Abstract
A heads-up display includes a thin-film transistor (TFT) panel, along with at least one reflective polarizer subassembly. Each of the at least one reflective polarizer subassembly includes a clear substrate having opposing first and second surfaces. The first surface is connected to the TFT panel, and the second surface has a polarizing film laminated thereto. The first surface of the clear substrate is textured, frosted, or the like such that when it is attached to the TFT panel it inhibits bonding between the clear substrate and the TFT panel that would cause optical defects.
