POLARIZING FILM ASSEMBLY, METHOD OF MANUFACTURING THE SAME AND DISPLAY DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polarizing film assembly that includes an acoustic output function being an acoustic unit and is small-sized, lightweight and improved in sound quality.

SOLUTION: A polarizing film assembly includes a polarizing film, a speaker film, a vibration improving layer, and a line member. The polarizing film includes a polarizer layer transmitting a vibrating component of light in parallel with an axis of polarization. The speaker film is disposed on the polarizing film to change an electric signal into a mechanical vibration to generate a sound. The vibration improving layer is interposed between the polarizing film and the speaker film to improve the mechanical vibration of the speaker film. The line member is electrically connected to the speaker film to transmit the electric signal.
