PURPOSE:To evenly and uniformly adhere a polarizing plate to a liquid crystal cell and to allow the joining without generating defects, such as unequal colors of a display and contingent remaining of bubbles, by pressing the polarizing plate via a tacky adhesive to the liquid crystal cell surface by a pressing chamber constituted of a flexible wall material, thereby sticking the polarizing plate to the liquid crystal cell. CONSTITUTION:The pressing chamber 4 is formed by using a soft material, such as silicone rubber, and is supported to a chamber support 5. Gas or liquid of a high temp. and high pressure is filled in the chamber 4 and the polarizing plate 2 is pressed to the liquid crystal cell 1 surface from the opposite side of the polarizing plate in the case of sticking the polarizing plate 2 to the liquid crystal cell 1. The pressurization is executed gradually from the central part to the outer edge part of the polarizing plate 2 at this time, by which the polarizing plate 2 and the liquid crystal cell 1 are stuck and the coloring and the remaining of the bubbles by the unequal pressure at the time of the sticking are prevented. The excess pressure on the liquid crystal cell 1 is absorbed by the resilience of the wall material of the chamber 4 and the high- quality liquid crystal display element is produced. |
