Description of the Related Art Conventionally, as a display device mounted on a television receiver, an information device, or the like, a liquid crystal display device using a display liquid crystal panel (LCD; Liquid Crystal Display, hereinafter abbreviated as “LCD”) is known. Yes. With respect to display devices such as liquid crystal display devices, two screens that provide a first image in a first observation area and a second image in a second observation area with the recent diversification of information equipment and the like The display is known.

次に、２画面表示を行う従来例に係る表示装置について、図面を参照して説明する。図５は、従来例に係る表示装置を説明する断面図である。図５に示すように、第１の画像を表示する第１の画素列１０Ａと第２の画像を表示する第２の画素列１０Ｂとが交互に配置されてなる表示パネル１０が配置されている。ここで、第１及び第２の画素列１０Ａ，１０Ｂは、例えば液晶層を備えた画素からなる。また、第１及び第２の画素列１０Ａ，１０Ｂの各画素間には、いわゆるブラックマトリクス１１が形成されている。そして、表示パネル１０の上方には、不図示のガラス基板等の透明基板を介して、遮光機能を有した金属もしくは樹脂等からなる遮光板４０が配置されている。遮光板４０は、第１の画素列１０Ａ及び第２の画素列１０Ｂに対して平行に交互に延びる遮光部４１及び開口部４２を備えている。   Next, a conventional display device that performs two-screen display will be described with reference to the drawings. FIG. 5 is a cross-sectional view illustrating a display device according to a conventional example. As shown in FIG. 5, a display panel 10 is arranged in which first pixel columns 10A that display a first image and second pixel columns 10B that display a second image are alternately arranged. . Here, the first and second pixel columns 10A and 10B are composed of pixels including a liquid crystal layer, for example. Also, a so-called black matrix 11 is formed between the pixels of the first and second pixel columns 10A and 10B. A light shielding plate 40 made of metal or resin having a light shielding function is disposed above the display panel 10 via a transparent substrate such as a glass substrate (not shown).

As shown in FIG. 5, the first image from the first pixel row 10 </ b> A passes through the opening 42 of the light shielding plate 40 in the first observation region A that is leftward from the position C directly in front of the display panel 10. Provided. At this time, the second image of the second pixel row 10B is not provided to the first observation area A because it is blocked by the light blocking portion 41 of the light blocking plate 40.

一方、表示パネル１０の真正面の位置Ｃから右方向に離れた第２の観察領域Ｂには、遮光板４０の開口部４２を通して第２の画素列１０Ｂから第２の画像が提供される。このとき、第１の画素列１０Ａの第１の画像は、遮光板４０の遮光部４１により遮られるため、第２の観察領域Ｂには提供されない。こうして、第１の観察領域Ａに第１の画像を提供し、第２の観察領域Ｂに第２の画像を提供する２画面表示が行われる。   On the other hand, a second image is provided from the second pixel row 10B through the opening 42 of the light shielding plate 40 to the second observation region B that is separated from the position C in front of the display panel 10 in the right direction. At this time, the first image of the first pixel row 10 </ b> A is not provided to the second observation region B because it is blocked by the light blocking portion 41 of the light blocking plate 40.

しかしながら、上述した表示装置による２画面表示では、表示パネル１０を、その真正面の位置Ｃ及びその近傍から観察した場合、第１及び第２の画像が重畳してなる２重像が発生していた。即ち、第１の画像と第２の画像との識別ができなくなり、２画面表示の表示品位が低下していた。   However, in the two-screen display by the above-described display device, when the display panel 10 is observed from the position C in front of the display panel 10 and the vicinity thereof, a double image is generated in which the first and second images are superimposed. . That is, the first image and the second image cannot be distinguished from each other, and the display quality of the two-screen display is lowered.

そこで本発明は、第１の観察領域に第１の画像を提供し、第２の観察領域に第２の画像を提供する表示装置において、第１及び第２の画像からなる２重像を抑止するものである。   Therefore, the present invention suppresses a double image composed of the first and second images in a display device that provides the first image in the first observation region and provides the second image in the second observation region. To do.

And a light shielding plate having a light shielding portion and an opening that alternately and alternately extend in parallel, and the distance between the first observation region and the second observation region and the light shielding plate is D, and the light shielding plate and the display panel When the distance between and G is G, the width of the opening of the light shielding plate is K, and the width of the black matrix is Q, K ≦ Q × D / (D + G) is satisfied. Further, when the width of the first observation region and the second observation region is V and the pitch between the first pixel column and the second pixel column is P, P = G × V / D is satisfied. And In addition, the light-shielding portion is arranged so that a line connecting a point on the front side of the display panel and the black matrix passes through the opening.

本発明の表示装置によれば、第１の観察領域に第１の画像を提供し、第２の観察領域に第２の画像を提供する表示装置において、表示パネルを、その真正面の位置から観察した場合における第１及び第２の画像からなる２重像を抑止し、従来例に比して２画面表示の表示品位を向上させることができる。   According to the display device of the present invention, in the display device that provides the first image in the first observation region and provides the second image in the second observation region, the display panel is observed from the position in front of the display panel. In this case, the double image composed of the first and second images can be suppressed, and the display quality of the two-screen display can be improved as compared with the conventional example.

次に、本発明の実施形態に係る表示装置について図面を参照して説明する。図１は、本発明の実施形態に係る表示装置を説明する平面図である。図１（Ａ）及び図１（Ｂ）には、それぞれ、後述する表示パネル１０、それに重畳する遮光板３０が別個に示されている。また、図２は、図１のＸ−Ｘ線に沿った断面図である。即ち、図２では、後述する第１の画素列１０Ａ及び第２の画素列１０Ｂと直交する方向の断面を示している。なお、図１及び図２では、図５に示したものと同一の構成要素については同一の符号を付して説明を行うものとする。   Next, a display device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view for explaining a display device according to an embodiment of the present invention. 1A and 1B respectively show a display panel 10 described later and a light shielding plate 30 overlapping therewith. 2 is a cross-sectional view taken along line XX in FIG. That is, FIG. 2 shows a cross section in a direction orthogonal to a first pixel column 10A and a second pixel column 10B described later. In FIG. 1 and FIG. 2, the same components as those shown in FIG.

図１及び図２に示すように、第１の画像を表示する第１の画素列１０Ａと第２の画像を表示する第２の画素列１０Ｂとが交互に配置されてなる表示パネル１０が配置されている。第１及び第２の画素列１０Ａ，１０Ｂの各画素間には、いわゆるブラックマトリクス１１が配置されている。ここで、第１及び第２の画素列１０Ａ，１０Ｂは、例えば液晶層を備えた画素からなる。もしくは、第１及び第２の画素列１０Ａ，１０Ｂは、液晶層を備えた画素に限定されず、その他の画素、例えば有機エレクトロルミネセンス素子を発光素子として備えた画素からなるものであってもよい。   As shown in FIGS. 1 and 2, a display panel 10 is arranged in which first pixel columns 10A for displaying a first image and second pixel columns 10B for displaying a second image are alternately arranged. Has been. A so-called black matrix 11 is arranged between the pixels of the first and second pixel columns 10A and 10B. Here, the first and second pixel columns 10A and 10B are composed of pixels including a liquid crystal layer, for example. Alternatively, the first and second pixel rows 10A and 10B are not limited to pixels having a liquid crystal layer, and may be composed of other pixels, for example, pixels having an organic electroluminescence element as a light emitting element. Good.

表示パネル１０の上方には、不図示のガラス基板等の透明基板を介して、遮光機能を有した金属もしくは樹脂等からなる遮光板３０が配置されている。遮光板３０は、第１の画素列１０Ａ及び第２の画素列１０Ｂに対して平行に交互に延びる遮光部３１及び開口部３２を備えている。   A light shielding plate 30 made of metal or resin having a light shielding function is arranged above the display panel 10 via a transparent substrate such as a glass substrate (not shown). The light shielding plate 30 includes light shielding portions 31 and openings 32 that alternately extend in parallel to the first pixel row 10A and the second pixel row 10B.

また、表示パネル１０の真正面の位置Ｃの左側に第１の観察領域Ａが存在し、表示パネル１０の真正面の位置Ｃの右側に第２の観察領域Ｂが存在している。表示パネル１０の真正面の位置Ｃとは、第１及び第２の画素列１０Ａ，１０Ｂと直交する方向で表示パネル１０を略２分割する線上の鉛直線上の位置もしくはその近傍を意味する。   In addition, the first observation area A exists on the left side of the position C in front of the display panel 10, and the second observation area B exists on the right side of the position C in front of the display panel 10. The position C directly in front of the display panel 10 means a position on a vertical line on a line that divides the display panel 10 into two substantially in the direction orthogonal to the first and second pixel columns 10A and 10B or the vicinity thereof.

次に、表示パネル１０と遮光板３０の詳細な構成について説明する。図２に示すように、遮光板３０の遮光部３１は、表示パネル１０の真正面の位置Ｃとブラックマトリクス１１とを結ぶ線が開口部３２を通過するように配置されている。   Next, detailed configurations of the display panel 10 and the light shielding plate 30 will be described. As shown in FIG. 2, the light shielding portion 31 of the light shielding plate 30 is arranged so that a line connecting the position C directly in front of the display panel 10 and the black matrix 11 passes through the opening 32.

ここで、第１の観察領域Ａ及び第２の観察領域Ｂと、遮光板３０との間の距離をＤとする。また、遮光板３０と表示パネル１０との間の距離をＧとする。また、遮光板３０の開口部３２の幅をＫとし、表示パネル１０のブラックマトリクス１１の幅をＱとする。このとき、表示パネル１０及び遮光板３０は、式１を満たすように形成されている。式１は、表示パネル１０の真正面の位置Ｃにおいて、遮光板３０の開口部３２を通してブラックマトリクス１１のみが観察されて黒表示となるための条件である。
Ｋ ≦ Ｑ×Ｄ／（Ｄ＋Ｇ） ・・・（１） Here, the distance between the first observation region A and the second observation region B and the light shielding plate 30 is D. Further, G is a distance between the light shielding plate 30 and the display panel 10. The width of the opening 32 of the light shielding plate 30 is K, and the width of the black matrix 11 of the display panel 10 is Q. At this time, the display panel 10 and the light shielding plate 30 are formed so as to satisfy Expression 1. Formula 1 is a condition for only the black matrix 11 to be observed through the opening 32 of the light shielding plate 30 at a position C in front of the display panel 10 to achieve black display.
K ≦ Q × D / (D + G) (1)

ただし、開口部３２の幅Ｋが著しく小さく決定されると、第１及び第２の観察領域Ａ，Ｂにおける第１及び第２の画像の輝度が低下して、それらの画像の視認に支障をきたす。そこで、開口部３２の幅Ｋの下限値は、第１及び第２の観察領域Ａ，Ｂにおいて、第１及び第２の画像の視認に支障をきたさないような輝度が得られる値として決定されるものとする。   However, if the width K of the opening 32 is determined to be extremely small, the luminance of the first and second images in the first and second observation areas A and B is lowered, which hinders the visual recognition of those images. Come on. Therefore, the lower limit value of the width K of the opening 32 is determined as a value with which brightness is obtained in the first and second observation areas A and B so as not to hinder the visual recognition of the first and second images. Shall be.

次に、式１が得られる理由について図面を参照して説明する。図３は、図２の表示パネル１０のブラックマトリクス１１と遮光板３０の開口部３２との配置関係を説明する概念図である。   Next, the reason why Formula 1 is obtained will be described with reference to the drawings. FIG. 3 is a conceptual diagram illustrating an arrangement relationship between the black matrix 11 of the display panel 10 of FIG. 2 and the opening 32 of the light shielding plate 30.

図３に示すように、開口部３２の幅Ｋを底辺とし、その底辺に対向する頂点を位置Ｃとすると、三角形ＣＬＭ（以降、△ＣＬＭと略称する）が得られる。また、ブラックマトリクス１１の幅Ｑを底辺とし、その底辺に対向する頂点を位置Ｃとすると、三角形ＣＳＴ（以降、△ＣＳＴと略称する）が得られる。   As shown in FIG. 3, a triangle CLM (hereinafter abbreviated as ΔCLM) is obtained when a width K of the opening 32 is a base and a vertex facing the base is a position C. Further, assuming that the width Q of the black matrix 11 is the base and the vertex facing the base is the position C, a triangle CST (hereinafter abbreviated as ΔCST) is obtained.

表示パネル１０の真正面の位置Ｃにおいて、開口部３２を通してブラックマトリクス１１のみが観察されるためには、開口部３２の幅Ｋは、△ＣＬＭ及び△ＣＳＴが相似となるような値であるか、それよりも小さい値である。そこで、△ＣＬＭ及び△ＣＳＴが相似である場合を考えると、幅Ｋに対する幅Ｑの比は辺ＣＬに対する辺ＣＳの比と等しい。また、このとき、辺ＣＬに対する辺ＣＳの比は、距離Ｄに対する距離Ｄ及び距離Ｇの総和の比と等しい。即ち、△ＣＬＭ及び△ＣＳＴが相似であれば式２が得られる。さらに式２を基に幅Ｋの値を求めると、その値以下となる幅Ｋのとりうる範囲は、式１として表される。
Ｋ：Ｑ ＝ Ｄ：（Ｄ＋Ｇ） ・・・（２） In order for only the black matrix 11 to be observed through the opening 32 at the position C in front of the display panel 10, the width K of the opening 32 is a value that makes ΔCLM and ΔCST similar to each other. It is a smaller value. Therefore, considering the case where ΔCLM and ΔCST are similar, the ratio of the width Q to the width K is equal to the ratio of the side CS to the side CL. At this time, the ratio of the side CS to the side CL is equal to the ratio of the sum of the distance D and the distance G to the distance D. That is, if ΔCLM and ΔCST are similar, Equation 2 is obtained. Further, when the value of the width K is obtained based on the expression 2, a possible range of the width K that is equal to or less than the value is expressed as an expression 1.
K: Q = D: (D + G) (2)

また、図２に示すように、第１の観察領域Ａ及び第２の観察領域Ｂの幅をＶとし、第１の画素列１０Ａ及び第２の画素列１０ＢのピッチをＰとするとき、表示パネル１０は、式３を満たすように形成されている。
Ｐ ＝ Ｇ×Ｖ／Ｄ ・・・（３） Further, as shown in FIG. 2, when the width of the first observation region A and the second observation region B is V and the pitch of the first pixel column 10A and the second pixel column 10B is P, the display The panel 10 is formed to satisfy Equation 3.
P = G × V / D (3)

なお、式３は、式４の幾何学的関係から導かれたものである。
Ｐ：Ｖ＝Ｇ：Ｄ ・・・（４） Equation 3 is derived from the geometric relationship of Equation 4.
P: V = G: D (4)

次に、上記構成により２画面表示が実現される仕組みについて図面を参照して説明する。図２に示すように、表示パネル１０の真正面の位置Ｃに対しては、第１の画素列１０Ａの第１の画像、及び第２の画素列１０Ｂの第２の画像は、いずれも遮光部３１により遮られるため提供されない。即ち、表示パネル１０の真正面の位置Ｃでは、ブラックマトリクス１１のみが観察されるため、黒表示となる。これは、表示パネル１０の真正面の位置Ｃとブラックマトリクス１１とを結ぶ線が開口部３２を通過することと、式１の関係が満たされていることによる。なお、図示しないが、式１の左辺、即ち開口部３２の幅Ｋが右辺より小さくなる場合（即ち両辺が等しくない場合）、上記黒表示となる領域は、表示パネル１０の真正面の位置Ｃのみならず、その近傍にも存在する。   Next, a mechanism for realizing two-screen display with the above configuration will be described with reference to the drawings. As shown in FIG. 2, for the position C in front of the display panel 10, the first image in the first pixel column 10A and the second image in the second pixel column 10B are both light-shielding portions. Since it is blocked by 31, it is not provided. That is, at the position C in front of the display panel 10, only the black matrix 11 is observed, so that black display is obtained. This is because the line connecting the position C in front of the display panel 10 and the black matrix 11 passes through the opening 32 and the relationship of Expression 1 is satisfied. Although not shown, when the left side of Equation 1, that is, when the width K of the opening 32 is smaller than the right side (that is, when both sides are not equal), the black display region is only the position C directly in front of the display panel 10. It also exists in the vicinity.

また、第１の観察領域Ａには、式３の関係により、開口部３２を通して、第１の画素列１０Ａから第１の画像が提供される。このとき、第２の画素列１０Ｂの第２の画像は、遮光部３１により遮られるため、第１の観察領域Ａには提供されない。   Further, the first image is provided from the first pixel column 10A to the first observation region A through the opening 32 according to the relationship of Expression 3. At this time, the second image of the second pixel row 10B is not provided to the first observation region A because it is blocked by the light shielding unit 31.

一方、第２の観察領域Ｂには、開口部３２を通して、式３の関係により、第２の画素列１０Ｂから第２の画像が提供される。このとき、第１の画素列１０Ａの第１の画像は、遮光部３１により遮られるため、第２の観察領域Ｂには提供されない。   On the other hand, in the second observation region B, the second image is provided from the second pixel column 10B through the opening 32 according to the relationship of Expression 3. At this time, the first image of the first pixel column 10 </ b> A is not provided to the second observation region B because it is blocked by the light shielding unit 31.

こうして、表示パネル１０の２画面表示が実現されると共に、表示パネル１０の真正面の位置Ｃにおいて、もしくは位置Ｃ及びその近傍において、従来例にみられたような第１の画像及び第２の画像からなる２重像を抑止することができる。結果として、従来例に比して２画面表示の表示品位を向上させることができる。   In this way, two-screen display of the display panel 10 is realized, and the first image and the second image as seen in the conventional example at the position C directly in front of the display panel 10 or at the position C and its vicinity. The double image which consists of can be suppressed. As a result, the display quality of the two-screen display can be improved as compared with the conventional example.

なお、上記実施形態の表示パネル１０及び遮光板３０は、上記構成に限定されず、少なくとも上記と同等の効果を奏するものであれば、下記のように配置されてもよい。図４は、本発明の実施形態に係る表示装置を説明する平面図である。図４（Ａ）及び図４（Ｂ）は、それぞれ、表示パネル１０、それに重畳する遮光板３０Ｇが別個に示されている。   In addition, the display panel 10 and the light shielding plate 30 of the above embodiment are not limited to the above-described configuration, and may be arranged as follows as long as at least the same effect as described above can be obtained. FIG. 4 is a plan view illustrating the display device according to the embodiment of the present invention. 4A and 4B respectively show the display panel 10 and the light shielding plate 30G overlapping therewith.

図４（Ａ）に示すように、第１の画素列１０Ａ及び第２の画素列１０Ｂは、それぞれ、さらに複数の行単位に区分され、各行で交互に配置されてもよい。さらに、このときの第１の画素列１０Ａ及び第２の画素列１０Ｂに対応して、図４（Ｂ）に示すように、遮光板３０Ｇの遮光部３１及び開口部３２は、行単位に区分され、各行で交互に配置されてもよい。これにより、観察される第１及び第２の画像が列単位のみならず行単位にも交互に存在するため、２画面表示の際の視認性をさらに向上させることができる。   As shown in FIG. 4A, the first pixel column 10A and the second pixel column 10B may be further divided into a plurality of row units, and may be alternately arranged in each row. Further, corresponding to the first pixel column 10A and the second pixel column 10B at this time, as shown in FIG. 4B, the light shielding part 31 and the opening 32 of the light shielding plate 30G are divided into rows.
