Between the picture elements of the display panel, signal lines are provided for giving image data to the picture elements. In addition, a light shielding area is provided around each picture element to prevent unnecessary transmitted light. The widths of these signal lines and light shielding regions hardly depend on the shape of the picture element, and a certain width is required. The signal lines and the light shielding regions do not contribute as openings. Therefore, when the picture element shape is extremely long, the ratio of the area of the signal line and the width of the light shielding area is relatively increased, and the aperture ratio is significantly reduced. Further, the width of the light shielding portion of the parallax barrier is designed to be slightly wider than the horizontal pixel pitch.

Shi However, if the picture element shape is extremely long, the ratio of the light shielding part to the transmission part of the parallax barrier becomes relatively large, so that the area of the transmission part decreases.

[0002] 従来の、マトリクス状に絵素が配置されたデュアルビューパネルと視差バリアとを組 み合わせたデュアルビューディスプレイでは、表示画面を右側から観察する観察者 の観察方向である右観察方向と、左側から観察する観察者の観察方向である左観 察方向とにそれぞれ異なる画像を表示することができる。この場合には、図 7 (a)に示 すように、各絵素を、右観察方向画像表示用 (右観察方向力 の観察者用)と左観察 方向画像表示用 (左観察方向からの観察者用)とに振り分ける。ここで、絵素とは、各 色 (R (赤), B (青), G (緑))を表示させる最小単位を指すものとする。図 7 (a)では、 各絵素は、図面向力つて左から、右観察方向画像表示用の Rの絵素(以後 Rrとする )、左観察方向画像表示用の Gの絵素(以後 G1とする)、右観察方向画像表示用の B の絵素 (以後 Brとする)、左観察方向画像表示用の Rの絵素 (以後 R1とする)、右観 察方向画像表示用の Gの絵素(以後 Grとする)、左観察方向画像表示用の Bの絵素 (以後 B1とする)のように配列されている。なお、図 7 (b)は、絵素が図 7 (a)の構成とな つて 、るデュアルビューディスプレイで用いられる視差バリア基板の構成を示すもの である。このような視差バリア基板が、図 8に示すように、絵素が配列された表示画面 の前に配置されると、図 9に示すように、右観察方向からの観察者からは Rr, Br, Gr が見え、左観察方向からの観察者からは Rl, Bl, G1が見える。  In a conventional dual view display in which a dual view panel in which picture elements are arranged in a matrix and a parallax barrier are combined, a right observation direction that is an observation direction of an observer observing the display screen from the right side In addition, different images can be displayed in the left observation direction, which is the observation direction of the observer observing from the left side. In this case, as shown in Fig. 7 (a), each picture element is displayed for right observation direction image display (for observers with right observation direction force) and left observation direction image display (from left observation direction). For the observer). Here, the picture element refers to the minimum unit for displaying each color (R (red), B (blue), G (green)). In Fig. 7 (a), each picture element is drawn from left to right with the R picture element for displaying the right observation direction image (hereinafter referred to as Rr) and the G picture element for displaying the left observation direction image (hereinafter referred to as Rr). G1), B picture element for right viewing direction image display (hereinafter referred to as Br), R picture element for left viewing direction image display (hereinafter referred to as R1), G for right viewing direction image display Picture elements (hereinafter referred to as Gr) and B picture elements (hereinafter referred to as B1) for displaying images in the left observation direction. FIG. 7 (b) shows the configuration of the parallax barrier substrate used in the dual view display in which the picture element has the configuration shown in FIG. 7 (a). When such a parallax barrier substrate is placed in front of a display screen on which picture elements are arranged as shown in FIG. 8, an observer from the right viewing direction will see Rr, Br as shown in FIG. , Gr can be seen, and Rl, Bl, G1 can be seen from the observer from the left direction.
[0003] しかし、従来のデュアルビューディスプレイでは、各絵素を右観察方向画像表示用 と左観察方向画像表示用とに振り分けるために、水平方向の精細度は、図 10に示す ような従来の単一表示ディスプレイの 1Z2になる。  [0003] However, in the conventional dual view display, since each picture element is divided into a right observation direction image display and a left observation direction image display, the horizontal definition is as shown in FIG. It becomes 1Z2 of a single display.
[0004] そこで、各観察方向からの表示を従来の単一表示ディスプレイと同じ精細度に保つ ために、単一表示ディスプレイの R, G, Bの 3絵素からなる画素の区画(図 10の点線 で囲まれた部分)の中に、 Rr, Gr, Br, Rl, Gl, Blの 6絵素を配置する必要がある。 従来のデュアルビューディスプレイにおける絵素配列でこれを実現するためには、図 11のように各絵素を左右に 2分割して、それぞれを、右観察方向画像表示用と左観 察方向画像表示用とに振り分ける必要がある。 [0004] Therefore, the display from each observation direction is maintained at the same definition as a conventional single display. Therefore, Rr, Gr, Br, Rl, Gl, Bl 6 are included in the pixel block consisting of the three picture elements R, G, B of the single display (the part surrounded by the dotted line in Fig. 10). It is necessary to arrange the picture elements. In order to achieve this with the picture element arrangement in the conventional dual view display, each picture element is divided into left and right as shown in Fig. 11, and each is used for right observation direction image display and left observation direction image display. It is necessary to distribute it for the purpose.
[0005] また、特許文献 1には、第 1方向用の絵素と第 2方向用の絵素とが行において交互 に、かつ、行毎に一つずらして配列されており、また、遮光部が格子状に設けられた デュアルビューディスプレイが開示されて 、る。 [0005] Further, in Patent Document 1, the first-direction picture elements and the second-direction picture elements are arranged alternately in the rows and shifted one by one in each row. A dual view display having a grid portion is disclosed.

発明が解決しょうとする課題  Problems to be solved by the invention
[0006] ここで、絵素を、上記のように左右 2分割した場合には、絵素の形状が極端に縦長 ( 列方向と行方向の比において列方向に長い)形状になる。そのため、以下のような問 題が発生する。 [0006] Here, when the picture element is divided into left and right as described above, the picture element has an extremely long shape (long in the column direction in the ratio of the column direction to the row direction). Therefore, the following problems occur.
[0007] まず 1つ目の問題として、ディスプレイの輝度が低下する。これは、次の理由による 。ディスプレイパネルの各絵素の間には、各絵素に画像データを与えるための信号 線が配置されている。また各絵素の周辺には不要な部分の透過光を防ぐために、遮 光領域が設けられている。これらの信号線や遮光領域の幅は絵素形状にはほとんど 依存せず一定の幅が必要であり、この信号線や遮光領域の幅の領域は開口部とし ては寄与しない。そこで、絵素形状が極端に縦長になることこで、信号線や遮光領域 の幅の領域の部分の面積の比率が相対的に上がり、開口率が著しく低下する。また 、視差バリアの遮光部の幅は水平方向の絵素ピッチよりも若干幅広く設計されている 。これはディスプレイデバイスと視差バリア基板の相対位置が若干ずれた場合や、最 適な観察方向からややずれた方向から画面を観察した場合でも、視差バリア基板 20 の遮光部が逆観察方向画像表示絵素からの透過光を遮光することができるようにす るためである。これによつて、各観察方向の画面の表示が、それぞれ逆の観察方向 の画面に移り込むことを防ぎ、良好なデュアルビュー表示画像を得ることができる。し かし、絵素形状が極端に縦長になると、視差バリアの透過部に対する遮光部の比率 が相対的に大きくなるため、透過部の面積が減少する。そのため、ディスプレイの輝 度が低下することになる。 [0007] First, as a first problem, the brightness of the display decreases. This is due to the following reasons. Between the picture elements of the display panel, signal lines are provided for giving image data to the picture elements. In addition, a light shielding area is provided around each picture element to prevent unnecessary transmitted light. The widths of these signal lines and light shielding regions hardly depend on the shape of the picture element, and a certain width is required. The signal lines and the light shielding regions do not contribute as openings. Therefore, when the picture element shape is extremely long, the ratio of the area of the signal line and the width of the light shielding area is relatively increased, and the aperture ratio is significantly reduced. Further, the width of the light shielding portion of the parallax barrier is designed to be slightly wider than the horizontal pixel pitch. This is because even if the relative position of the display device and the parallax barrier substrate is slightly deviated, or when the screen is observed from a direction slightly deviated from the optimal observation direction, the light shielding part of the parallax barrier substrate 20 is displayed in the reverse observation direction image display picture. This is because the transmitted light from the element can be shielded. As a result, it is possible to prevent the display on the screen in each observation direction from moving to the screen in the opposite observation direction, and obtain a good dual view display image. Shi However, if the picture element shape is extremely long, the ratio of the light shielding part to the transmission part of the parallax barrier becomes relatively large, so that the area of the transmission part decreases. As a result, the brightness of the display decreases.
[0008] また、 2つめの問題として、絵素を、上記のように左右 2分割した場合には、 CF (カラ 一フィルター)側のガラス基板を薄型化する必要があり、ガラス基板の強度が低下す る。これは、次の理由による。デュアルビュー表示の最適観察方向と水平方向(行方 向)の絵素ピッチには、以下の関係がある。  [0008] In addition, as a second problem, when the picture element is divided into left and right parts as described above, the glass substrate on the CF (color filter) side needs to be thinned, and the strength of the glass substrate is reduced. descend. This is due to the following reason. There is the following relationship between the optimal viewing direction of dual view display and the pixel pitch in the horizontal direction (in the horizontal direction).
[0009] tan ( 0 ) =l/ (2-d)  [0009] tan (0) = l / (2-d)
ここで、 Θ:ディスプレイ表面の法線方向と最適観察方向の成す角度  Where Θ is the angle between the normal direction of the display surface and the optimal viewing direction
1:水平方向の絵素ピッチ  1: Horizontal pixel pitch
d:ディスプレイデバイスと視差バリア間の距離  d: Distance between display device and parallax barrier
上記関係式から、図 11のように絵素を左右に 2分割すると、水平方向の絵素ピッチ 1 力 になるため、最適観察方向を保っためには、ディスプレイパネルと視差バリア 基板の距離 dも 1Z2にする必要がある。視差バリア基板はディスプレイパネルの視差 ノリア側のガラス基板 (CF側のガラス基板)上に貼り付けるため、 dを 1Z2にするため には、このガラス基板を薄膜ィ匕する必要がある。しかし、ガラスを薄膜ィ匕すると強度が 低下するため、ディスプレイパネルの製造プロセスでガラス基板の欠け、割れ、ムラ等 の問題が発生し、歩留まりの低下が起こる。  From the above relational expression, if the picture element is divided into left and right as shown in Fig. 11, the horizontal picture element pitch becomes 1 force, so the distance d between the display panel and the parallax barrier substrate is also used to maintain the optimum viewing direction. Need to be 1Z2. Since the parallax barrier substrate is affixed on the parallax-noria side glass substrate (CF-side glass substrate) of the display panel, it is necessary to thin the glass substrate in order to make d 1Z2. However, when the glass is thinned, the strength decreases, so that problems such as chipping, cracking and unevenness of the glass substrate occur in the manufacturing process of the display panel, resulting in a decrease in yield.
[0010] なお、図 14のように絵素を上下 2分割した場合には、図 10に示す単一表示ディス プレイの R, G, Bの 3絵素からなる区画の中に Rr、 Gl, Brまたは Rl, Gr, B1の 3種類 の絵素し力含まないため、各観察方向からの表示の精細度を上げる目的を果たすこ とにならない。  [0010] In addition, when the picture element is divided into upper and lower parts as shown in Fig. 14, the Rr, Gl, It does not fulfill the purpose of increasing the display definition from each observation direction because it does not include the three types of Br, Rl, Gr, and B1.
[0011] すなわち、図 14の構成では、 Rr、 Gr、 Brの組あるいは Rl、 Gl、 B1の組からなる 3原 色絵素は行方向 5絵素分の領域に渡つて配置されることになるため、行方向 3絵素 分の領域に 3原色絵素が配置されることになる図 10の構成と比較して、 3原色絵素の 配置される領域が行方向に広いことから、表示の精細度が低下することになる。  [0011] That is, in the configuration of FIG. 14, the three primary color picture elements composed of the combination of Rr, Gr, Br or the combination of Rl, Gl, B1 are arranged over the area of five picture elements in the row direction. Therefore, compared to the configuration shown in Fig. 10 in which the three primary color picture elements are arranged in the area of three picture elements in the row direction, the area in which the three primary color picture elements are arranged is wider in the row direction. The definition will be reduced.
[0012] また、第 1方向用の絵素と第 2方向用の絵素とが、 1つの行において交互に、かつ、 行毎に一つずらして配列されており、また、遮光部が格子状に設けられた従来のデュ アルビユーディスプレイでは、格子状に設けられた遮光部において、列方向、行方向 の両方に対して、光漏れを考慮する必要がある。この場合、遮光部の配置位置の誤 差を考慮して、広めに遮光部を設ける必要がある。よって、このような格子状の遮光 部を設けたディスプレイでは、開口率、および、コントラスト比等の低下が起きてしまう ことになる。 [0012] In addition, the first direction picture element and the second direction picture element are arranged alternately in one row and shifted by one for each row, and the light-shielding portion is a lattice. The conventional du In the Albi display, it is necessary to consider light leakage in both the column direction and the row direction in the light shielding portion provided in a lattice shape. In this case, it is necessary to provide a light shielding part wider in consideration of an error in the arrangement position of the light shielding part. Therefore, in a display provided with such a lattice-shaped light shielding portion, the aperture ratio, the contrast ratio, and the like are lowered.
[0013] 本発明は、上記の問題点に鑑みてなされたものであり、その目的は、精細度を上げ て表示することのできるデュアルビューディスプレイを実現することにある。  [0013] The present invention has been made in view of the above problems, and an object thereof is to realize a dual view display capable of displaying with higher definition.
課題を解決するための手段  Means for solving the problem
[0014] 本発明に係るデュアルビューディスプレイは、上記課題を解決するために、 3つの 原色の各原色に対応する絵素が行列状に配置され、第 1方向と第 2方向とにそれぞ れ異なる画像を表示するデュアルビューディスプレイにおいて、上記絵素は、列毎に 上記第 1方向用と上記第 2方向用とが交互に配列され、かつ、任意の列において隣 接する 2つの絵素と、当該隣接する 2つの絵素の行方向の 2つ隣りの絵素の何れか 一つと力 それぞれ異なる 3色となるように配列されることを特徴としている。  In the dual view display according to the present invention, in order to solve the above-described problem, picture elements corresponding to the three primary colors are arranged in a matrix, and the first direction and the second direction are respectively provided. In a dual-view display that displays different images, the picture elements are alternately arranged in the first direction and the second direction for each column, and two adjacent pixel elements in any column, and The two adjacent picture elements are arranged so as to have three colors different in power from any one of the two neighboring picture elements in the row direction.
[0015] 上記構成によると、行列状に配置される 3つの原色の各原色に対応する絵素は、列 毎に第 1方向用と第 2方向用とが交互に配列され、かつ、任意の列において隣接す る 2つの絵素と、当該隣接する 2つの絵素の行方向の 2つ隣りの絵素の何れか一つと 力 それぞれ異なる 3色となるように配列される。ここで、原色とは、任意の割合で混 ぜることにより、全ての色を表せる 3つの異なった色のことである。  [0015] According to the above configuration, the picture elements corresponding to the primary colors of the three primary colors arranged in a matrix are alternately arranged for the first direction and for the second direction for each column. Two adjacent picture elements in the column and one of the two adjacent picture elements in the row direction of the two adjacent picture elements are arranged so as to have three different colors. Here, the primary colors are three different colors that can be expressed by mixing them in any proportion.
[0016] よって、任意の 2行 3列の絵素領域内と、この絵素領域に対して行方向に 1絵素分 ずれた 2行 3列の絵素領域内とにそれぞれ第 1方向用の異なる 3つの原色(3原色) の絵素と、第 2方向用の異なる 3つの原色(3原色)の絵素とを配置することができる。 つまり、行方向の絵素ピッチを従来の単一表示ディスプレイと同じに保ったまま、従 来の単一表示ディスプレイの異なる 3つの原色の絵素からなる区画とほぼ同じ区画の 中に、第 1方向用の異なる 3つの原色の絵素と第 2方向用の異なる 3つの原色の絵素 とを酉己置することがでさる。  [0016] Therefore, the first direction is used for an arbitrary two-row and three-column pixel area and a two-row and three-column pixel area that is shifted by one pixel in the row direction with respect to this pixel area. It is possible to arrange picture elements of three different primary colors (three primary colors) and three different primary colors (three primary colors) for the second direction. In other words, while maintaining the same pixel pitch in the row direction as that of the conventional single display, the first one is in the same section as the section consisting of the three primary color picture elements of the conventional single display. It is possible to place three different primary color picture elements for the direction and three different primary color picture elements for the second direction.
[0017] このように、行方向の絵素ピッチが短くならないので、絵素の形状が、列方向と行方 向の比において列方向に長い形状とはならない。よって、輝度を確保し、 CF側のガ ラス基板の膜厚を減少させることなぐデュアルビュー表示の視角特性を保ったまま、 高詳細化してデュアルビュー表示を行うことができる。 As described above, since the pixel pitch in the row direction is not shortened, the shape of the pixel does not become a shape that is long in the column direction in the ratio of the column direction to the row direction. Therefore, the brightness is secured and the CF side The dual view display can be performed with high detail while maintaining the viewing angle characteristics of the dual view display without reducing the thickness of the glass substrate.
[0018] また、絵素は、列毎に第 1方向用と第 2方向用とが交互に配列されているので、この 列に沿った遮光部を設けた視差バリア等の光学分離素子で、上記第 1方向用の画 像と上記第 2方向用の画像とを分離することができる。列に沿った遮光部を設けた光 学分離素子を用いるため、列方向の光漏れは気にしなくてもよい。  [0018] Also, since the picture elements are alternately arranged for the first direction and for the second direction for each column, an optical separation element such as a parallax barrier provided with a light shielding portion along this column, The image for the first direction and the image for the second direction can be separated. Since an optical separation element provided with a light blocking portion along the column is used, light leakage in the column direction does not have to be taken care of.
[0019] 例えば、第 1方向用の絵素と第 2方向用の絵素とが行において交互に、かつ、行毎 に一つずらして配列されており、遮光部を格子状に設けると、列方向、行方向の両方 に対して、光漏れを考慮する必要がある。この場合、遮光部の配置位置の誤差を考 慮して、広めに遮光部を設ける必要がある。よって、このような遮光部を設けたデイス プレイでは、開口率、および、コントラスト比等の低下が起きてしまうことになる。  [0019] For example, when the first direction picture element and the second direction picture element are arranged alternately in the row and shifted by one for each row, and the light-shielding portions are provided in a lattice shape, It is necessary to consider light leakage in both the column and row directions. In this case, it is necessary to provide a light shielding portion wider in consideration of an error in the arrangement position of the light shielding portion. Therefore, in a display provided with such a light-shielding portion, the aperture ratio, contrast ratio, and the like are reduced.
[0020] しかし、上記構成によると、絵素は列毎に第 1方向用と第 2方向用とが交互に配列さ れているので、絵素の列方向に連続した遮光部にて遮光することができる。そして、 その遮光部の配置は、絵素の列方向に関しては、配置に多少ずれがあっても、列方 向からの光を効果的に遮光することができ、第 1方向に表示される画像と第 2方向に 表示される画像とを、互いに影響することなぐ高性能に分離することができる。  [0020] However, according to the above configuration, since the pixels are alternately arranged for the first direction and for the second direction for each column, the pixels are shielded by the light-shielding portion continuous in the column direction of the pixels. be able to. The arrangement of the light-shielding portions can effectively block the light from the row direction even if there is a slight deviation in the row direction of the picture elements, and the image displayed in the first direction. And the image displayed in the second direction can be separated with high performance without affecting each other.
[0021] また、本発明に係るデュアルビューディスプレイは、上記構成に加え、上記異なる 3 色は、赤,青,緑の 3原色である。  [0021] Further, in the dual view display according to the present invention, in addition to the above configuration, the three different colors are three primary colors of red, blue and green.
[0022] 上記構成によると、任意の列において隣接する 2つの絵素と、当該隣り合う 2つの絵 素の行方向の 2つ隣りの 2つの絵素のどちらか一方とにおいて、それぞれ 3原色の 1 つを配置させることで、第 1方向に表示される画像と第 2方向に表示される画像とが、 どのような色からなる画像であっても、高再現性にて表示することができる、デュアル ビューディスプレイを提供することができる。  [0022] According to the above configuration, each of the three primary colors in each of two adjacent picture elements in an arbitrary column and two adjacent two picture elements in the row direction of the two adjacent pixels. By arranging one, it is possible to display images with high reproducibility regardless of the color of the image displayed in the first direction and the image displayed in the second direction. A dual view display can be provided.
[0023] また、本発明に係るデュアルビューディスプレイは、上記構成に加え、上記絵素の 任意の列にお 、て、異なる 3色が含まれるように配置されてもょ 、。  [0023] Further, in addition to the above configuration, the dual view display according to the present invention may be arranged so that three different colors are included in any column of the picture element.
[0024] 上記構成によると、どの列にも異なる 3色の絵素が含まれることになる。よって、絵素 の列方向に信号線が配置される場合に、単色画像を表示させる場合にも、絵素の列 に対応する複数の信号線のそれぞれの実効電圧の差を少なくすることができる。よつ て、列方向のスジムラの発生を防ぐことができる。 [0024] According to the above configuration, three columns of different color elements are included in every column. Therefore, when signal lines are arranged in the pixel column direction, even when displaying a monochromatic image, it is possible to reduce the difference in effective voltage of each of the signal lines corresponding to the pixel column. . Yotsu Thus, the occurrence of uneven stripes in the column direction can be prevented.
[0025] また、本発明に係るデュアルビューディスプレイは、上記構成に加え、上記絵素の 任意の行にぉ 、て、同じ色の絵素が 2つずつ繰り返されてもよ 、。  [0025] Further, in addition to the above configuration, the dual view display according to the present invention may repeat two identical picture elements in any row of the picture elements.
[0026] 上記構成によると、上記絵素の任意の行において、同じ色の絵素が 2つずつ繰り返 されるので、デュアルビューディスプレイの製造におけるカラーフィルターを製造する 際、 2つの絵素に対する色パターンを、 2つまとめて、あるいは、 2倍の大きさの 1つの パターンとして次々配置させていくことができる。よって、カラーフィルターを効率よく 製造することができる。  [0026] According to the above configuration, two pixels of the same color are repeated two by two in any row of the pixel, so when manufacturing a color filter in the manufacture of a dual view display, Two color patterns can be arranged one after the other or as one pattern that is twice as large. Therefore, the color filter can be manufactured efficiently.
[0027] また、本発明に係るデュアルビューディスプレイは、上記構成に加え、上記絵素の 列方向に連続した遮光部を備えた光学分離素子を備えて 、る。  In addition to the above configuration, a dual view display according to the present invention includes an optical separation element including a light shielding portion that is continuous in the column direction of the picture elements.
[0028] 上記構成によると、光学分離素子において遮光層が絵素の列方向に連続して形成 されている。そのため、絵素に対する光学分離素子の配置において、絵素の列方向 に関しては、光学分離素子の配置に多少ずれがあっても、列方向からの光を効果的 に遮光することができ、第 1方向に表示される画像と第 2方向に表示される画像とを、 互いに影響することなぐ高性能に分離することができる。  [0028] According to the above configuration, the light shielding layer is formed continuously in the column direction of the picture element in the optical separation element. Therefore, in the arrangement of the optical separation element with respect to the picture element, the light from the column direction can be effectively shielded even if the arrangement of the optical separation element is slightly shifted with respect to the column direction of the picture element. The image displayed in the direction and the image displayed in the second direction can be separated with high performance without affecting each other.
[0029] このように、光学分離素子の絵素の列方向に対する配置つ!/、ては、誤差の許容範 囲を広くとることができ、配置を容易にすることができる。そのため、光学分離素子の 配置において高い精度は要求されなくなり、また、配置に要する時間も短縮すること ができる。よって、デュアルビューディスプレイの製造において、コストと時間の削減を 行って、光漏れのない、信頼性の高い高品質のデュアルビューディスプレイを提供す ることがでさる。  [0029] In this manner, the arrangement of the optical separation elements in the column direction of the picture elements can be widened and the arrangement can be facilitated. For this reason, high accuracy is not required in the arrangement of the optical separation elements, and the time required for the arrangement can be shortened. Therefore, it is possible to reduce the cost and time in manufacturing the dual view display and provide a reliable and high quality dual view display without light leakage.
発明の効果  The invention's effect
[0030] 本発明に係るデュアルビューディスプレイは、以上のように、上記絵素は、列毎に上 記第 1方向用と上記第 2方向用とが交互に配列され、かつ、任意の列において隣接 する 2つの絵素と、当該隣接する 2つの絵素の行方向の 2つ隣りの絵素の何れか一 つと力 それぞれ異なる 3色となるように配列される。  [0030] As described above, in the dual view display according to the present invention, the picture element is alternately arranged for the first direction and for the second direction for each column, and in any column. The two adjacent picture elements and the two adjacent picture elements in the row direction of the two adjacent picture elements are arranged so as to have three different colors.
[0031] 上記構成によると、行列状に配置される 3つの原色の各原色に対応する絵素は、列 毎に第 1方向用と第 2方向用とが交互に配列され、かつ、任意の列において隣接す る 2つの絵素と、当該隣接する 2つの絵素の行方向の 2つ隣りの絵素の何れか一つと 力 それぞれ異なる 3色となるように配列される。ここで、原色とは、任意の割合で混 ぜることにより、全ての色を表せる 3つの異なった色のことである。 [0031] According to the above configuration, the pixels corresponding to the primary colors of the three primary colors arranged in a matrix are alternately arranged for the first direction and for the second direction for each column, and any Adjacent in a row Are arranged in three colors that are different from each other and one of the two neighboring pixels in the row direction of the two adjacent pixels. Here, the primary colors are three different colors that can be expressed by mixing them in any proportion.
[0032] よって、任意の 2行 3列の絵素領域内と、この絵素領域に対して行方向に 1絵素分 ずれた 2行 3列の絵素領域内とにそれぞれ第 1方向用の異なる 3つの原色(3原色) の絵素と第 2方向用の異なる 3つの原色(3原色)の絵素とを配置することができる。 つまり、行方向の絵素ピッチを従来の単一表示ディスプレイと同じに保ったまま、従 来の単一表示ディスプレイの異なる 3色の絵素力もなる区画とほぼ同じ区画の中に、 第 1方向用の異なる 3色の絵素と第 2方向用の異なる 3色の絵素とを配置することが できる。 [0032] Therefore, for the first direction, an arbitrary 2 × 3 pixel area and a 2 × 3 pixel area shifted by 1 picture element in the row direction from this pixel area, respectively. 3 primary colors (3 primary colors) and 3 different primary colors (3 primary colors) for the second direction can be arranged. In other words, while maintaining the same pixel pitch in the row direction as that of the conventional single display, the first direction is in the same section as the section where the conventional three-display pixel power is different. Different three-color picture elements for the second direction and different three-color picture elements for the second direction can be arranged.
[0033] このように、行方向の絵素ピッチが短くならないので、絵素の形状が、列方向と行方 向の比において列方向に長い形状とはならない。よって、輝度を確保し、 CF側のガ ラス基板の膜厚を減少させることなぐデュアルビュー表示の視角特性を保ったまま、 高詳細化してデュアルビュー表示を行うことができる。  As described above, since the pixel pitch in the row direction is not shortened, the shape of the pixel does not become a shape that is long in the column direction in the ratio of the column direction to the row direction. Therefore, high-detail dual view display can be performed while maintaining the viewing angle characteristics of dual view display without securing the luminance and reducing the film thickness of the glass substrate on the CF side.
[0034] また、絵素は、列毎に第 1方向用と第 2方向用とが交互に配列されているので、この 列に沿った遮光部を設けた視差バリア等の光学分離素子で、上記第 1方向用の画 像と上記第 2方向用の画像とを分離することができる。列に沿った遮光部を設けた光 学分離素子を用いるため、列方向の光漏れは気にしなくてもよい。  [0034] Further, since the picture elements are alternately arranged for the first direction and for the second direction for each column, an optical separation element such as a parallax barrier provided with a light shielding portion along this column, The image for the first direction and the image for the second direction can be separated. Since an optical separation element provided with a light blocking portion along the column is used, light leakage in the column direction does not have to be taken care of.
[0035] 例えば、第 1方向用の絵素と第 2方向用の絵素とが行において交互に、かつ、行毎 に一つずらして配列されており、遮光部を格子状に設けると、列方向、行方向の両方 に対して、光漏れを考慮する必要がある。この場合、遮光部の配置位置の誤差を考 慮して、広めに遮光部を設ける必要がある。よって、このような遮光部を設けたデイス プレイでは、開口率、および、コントラスト比等の低下が起きてしまうことになる。  [0035] For example, when the first-direction picture elements and the second-direction picture elements are arranged alternately in the rows and shifted by one for each row, and the light-shielding portions are provided in a grid pattern, It is necessary to consider light leakage in both the column and row directions. In this case, it is necessary to provide a light shielding portion wider in consideration of an error in the arrangement position of the light shielding portion. Therefore, in a display provided with such a light-shielding portion, the aperture ratio, contrast ratio, and the like are reduced.
[0036] しかし、上記構成によると、絵素は列毎に第 1方向用と第 2方向用とが交互に配列さ れているので、絵素の列方向に連続した遮光部にて遮光することができる。そして、 その遮光部の配置は、絵素の列方向に関しては、配置に多少ずれがあっても、列方 向からの光を効果的に遮光することができ、第 1方向に表示される画像と第 2方向に 表示される画像とを、互いに影響することなぐ高性能に分離することができる。 図面の簡単な説明 [0036] However, according to the above configuration, since the pixels are alternately arranged for the first direction and for the second direction for each column, the pixels are shielded by the light shielding portion continuous in the column direction of the pixels. be able to. The arrangement of the light-shielding portions can effectively block the light from the row direction even if there is a slight deviation in the row direction of the picture elements, and the image displayed in the first direction. And the image displayed in the second direction can be separated with high performance without affecting each other. Brief Description of Drawings

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0039] 本発明の一実施形態について図 1〜図 6、図 9に基づいて説明すると以下の通りで ある。 One embodiment of the present invention will be described below with reference to FIGS. 1 to 6 and FIG.
[0040] なお、本発明に係るデュアルビューディスプレイは、デュアルビュー表示機能を備 えていればよぐ例えば液晶ディスプレイ、無機 ELディスプレイ、有機 ELディスプレ ィ、プラズマディスプレイ、 CRTディスプレイ等の種々の表示装置を含む広い概念で あり、表示機構により限定されるものではない。  [0040] Note that the dual view display according to the present invention may have various display devices such as a liquid crystal display, an inorganic EL display, an organic EL display, a plasma display, and a CRT display as long as it has a dual view display function. It is a broad concept that includes and is not limited by the display mechanism.
[0041] また、本実施形態では、デュアルビューディスプレイは、右観察方向と左観察方向 とに異なる画像を表示するものとし、列方向を縦方向、行方向を横方向として説明す る力 例えば、列方向が横方向と行方向が縦方向になっており、上下の 2方向に向け て異なる表示を行うものであってもよ 、。  [0041] Further, in the present embodiment, the dual view display displays different images in the right observation direction and the left observation direction, and the force for explaining the column direction as the vertical direction and the row direction as the horizontal direction. The column direction may be the horizontal direction and the row direction may be the vertical direction, and the display may be different in the upper and lower directions.
[0042] 本実施形態のデュアルビューディスプレイは、従来と同様、図 9に示すように、ディ スプレイパネル 10と視差バリア基板 20とを備えている。  The dual view display according to the present embodiment includes a display panel 10 and a parallax barrier substrate 20 as shown in FIG.
[0043] ディスプレイパネル 10において、絵素の配列は、図 1 (a)〖こ示すように、行および列 に配置され、列毎に上記右観察方向 (第 1方向)用と左観察方向 (第 2方向)用とが交 互に配列され、かつ、任意の列において隣接する 2つの絵素と、当該隣接する 2つの 絵素の行方向の 2つ隣りの絵素の何れか一つと力 それぞれ異なる 3つの原色 (R, B, G)となるように配列されている。ここで、絵素とは、各色 (R (赤), B (青), G (緑) ) を表示させる最小単位を指すものとする。なお、原色とは、任意の割合で混ぜること により、全ての色を表せる 3つの異なった色のことであり、本実施形態では、異なる 3 つの原色(3原色)を R, B, Gとする力 これに限定されることはない。 [0043] In the display panel 10, the arrangement of picture elements is arranged in rows and columns as shown in Fig. 1 (a), and for each column, the right observation direction (first direction) and the left observation direction ( For the second direction), and two adjacent picture elements in any row and the two adjacent It is arranged so that it has three primary colors (R, B, G) that are different from any one of the two neighboring pixel elements in the row direction. Here, the picture element refers to the minimum unit for displaying each color (R (red), B (blue), G (green)). The primary colors are three different colors that can be expressed by mixing them at an arbitrary ratio. In this embodiment, the three different primary colors (three primary colors) are R, B, and G. Power It is not limited to this.
[0044] 図 1 (a)では、各絵素は、 1行目を例にとると、図面向力つて左から、右観察方向画 像表示用の Rの絵素 (Rr)、左観察方向画像表示用の Gの絵素 (G1)、右観察方向画 像表示用の Bの絵素(Br)、左観察方向画像表示用の Rの絵素 (R1)、右観察方向画 像表示用の Gの絵素(Gr)、左観察方向画像表示用の Bの絵素(B1)のように配列さ れている。なお、図 1 (b)は、絵素が図 1 (a)の構成となっているデュアルビューデイス プレイで用いられる視差バリア基板の構成を示すものである。  [0044] In Fig. 1 (a), for each picture element, taking the first line as an example, the right picture direction from the left in the drawing direction, right picture direction R picture element (Rr), left picture direction G picture element (G1) for image display, B picture element (Br) for right observation direction image display, R picture element (R1) for left observation direction image display, right observation direction image display The G picture element (Gr) and the B picture element (B1) for displaying the left viewing direction image are arranged. FIG. 1 (b) shows the configuration of the parallax barrier substrate used in the dual view display in which the picture elements have the configuration shown in FIG. 1 (a).

も力まわない。これは、以下で説明する図 2, 3, 6でも同様である。  Does not help. The same applies to FIGS. 2, 3 and 6 described below.
[0046] 本実施形態のデュアルビューディスプレイは、ディスプレイパネル 10と視差バリア基 板 20とにより、ディスプレイパネル 10を右側から観察するの観察者の観察方向であ る右観察方向と、左側からの観察する観察者の観察向である左観察方向とにそれぞ れ異なる画像を表示することができる。 [0046] The dual view display of the present embodiment uses the display panel 10 and the parallax barrier substrate 20 to observe the right observation direction, which is the observation direction of the observer who observes the display panel 10 from the right side, and the observation from the left side. Different images can be displayed in the left viewing direction, which is the viewing direction of the observer.
[0047] ディスプレイパネル 10は、右観察方向に右観察表示用画像を、左観察方向に左観 察表示用画像を表示する。ディスプレイパネル 10は、例えば液晶ディスプレイパネル[0047] The display panel 10 displays a right observation display image in the right observation direction and a left observation display image in the left observation direction. The display panel 10 is, for example, a liquid crystal display panel
、プラズマディスプレイパネル、有機 ELディスプレイパネル、無機 ELディスプレイパ ネル等であってもよいし、 CRTであってもよい。 It may be a plasma display panel, an organic EL display panel, an inorganic EL display panel, etc., or a CRT.
[0048] 視差バリア基板 (光学分離素子) 20は、図 1 (b)に示すように、絵素の列方向に連 続した遮光部 30を備えている。視差バリア基板 20は、絵素の列(図 1では縦)方向に 配列された複数の遮光部 30によって隔たれた透過部 40を複数有するスクリーンであ る。 [0048] As shown in Fig. 1 (b), the parallax barrier substrate (optical separation element) 20 is connected in the column direction of the picture elements. A continuous shading unit 30 is provided. The parallax barrier substrate 20 is a screen having a plurality of transmission parts 40 separated by a plurality of light shielding parts 30 arranged in the direction of picture elements (vertical in FIG. 1).
[0049] 図 9に示すように、ディスプレイパネル 10の絵素 Rr, Gr, Brを透過した光が複数の 透過部 40を介して右視角からの観察者に到達し、絵素 Rl, Gl, B1を透過した光が複 数の透過部 40を介して左視角力もの観察者に到達する。言い換えれば、ディスプレ ィパネル 10に表示されるそれぞれ異なる画像は、視差バリア基板 20の複数の遮光 部により、空間上の規定された領域 (右観察方向、左観察方向)からしか見えないよう になっている。  [0049] As shown in Fig. 9, the light transmitted through the picture elements Rr, Gr, Br of the display panel 10 reaches the observer from the right viewing angle via the plurality of transmission parts 40, and the picture elements Rl, Gl, The light that has passed through B1 reaches the observer with the left visual angle power through multiple transmission parts 40. In other words, each different image displayed on the display panel 10 can be seen only from a prescribed area (right observation direction, left observation direction) in the space by the plurality of light shielding portions of the parallax barrier substrate 20. Yes.
[0050] 上記のように、視差バリア基板 20において遮光部 30が絵素の列方向に連続して形 成されている。そのため、絵素に対する視差バリア基板 20の配置において、絵素の 列方向に関しては、視差バリア基板 20の配置に多少ずれがあっても、列方向からの 光を効果的に遮光することができ、右観察方向に表示される画像と左観察方向に表 示される画像とを、互いに影響することなぐ高性能に分離して表示することができる  [0050] As described above, in the parallax barrier substrate 20, the light shielding portions 30 are formed continuously in the column direction of the picture elements. Therefore, in the arrangement of the parallax barrier substrate 20 with respect to the picture elements, the light from the column direction can be effectively blocked even if the arrangement of the parallax barrier board 20 is slightly shifted with respect to the column direction of the picture elements. The image displayed in the right viewing direction and the image displayed in the left viewing direction can be separated and displayed with high performance without affecting each other.
[0051] このように、視差バリア基板 20の絵素の列方向に対する配置ついては、誤差の許 容範囲を広くとることができ、配置を容易にすることができる。そのため、視差バリア基 板 20の配置において高い精度は要求されなくなり、また、配置に要する時間も短縮 することができる。よって、デュアルビューディスプレイの製造において、コストと時間 の削減を行って、光漏れのない、信頼性の高い高品質のデュアルビューディスプレイ を提供することができる。 [0051] As described above, with respect to the arrangement of the parallax barrier substrate 20 in the column direction of the picture elements, an allowable range of errors can be widened, and the arrangement can be facilitated. Therefore, high accuracy is not required in the arrangement of the parallax barrier substrate 20, and the time required for the arrangement can be shortened. Therefore, it is possible to reduce the cost and time in manufacturing the dual view display, and to provide a reliable and high quality dual view display without light leakage.
[0052] 上記のような絵素の配列により、任意の 2行 3列の絵素領域内と、この絵素領域に 対して行方向に 1絵素分ずれた 2行 3列の絵素領域内とにそれぞれ第 1方向用の異 なる 3色の絵素と第 2方向用の異なる 3色の絵素とを配置することができる。よって、図 10に示した単一表示ディスプレイの R, G, Bの 3絵素からなる画素の区画(図 10の 点線で囲まれた部分)とほぼ同じ区画 (ここでいう「ほぼ同じ区画」とは、例えば、 R r  [0052] Due to the arrangement of the picture elements as described above, a picture element area of 2 rows and 3 columns that is shifted by one picture element in the row direction with respect to this picture element area in an arbitrary 2 rows and 3 columns picture element area. Different three-color picture elements for the first direction and different three-color picture elements for the second direction can be arranged respectively. Therefore, it is almost the same as the pixel block consisting of the three picture elements R, G, and B of the single display shown in Fig. 10 (the part surrounded by the dotted line in Fig. 10). For example, R r
11 11
、G 1、B r、R 1、G r、B 1の配置された L字型の区画を指す。この区画は、図 10, G 1, B r, R 1, G r, B 1 refers to the L-shaped section. This section is shown in Figure 10.
11 11 11 11 11 11 11 11 11 11
の点線で囲まれた矩形の区画とは完全には一致はしないが、面積は同一であり、形 状も比較的近い。)の中に、 Rr, Gr, Br, Rl, Gl, Blの 6絵素を配置することができる 。つまり、行方向の絵素ピッチを従来の単一表示ディスプレイと同じに保ったまま、従 来の単一表示ディスプレイの異なる 3色の絵素力もなる区画とほぼ同じ区画の中に、 第 1方向用の異なる 3色の絵素と第 2方向用の異なる 3色の絵素とを配置することが できる。ここで、絵素とは、色を表示させる最小単位を指すものとする。 It does not completely match the rectangular section surrounded by the dotted line, but the area is the same and the shape is The shape is also relatively close. ), 6 picture elements of Rr, Gr, Br, Rl, Gl, Bl can be arranged. In other words, while maintaining the same pixel pitch in the row direction as that of the conventional single display, the first direction is in the same section as the section where the conventional three-display pixel power is different. Different three-color picture elements for the second direction and different three-color picture elements for the second direction can be arranged. Here, the picture element indicates a minimum unit for displaying a color.
[0053] このように、行方向の絵素ピッチが短くならないので、絵素の形状が、列方向と行方 向の比において列方向に長い形状とはならない。よって、輝度を確保し、 CF側のガ ラス基板の膜厚を減少させることなぐデュアルビュー表示の視角特性を保ったまま、 高詳細化してデュアルビュー表示を行うことができる。  [0053] Thus, since the pixel pitch in the row direction does not become short, the shape of the pixel does not become a shape that is long in the column direction in the ratio of the column direction to the row direction. Therefore, high-detail dual view display can be performed while maintaining the viewing angle characteristics of dual view display without securing the luminance and reducing the film thickness of the glass substrate on the CF side.
[0054] また、絵素は、列毎に右観察方向用と左観察方向用とが交互に配列されているの で、この列に沿った遮光部を設けた視差バリア等の光学分離素子で、右観察方向用 の画像と左観察方向用の画像とを分離することができる。列に沿った遮光部を設けた 光学分離素子を用いるため、列方向の光漏れは気にしなくてもよい。  [0054] Also, since the picture elements are alternately arranged for the right observation direction and the left observation direction for each column, an optical separation element such as a parallax barrier provided with a light shielding portion along this column is used. The image for the right observation direction and the image for the left observation direction can be separated. Since an optical separation element provided with a light shielding portion along the row is used, light leakage in the row direction does not have to be considered.
[0055] 例えば、右観察方向用の絵素と左観察方向用の絵素とが行において交互に、かつ 、行毎に一つずらして配列されており、遮光部を格子状に設けると、列方向、行方向 の両方に対して、光漏れを考慮する必要がある。この場合、遮光部の配置位置の誤 差を考慮して、広めに遮光部を設ける必要がある。よって、このような遮光部を設けた ディスプレイでは、開口率、および、コントラスト比等の低下が起きてしまうことになる。  [0055] For example, when the picture element for the right observation direction and the picture element for the left observation direction are arranged alternately in the row and shifted by one for each row, and the light-shielding portions are provided in a lattice shape, It is necessary to consider light leakage in both the column and row directions. In this case, it is necessary to provide a light shielding part wider in consideration of an error in the arrangement position of the light shielding part. Therefore, in a display provided with such a light shielding portion, the aperture ratio, the contrast ratio, and the like are lowered.
[0056] しかし、本実施の形態デュアルビューディスプレイによると、絵素は列毎に右観察方 向用と左観察用とが交互に配列されているので、絵素の列方向に連続した遮光部に て遮光することができる。そして、その遮光部の配置は、絵素の列方向に関しては、 配置に多少ずれがあっても、列方向力もの光を効果的に遮光することができ、右観 察方向に表示される画像と左観察方向に表示される画像とを、互いに影響することな ぐ高性能に分離することができる。  However, according to the dual view display of the present embodiment, since the picture elements are alternately arranged for the right observation direction and for the left observation for each column, the light-shielding portion continuous in the column direction of the picture elements. Therefore, it can be shielded from light. The arrangement of the light-shielding portion can effectively block light in the column direction even if the arrangement of the pixels is slightly shifted, and the image displayed in the right viewing direction. And the image displayed in the left viewing direction can be separated with high performance without affecting each other.
[0057] なお、映像信号源から、画像(映像)として信号がデュアルビューディスプレイに入 力される。映像信号源は、画像を示す信号を出力できるものであれば、どのようなも のであっても力まわなぐ例えば、ビデオやチューナ一等が挙げられる。よって、本実 施形態のデュアルビューディスプレイは、映像信号源から、右観察方向(第 1方向)に 応じた画像を右観察方向画像表示用の絵素に、左観察方向(第 2方向)に応じた画 像を左観察方向表示用の絵素に供給するコントローラを備えている。このコントローラ の構成は、従来公知のものが好適に用いることができる。また、他の記載される以外 の構成は、従来のデュアルビューディスプレイを同様であるため、説明は省略する。 Note that a signal is input as an image (video) from the video signal source to the dual view display. As long as the video signal source can output a signal indicating an image, any video signal source can be used, such as a video or a tuner. Therefore, the dual view display of this embodiment is in the right observation direction (first direction) from the video signal source. A controller is provided that supplies the corresponding image to the picture element for displaying the right observation direction and the image corresponding to the left observation direction (second direction) to the picture element for displaying the left observation direction. A conventionally known controller configuration can be suitably used. Other configurations other than those described are the same as those of the conventional dual view display, and thus the description thereof is omitted.
[0058] ここで、従来の単一表示ディスプレイでは、図 12に示すように、信号線と走査線、そ のクロス部にアクティブ素子、また、アクティブ素子を介して信号線に接続された絵素 電極が配置される。一般に信号線と絵素電極の間には寄生容量 Csdがあるため、信 号線の電圧がこの Csdを介して絵素電極電位に影響を与える。絵素電極 Rは、 Csd を介して信号線 1および信号線 2の影響を受ける。このうち、信号線 2は G2に表示す る画像の信号を表示しているため、信号線 2の信号電圧は絵素電極 Rの絵素電位と は無関係な信号が入力される。信号線 1を介して絵素電極 Rに同じ電位を与えた場 合でも、信号線 2の信号電圧が異なれば、 Csdを介した信号線 2の Rへの影響によ つて、 Rの絵素電極電位異なる。このため Rの輝度は信号線 2の信号電圧によって も変化する。ただし、通常の単一表示ディスプレイの場合、信号線 2の信号電圧が大 きく異なるのは、表示画像の境界 (例えば白画面に黒ウィンドウを表示した場合の白 と黒表示の境界)のみであり、この場合には画像境界部分の絵素電位が影響を受け て絵素の輝度が若干変わったとしても、画像の境界であるために視認されることはほ とんど無ぐ問題は発生しない。  Here, in the conventional single display, as shown in FIG. 12, the signal line and the scanning line, the active element at the cross portion thereof, and the picture element connected to the signal line through the active element are provided. An electrode is placed. In general, since there is a parasitic capacitance Csd between the signal line and the pixel electrode, the voltage of the signal line affects the pixel electrode potential via this Csd. The pixel electrode R is affected by the signal lines 1 and 2 via Csd. Among these, since the signal line 2 displays an image signal to be displayed on G2, a signal unrelated to the pixel potential of the pixel electrode R is input to the signal voltage of the signal line 2. Even if the same potential is applied to the pixel electrode R via the signal line 1, if the signal voltage of the signal line 2 is different, the influence on the R of the signal line 2 via Csd will affect the R pixel. The electrode potential is different. For this reason, the luminance of R also changes depending on the signal voltage of signal line 2. However, in the case of a normal single display, the signal voltage of signal line 2 is greatly different only in the boundary of the display image (for example, the boundary between white and black display when a black window is displayed on a white screen). In this case, even if the picture element potential at the border of the image is affected and the luminance of the picture element changes slightly, there is almost no problem that it is visually recognized because it is the border of the picture. .
[0059] 一方、本発明のデュアルビューディスプレイは、従来のデュアルビューディスプレイ 同様、図 13に示すように、寄生容量 Csdにより例えば Rrは信号線 1および信号線 2 の影響を受ける。このうち信号線 2には Rrとは観察方向の異なる左観察方向の表示 信号が入力されている。デュアルビュー表示の場合、右観察方向画面と左観察方向 画面とは全く独立な画像が表示される。このため、表示画像の境界部でなくとも信号 線 1と信号線 2との信号電圧が大きく異なる場合があり、この場合、信号線 2の影響が 視認される場合がある。例えば、右観察方向画面全面に白画像を表示し、左観察方 向画面に白い背景に黒いウィンドウを表示した場合などである。つまり、 Csdを介し  On the other hand, in the dual view display of the present invention, as in the conventional dual view display, for example, Rr is affected by the signal line 1 and the signal line 2 due to the parasitic capacitance Csd, as shown in FIG. Of these, the display signal in the left observation direction, which is different from the observation direction from Rr, is input to signal line 2. In the case of dual view display, an image completely independent of the right observation direction screen and the left observation direction screen is displayed. For this reason, the signal voltage of the signal line 1 and the signal line 2 may be greatly different from each other even at the boundary portion of the display image. In this case, the influence of the signal line 2 may be visually recognized. For example, a white image is displayed on the entire right observation direction screen, and a black window is displayed on the white observation direction screen on a white background. That is, via Csd
2 て右観察方向画面に左観察方向画面の画像が映り込む現象が発生する。これを防 止するために、異なる観察方向の信号を入力している信号線との Csd (Rrに対して は Csd )は、表示に影響しない程度に小さくなるように、設計してある。 2 The image of the left observation direction screen is reflected on the right observation direction screen. In order to prevent this, Csd (with respect to Rr) Csd) is designed to be small enough not to affect the display.

[0060] 以上のように、本実施形態のデュアルビューディスプレイにお 、て、絵素は、行およ び列に配置され、列毎に上記右観察方向 (第 1方向)用と左観察方向 (第 2方向)用と が交互に配列され、かつ、任意の列において隣接する 2つの絵素と、当該隣接する 2 つの絵素の行方向の 2つ隣りの 2つの絵素の何れか一つと力 それぞれ異なる 3色( R, B、 G)となるように配列されていればよい。つまり、図 1に示す絵素の配列の代わ りに、次に説明する図 2, 3, 4のような配列になっていてもよい。  [0060] As described above, in the dual view display of the present embodiment, the picture elements are arranged in rows and columns, and for the right observation direction (first direction) and the left observation direction for each column. (Second direction) are alternately arranged, and one of two neighboring picture elements in any column and two neighboring two picture elements in the row direction of the two neighboring picture elements. As long as they are arranged in three different colors (R, B, G). In other words, instead of the pixel arrangement shown in FIG. 1, the arrangement shown in FIGS.
[0061] 図 2に示す絵素の配列は、図 1に比べ、列方向の配列は図 1と同様である。行方向 の配列において、同じ色の絵素が 2つずつ繰り返される。よって、デュアルビューディ スプレイの製造におけるカラーフィルターを製造する際、 2つの絵素に対する色バタ ーンを、 2つまとめて、あるいは、 2倍の大きさの 1つのパターンとして次々配置させて いくことができる。よって、カラーフィルターを効率よく製造することができる。  The arrangement of picture elements shown in FIG. 2 is the same as that of FIG. Two pixels of the same color are repeated in the row-wise array. Therefore, when manufacturing color filters in the manufacture of dual-view displays, color patterns for two picture elements should be arranged one after the other or as a pattern that is twice as large. Can do. Therefore, a color filter can be manufactured efficiently.
[0062] また、図 3に示す絵素の配列は、列方向の配列において R, B, Gが繰り返されてい る。この場合、次のような効果がある。つまり、図 1のように絵素を配置した場合、図 4 に示すように、信号線が絵素の列方向に沿っている場合、ある信号線 1には、 Rおよ び Bのみの絵素電極が接続され、ある信号線 3には、 Bおよび Gのみの絵素電極が 接続されることになる。この配列のディスプレイで、例えば緑といった単色画面を表示 すると、信号線 1と信号線 3とに入力される信号電圧の実効電圧は異なる。この信号 線の実効電圧の差は信号線と絵素電極の間の寄生容量 Csdを介して絵素電極電位 にも影響を与え、信号線 1に接続されて ヽる絵素電極 Brの電位と信号線 3に接続さ れている絵素電極 Brの電位は同じではなくなる。そのため、この電位に差ができるこ とにより、表示に、縦スジ状 (絵素の列方向)のムラが現れ、表示品位が低下する場合 がある。しかし、図 3のように絵素を配置した場合、信号線と絵素の接続は図 5に示す ようになり、複数の信号線において (信号線 1と信号線 3とも) R, G, Bの絵素が均等 に接続される。そのため、単色画面を表示した場合にも、複数の信号線に入力される 実効電圧は等しくなり、縦スジ状のムラは発生することは無くなる。  [0062] In addition, in the pixel arrangement shown in Fig. 3, R, B, and G are repeated in the arrangement in the column direction. In this case, there are the following effects. In other words, when picture elements are arranged as shown in Fig. 1, if signal lines are along the column direction of picture elements as shown in Fig. 4, a picture of only R and B is shown on a certain signal line 1. Element electrodes are connected, and a certain signal line 3 is connected to only the pixel electrodes B and G. When a monochrome screen such as green is displayed on the display of this arrangement, the effective voltage of the signal voltage input to the signal line 1 and the signal line 3 is different. This difference in effective voltage of the signal line also affects the pixel electrode potential via the parasitic capacitance Csd between the signal line and the pixel electrode, and the potential of the pixel electrode Br connected to the signal line 1 The potential of the pixel electrode Br connected to the signal line 3 is not the same. For this reason, the difference in potential can cause vertical stripes (in the column direction of picture elements) to appear on the display, resulting in poor display quality. However, when the picture elements are arranged as shown in Fig. 3, the connection between the signal lines and the picture elements is as shown in Fig. 5, and R, G, B in multiple signal lines (both signal lines 1 and 3) Are connected evenly. Therefore, even when a monochrome screen is displayed, the effective voltages input to the plurality of signal lines are equal, and vertical stripe-shaped unevenness does not occur.
[0063] また、絵素を図 6のように配列させることもできる。図 6に示す絵素の配列は、列方向 の配列において R, B, Gが繰り返されている。また、行方向の配列において、同じ色 の絵素が 2つずつ繰り返される。このようになっていると、図 3に示す絵素の配列と同 様に、縦スジ状のムラが発生することない。また、図 2に示す絵素の配列と同様に、力 ラーフィルターを製造する際、 2つの絵素に対する色パターンを、 2つまとめて、ある いは、 2倍の大きさの 1つのパターンとして次々配置させていくことができる。よって、 カラーフィルターを効率よく製造することができる。 [0063] Also, the picture elements can be arranged as shown in FIG. In the pixel array shown in Fig. 6, R, B, and G are repeated in the array in the column direction. Also, the same color in the row direction array This picture element is repeated two times. In this way, vertical streak-like unevenness does not occur as in the picture element arrangement shown in FIG. Similarly to the picture element arrangement shown in Fig. 2, when manufacturing a power filter, two color patterns for two picture elements are combined or one pattern that is twice as large. You can arrange them one after another. Therefore, a color filter can be manufactured efficiently.
[0064] なお、図 2, 3, 6に示した絵素の配列を有するディスプレイパネルも、図 1 (b)で示 す視差バリアを用いることで、デュアルビュー表示を行うことができる。  Note that the display panel having the picture element arrangement shown in FIGS. 2, 3, and 6 can also perform dual view display by using the parallax barrier shown in FIG. 1 (b).
[0065] 上述した図 1 (a) ,図 2, 3, 6に示した絵素の配列は、次のように表現することもでき る。  The arrangement of picture elements shown in FIGS. 1 (a), 2, 3, and 6 can also be expressed as follows.
[0066] ここで、第 1方向用の異なる 3色の絵素、つまり第 1カラー画像を表示するための 3 原色絵素の集合を第 1絵素群、第 2方向用の異なる 3色の絵素、つまり第 2カラー画 像を表示するための 3原色絵素の集合を第 2絵素群と称することとする。  [0066] Here, the different three-color picture elements for the first direction, that is, the set of three primary color picture elements for displaying the first color image, is the first picture element group, the different three-color picture elements for the second direction. A set of three primary color picture elements for displaying a picture element, that is, a second color image is called a second picture element group.
[0067] 上記第 1及び第 2絵素群に属する各絵素は、第 1絵素群に属する絵素の列と第 2絵 素群に属する絵素の列とが交互に配列されるように行列状に配置されている。  [0067] For each picture element belonging to the first and second picture element groups, a sequence of picture elements belonging to the first picture element group and a series of picture elements belonging to the second picture element group are arranged alternately. Are arranged in a matrix.
[0068] さらに、上記第 1及び第 2絵素群に属する各絵素は、ある 2行 3列の絵素領域内(例 えば、図 1 (a)において R r、G 1、 B r、 B r、 R 1、 G rの配置された矩形の領域  [0068] Furthermore, each of the picture elements belonging to the first and second picture element groups is within a certain 2 × 3 picture element region (for example, R r, G 1, B r, Rectangular area where B r, R 1 and G r are placed

11 11 11  11 11 11
[0069] これにより、第 1及び第 2絵素群に属する 3原色絵素は、それぞれ 2行 3列の矩形の 領域内に収まるように配置されることになることから、これらは行方向 3絵素分の領域 に配置されることになるため、発明が解決しょうとする課題欄において説明した図 14 の構成(3原色絵素は行方向 5絵素分の領域に渡って配置される)と比較して、表示 の精細度の低下を抑制することができる。  [0069] As a result, the three primary color picture elements belonging to the first and second picture element groups are arranged so as to fall within a rectangular area of 2 rows and 3 columns, respectively. Since it is arranged in the area of picture elements, the configuration of Fig. 14 explained in the problem column to be solved by the invention (the three primary color picture elements are arranged over the area of five picture elements in the row direction) Compared with the above, it is possible to suppress a reduction in display definition.
