ設けて、 異なる偏光の光を異 なる位置からフ レネルレンズ 3に照射するよ うに構成してもよい。 また、 本形態例において 3はフレネルレンズであり、 各フィルタ部 6 a , 6 b を通 過した各光は、 このフ レネルレンズ 3で平行光と して液晶表示素子 2に照射される。 そして本実施形態例では液晶表示素子 2の表示パネル 2 a は、 図 1 4に示すよ う に、 立体視される第一及び第二の画像を構成する画素 （L、 R ) を平面的に交互に配置さ れる市松模様をなすよ うに配置するものと している。 そして、 この表示パネルの光源 側及び観察者側の両面にはそれぞれ偏光パネル 2 b , 2 cが貼付されている。 FIGS. 12 to 17 are configuration diagrams of the stereoscopic video display device according to the embodiment of the present invention. The display means 121 is constituted by a display device using a liquid crystal, and as shown in FIGS. 12 and 13, the right-eye polarization filter unit 6 whose polarization direction is orthogonal to the left and right of the light emitting surface of the flat light source 5. a and the left-eye polarization filter unit 6 b. It should be noted that the light emitting element and the polarizing filter may not be used, and the light having different polarization may be irradiated from different positions.For example, two light emitting elements that generate light of different polarizations may be provided and different. The configuration may be such that polarized light is applied to the Fresnel lens 3 from different positions. Further, in the present embodiment, reference numeral 3 denotes a Fresnel lens, and each light passing through each of the filter sections 6a and 6b is applied to the liquid crystal display element 2 as parallel light by the Fresnel lens 3. In the present embodiment, the display panel 2a of the liquid crystal display element 2 is arranged such that, as shown in FIG. 14, pixels (L, R) constituting the first and second images viewed in a stereoscopic manner are two-dimensionally displayed. They are arranged in a checkered pattern that is alternately arranged. Polarizing panels 2b and 2c are attached to both sides of the display panel on the light source side and the observer side, respectively.
本形態例では、 液晶表示パネル 2は、 2枚の透明板（例えば、 ガラス板）の間に所定 の角度（例えば 9 0度）ねじれて配向された液晶が配置されており、 例えば、 T F T型 の液晶表示パネルを構成している。 液晶表示パネルに入射した光は、 液晶に電圧が加 わっていない状態では、 入射光の偏光が 9 0度ずらして出射される。 一方、 液晶に電 圧が加わっている状態では、 液晶のねじれが解けるので、 入射光はそのままの偏光で 出射される。  In the present embodiment, the liquid crystal display panel 2 has a liquid crystal that is twisted and oriented at a predetermined angle (for example, 90 degrees) between two transparent plates (for example, glass plates). Of the liquid crystal display panel. In the state where no voltage is applied to the liquid crystal, the light incident on the liquid crystal display panel is emitted with the polarization of the incident light shifted by 90 degrees. On the other hand, when a voltage is applied to the liquid crystal, the liquid crystal is untwisted, and the incident light is emitted with the same polarization.
そして、 本形態例では、 表示パネル 2の光源側に市松状フィルタ 7が貼付されてい る。  In this embodiment, a checkered filter 7 is attached to the light source side of the display panel 2.
即ち、 偏光フィルタ 6 を透過した光はフレネルレンズ 3 に照射され、 フ レネノレレン ズ 3では光源 5から拡散するよ うに放射された光の光路を略平行になり市松状フィル タを透過して、 液晶表示パネル 2に照射される。  That is, the light transmitted through the polarizing filter 6 is applied to the Fresnel lens 3, and the light path of the light radiated from the light source 5 in the Fresnel lens 3 is made substantially parallel so that the light passes through the checkered filter and becomes liquid crystal. The display panel 2 is irradiated.
このとき、 市松状フィルタ 7から照射される光は、 上下方向に広がることがないよ うに出射され、 液晶表示パネル 2に照射される。 すなわち、 市松状フィルタ 7の特定 の領域を透過した光が、 液晶表示パネル 2の特定表示単位の部分を透過するよ うにな つている  At this time, the light emitted from the checkered filter 7 is emitted so as not to spread in the vertical direction, and is emitted to the liquid crystal display panel 2. That is, light transmitted through a specific area of the checkered filter 7 is transmitted through a specific display unit of the liquid crystal display panel 2.
また、 液晶表示パネルに照射される光のうち、 偏光フィルタ 6の右側偏光フィルタ 部 aを通過した光と左側偏光フィルタ部 bを通過した光とは、 異なる角度でフ レネル レンズ 3に入射し、 フレネルレンズ 3で屈折して左右異なる経路で液晶表示パネル 2 から放射される。  Also, of the light applied to the liquid crystal display panel, the light that has passed through the right polarizing filter part a and the light that has passed through the left polarizing filter part b of the polarizing filter 6 enter the Fresnel lens 3 at different angles, The light is refracted by the Fresnel lens 3 and is radiated from the liquid crystal display panel 2 through different paths.
市松状フィルタ 7は、 透過する光の位相を変える領域が、 図 1 5 ( 1 ) に示すよ う に微細な間隔の市松状模様で繰り返して配置されている。 具体的には、 図 1 5 ( 2 ) に示すよ うに光透過性の基材 1 7 1 に、 微細な幅の 1 2波長板 1 7 2が設けられた 領域 7 a と、 1 / 2波長板 1 7 2の幅と同一の微細な間隔で、 1 / 2波長板 1 7 2が 設けられていない領域 7 b とが微細な間隔で繰り返して設けられた列が位相をずら し て設けられている。 なお、 この 1 Z 2波長板は光源側に設けても、 表示パネル側に設 けても差し支えない。 The checkerboard filter 7 has areas in which the phase of transmitted light is changed repeatedly arranged in a checkerboard pattern at fine intervals as shown in FIG. 15 (1). Specifically, Fig. 15 (2) As shown in the figure, the area 7a where the 12-wavelength plate 172 with a fine width is provided on the light-transmitting substrate 171, and the fine A row in which a half-wave plate 172 in which the half-wave plate 172 is not provided is repeatedly provided at a fine interval and the phase is shifted. Note that the 1Z2 wavelength plate may be provided on the light source side or on the display panel side.
このよ うな構成によ り、 設けられた 1 / 2波長板 1 7 2によって透過する光の位相 を変える領域 7 a と、 1ノ 2波長板 1 7 2が設けられていないために透過する光の位 相を変えない領域 7 b とが微細な間隔の巿松模様と して規則的に設けられているもの である。 1 / 2波長板は、 透過する光の位相を変化させる位相差板と して機能する。 1 / 2波長板 1 7 2は、 その光学軸を偏光フィルタ 6の右側偏光ブイルタ部 aを透過 する光の偏光軸と 4 5度傾けて配置して、 右側偏光フィルタ部 aを透過した光の偏光 軸を 9 0度回転させて出射する。 すなわち、 右側偏光フィルタ部 aを透過した光の偏 光軸を 9 0度回転させて、 左側偏光フィルタ部 bを透過する光の偏光と等しくする。 すなわち、 1ノ 2波長板 7 2が設けられていない領域 7 b は左側偏光フィルタ部 b を 通過した、 偏光板 2 b と同一の偏光を有する光を透過し、 1 2波長板 7 2が設けら れた領域 7 a は右側偏光フィルタ部 a を通過した、 偏光板 2 1 と偏光軸が直交した光 を、 偏光板 2 bの偏光軸と等しく なるよ うに回転させて出射する。  With such a configuration, the area 7a for changing the phase of the light transmitted by the provided half-wave plate 172 and the light transmitted by the absence of the 1-wavelength plate 172 are provided. The region 7b in which the phase of the above does not change is regularly provided as a fine pine pattern at a fine interval. The half-wave plate functions as a phase difference plate that changes the phase of transmitted light. The half-wave plate 1 72 is arranged such that its optical axis is tilted by 45 degrees with respect to the polarization axis of the light passing through the right-hand polarizing filter section a of the polarizing filter 6 so that the light passing through the right-hand polarizing filter section a The light is emitted with the polarization axis rotated 90 degrees. That is, the polarization axis of the light transmitted through the right-side polarization filter section a is rotated by 90 degrees to be equal to the polarization of the light transmitted through the left-side polarization filter section b. That is, the region 7b where the 1-wavelength plate 72 is not provided transmits light having the same polarization as the polarizing plate 2b that has passed through the left-side polarization filter portion b, and the 12-wavelength plate 72 is provided. The separated area 7a emits the light that has passed through the right-hand polarization filter section a and whose polarization axis is orthogonal to the polarization plate 21 so as to be rotated so as to be equal to the polarization axis of the polarization plate 2b.
この市松状フィルタ 7の偏光特性の繰り返しは、 液晶表示パネル 2の表示単位と同 一のピッチと して、 表示単位毎（すなわち、 表示単位の横方向の水平ライン及び縦方向 の垂直ライン）に透過する光の偏光が異なるよ うにする。 よって、 液晶表示パネル 2の 走査方向と副走査方向の表示単位毎に対応する微細位相差板の偏光特性が異なるよ う になって、 隣り合う画素毎に出射する光の方向が異なる。  The repetition of the polarization characteristic of the checkered filter 7 is performed at the same pitch as the display unit of the liquid crystal display panel 2 for each display unit (that is, the horizontal horizontal line and the vertical vertical line of the display unit). The transmitted light is polarized differently. Therefore, the polarization characteristics of the fine phase difference plate corresponding to each display unit in the scanning direction and the sub-scanning direction of the liquid crystal display panel 2 are different, and the direction of the emitted light is different for each adjacent pixel.
なお、 本発明では、 市松状フィルタ 7の偏光特性の繰り返しは、 液晶表示パネル 2 の表示単位のピツチに対する整数倍のピツチと して、 巿松状フィルタ 7の偏光特性が 複数の表示単位毎（すなわち、 複数の表示単位の毎）に変わるよ うにしてもよい。 このよ うに、 微細位相差板の偏光特性の繰り返し毎に異なる光を液晶表示パネル 2 の表示素子に照射する必要があるため、 市松状フィルタ 7を透過して液晶表示パネル 2に照射される光は、 上下方向の拡散を抑制したものである必要がある。 すなわち、 市松状フィルタ 7の光の位相を変化させる領域 7 aは、 偏光フィルタ 6 の右側偏光フィルタ部 aを透過した光を、 左側偏光フィルタ部 bを透過した光の偏光 と等しく して透過する。 また、 市松状フィルタ 7の光の位相を変化させない領域 7 b は、 偏光フィルタ 6の左側偏光フィルタ部 b を透過した光をそのまま透過する。 そし て市松状フィルタ 7を出射した光は、 左側偏光フィルタ部 b を透過した光と同じ偏光 を有して、 液晶表示パネル 2の光源側に設けられた偏光板 2 bに入射する。 In the present invention, the repetition of the polarization characteristic of the checkered filter 7 is a pitch that is an integral multiple of the pitch of the display unit of the liquid crystal display panel 2. That is, the display unit may be changed to a plurality of display units. As described above, it is necessary to irradiate the display element of the liquid crystal display panel 2 with different light every time the polarization characteristic of the fine phase difference plate is repeated. The light applied to 2 needs to suppress the diffusion in the vertical direction. That is, the area 7a of the checker filter 7 that changes the phase of light transmits the light transmitted through the right-side polarization filter section a of the polarization filter 6 in a manner equal to the polarization of the light transmitted through the left-side polarization filter section b. . The area 7 b of the checkered filter 7 in which the phase of the light does not change transmits the light transmitted through the left-side polarization filter part b of the polarization filter 6 as it is. Then, the light emitted from the checkered filter 7 has the same polarization as the light transmitted through the left polarizing filter part b, and enters the polarizing plate 2 b provided on the light source side of the liquid crystal display panel 2.
偏光板 2 bは第 2偏光板と して機能し、 巿松状フィルタ 7を透過した光と同一の偏光 の光を透過する偏光特性を有する。 すなわち、 偏光フィルタ 6の左側偏光フィルタ部 b を透過した光は第 2偏光板 2 c を透過し、 偏光フィルタ 6の右側偏光フィルタ部 a を透過した光は偏光軸を 9 0度回転させられて第 2偏光板 2 bを透過する。 また、 偏 光板 2 cは第 1偏光板と して機能し、 偏光板 2 1 と 9 0度異なる偏光の光を透過する 偏光特性を有する。 The polarizing plate 2b functions as a second polarizing plate, and has a polarization characteristic of transmitting the same polarized light as the light transmitted through the pine filter 7. That is, the light transmitted through the left polarizing filter portion b of the polarizing filter 6 transmits through the second polarizing plate 2c, and the light transmitted through the right polarizing filter portion a of the polarizing filter 6 has its polarization axis rotated 90 degrees.
