Wire grid polarizing plate and display device

摘要

A polarizing plate (5) includes a base layer (10), a buffer layer (35) and a plurality of conductive lattice lines (31). The buffer layer (35) is formed on the base layer (10). The conductive lattice lines are formed on the buffer layer in a stripe shape to reflect and polarize incident light. The buffer layer protects the conductive lattice lines. The conductive lattice lines include a silver (Ag) layer or an aluminum (Al) layer. Therefore, the buffer layer protects the conductive lattice lines, so that the lifetime of the polarizing plate may be increased. Furthermore, the display quality of a display panel and a display device having the polarizing plate may be enhanced.
