Abstract

This describes the mechanically thinning process for a cell assembly used for liquid crystal displays. In this process, the thickness of cell is to be reduced by the means of mechanical polishing technique just before the polarizer attach process. Prior to the mechanical polishing, all of the driver pads on the surface of TFT glass are covered with resin material in order to protect from being physically and chemically damaged by abrasives used in the mechanical polishing process. This resin material,calledprotect seal, is removed after the mechanical polishing. The invented process flow is show in figure 1. seal cell assem bly
