産業上の利用分野
本発明は液晶表示素子を用いた映像表示装装置に用いる
液晶表示素子用蛍光灯シールド板に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fluorescent lamp shield plate for a liquid crystal display element used in a video display device using a liquid crystal display element.

化され、プリント基板上における蛍光灯回路の占める面
積比率は増大し、とりわけ、蛍光灯反射傘の占める面積
比率が増大している傾向にある。6 Conventional technologies: Video display devices using liquid crystal display elements have become smaller. The area occupied by the fluorescent lamp circuit on the printed circuit board has increased, and in particular, the area occupied by the fluorescent lamp reflector has increased. There is a tendency to do so.
この様な状況において反射傘とプリント基板間に回路を
配置し、プリント基板上の蛍光灯回路の面積比率を下げ
、プリント基板を小形化することが急務とされている。Under these circumstances, there is an urgent need to arrange a circuit between the reflector and the printed circuit board, reduce the area ratio of the fluorescent lamp circuit on the printed circuit board, and downsize the printed circuit board.
以下に従来の液晶表示素子用蛍光灯シールド板について
説明する。A conventional fluorescent lamp shield plate for a liquid crystal display element will be explained below.

。In a liquid crystal display element using a fluorescent lamp shield plate for a liquid crystal display element constructed as described above, a member in which the reflective umbrella 1 and the fluorescent lamp shield plate 2 are integrated is used, and this member is brought into contact with a printed board. It is configured to be fixed like this.
発明が解決しようとする課題
しかしながら、上記の従来の構成では、反射傘と蛍光灯
シールド板をプリント基板に接する様に取シけけるため

工数が増すという欠点を有している。Problems to be Solved by the Invention However, in the conventional configuration described above, since the reflector and fluorescent lamp shield plate can be removed so as to be in contact with the printed circuit board, it is necessary to place the components on the printed circuit board under the reflector. Since it is impossible to do so, the printed circuit board area of the reflector portion cannot be used effectively, resulting in a disadvantage that the printed circuit board becomes large. Also, when soldering the shield plate to the printed circuit board, it is necessary to darken the reflector after the flow soldering process to prevent it from deforming due to heat.
This method has the disadvantage of increasing the number of man-hours.

蛍光灯シールド板を提供することを目的とする。The present invention solves the above-mentioned conventional problems, and allows components to be placed on a printed circuit board under a reflective umbrella, and also allows the mounting of fluorescent lamp shield plates to be carried out in the flow-end process. The purpose of the present invention is to provide a fluorescent lamp shielding plate for a liquid crystal display element that is capable of being attached with a thin plate.
