A large number of polarizing plates 2 are continuously arranged on the upper side and wound around a reel 3. In both figures above, 4
Is a polarizing plate, and 5 is a liquid crystal cell.
＜発明が解決しようとする問題点＞ しかしながら、上記従来の技術では、液晶表示素子が
大型化し、それに応じて偏光板が大型化するに従って、
リールに巻く時のカール性や、リール径が大きくなりす
ぎる事による、１リール当りの偏光板数の減少により、
交換時間の増加や、巻き取り時の巻き圧を大きくしなけ
ればならないために偏光板ノリ面の凹凸が発生しやすく
なるという問題点があった。<Problems to be Solved by the Invention> However, in the above-described conventional technique, as the liquid crystal display element becomes larger and the polarizing plate becomes larger accordingly,
Due to curling when wound on a reel and the number of polarizing plates per reel due to the reel diameter becoming too large,
There is a problem that unevenness of the polarizing plate warp surface is likely to occur because the replacement time must be increased and the winding pressure at the time of winding must be increased.
本発明は、従来の技術に於ける上記問題点を解決すべ
くなされたものである。The present invention has been made to solve the above problems in the conventional technology.
＜問題点を解決するための手段＞ 偏光板供給源より順次供給される偏光板を、順次液晶

ける。<Means for Solving Problems> In a polarizing plate sticking device that sequentially sticks polarizing plates sequentially supplied from a polarizing plate supply source to a liquid crystal cell, a large number of polarizing plates connected by a connecting member. A polarizing plate supply source is provided in which the connected body of (1) is appropriately folded and housed in a housing case.
＜実施例＞ 以下、実施例に基づいて本発明を説明にする。<Examples> Hereinafter, the present invention will be described based on Examples.
第１図は本発明の一実施例に於ける特徴部分の概略構

載、貼付される。The polarizing plates 12, ... Which have been continuously taken out from the storage case 14 by the carrier tape 11 are transferred and attached to the surface of the liquid crystal cell 15.
第４図は、偏光板供給源の他の構成例である。 FIG. 4 shows another configuration example of the polarizing plate supply source.
なお、輸送・保管時には、偏光板が縦になるように、
収納ケースを保持することにより（収納ケースに上下を
明記しておく）、垂直に積み重ねた場合に発生しやすい
偏光板ノリ面の凹凸を防止することができる。In addition, during transportation and storage, make sure that the polarizing plate is vertical.
By holding the storage case (the top and bottom are clearly marked on the storage case), it is possible to prevent unevenness of the polarizing plate surface which tends to occur when vertically stacked.
