の大きさを製造するのが限度であり、壁掛けテレ
ビジヨンとしては、小型パネルを複数枚連結し大
型化している現状である。 However, the size of the liquid crystal panels used in this type of transmissive liquid crystal matrix display device is limited to about 5 inches, and wall-mounted televisions are currently made larger by connecting multiple small panels. It is.
ところが、この場合には第１図に示す如く、接
続部には液晶駆動用画素がなく、液晶パネルを駆
動した場合、接続用スペーサ３が見えてしまう。 However, in this case, as shown in FIG. 1, there is no pixel for driving the liquid crystal in the connection part, and when the liquid crystal panel is driven, the connection spacer 3 becomes visible.
又、接続用スペーサ３を透明にした場合も裏面
の光源が見え、画素表示には不適当となる。 Furthermore, even if the connection spacer 3 is made transparent, the light source on the back side can be seen, making it unsuitable for pixel display.
本発明は、上記の問題点である、接続部の表示
不可能な部分の表示方法を改善し、接続部の見え

様にする事が可能である。 Specifically, by arranging a lens or a prism at the connection part of the liquid crystal panel, it is possible to make the connection spacer invisible and to make the inside of the liquid crystal panel visible due to the refraction effect of the lens or prism.
以下第２図、第３図、第４図を用いて本発明の
一実施例を説明する。 An embodiment of the present invention will be described below with reference to FIGS. 2, 3, and 4.

設置する。 FIG. 2 is a sectional view of a transmissive liquid crystal matrix display device according to the present invention. A connection spacer 13 is sandwiched between the transmissive display panels 11 and 11',
Connection is made using the connection terminal 12. Next prism 1
4 is installed at the center of the connection between the transmissive display panels 11 and 11' so that light can be dispersed when viewed from the observation point 15.
この様に接続部にプリズムを設置した、透過型
液晶マトリツクス表示装置を駆動した場合、接続
スペーサ１３は観察できない。 When driving a transmissive liquid crystal matrix display device in which a prism is installed at the connection portion in this manner, the connection spacer 13 cannot be observed.

観える状態を修正出来る為である。 By reducing the pitch of the thin film transistor array near the panel ends, that is, near the panel connections, more accurate image display can be achieved when observed through the prism 24. This is because the light passing through the prism is dispersed, so it is possible to correct the situation in which the pixels appear stretched.
第４図は、本発明による第３の実施例であり、

小型化が可能であり、画像の歪も少なく出来る。 The lens 34 is installed so that the center of the lens is located at the center of the connection part, and is made in a shape that becomes thinner toward both ends. When driving a transmissive liquid crystal matrix display device equipped with such a lens, the connection spacer 33 cannot be seen. In this case, the lens can be made smaller and image distortion can be reduced.
