DISPLAY DEVICE WITH MIRROR FUNCTION
First Claim
1. A display device comprisinga display panel having a display area configured to produce a displayable first image;
- anda polarization conversion panel positioned on the display panel and operatively covering at least the display area of the display panel,wherein the polarization conversion panel includes;
a reflective polarizer positioned on the display panel;
a light-passing lower electrode(s) layer positioned on the reflective polarizer;
a light-passing upper electrode(s) layer spaced apart from and facing the lower electrode(s) layer;
liquid crystals positioned between the upper and lower electrodes,an absorptive polarizer positioned on the upper electrode; and
wherein at least one of the upper and lower electrode(s) layers is subdivided to include a respective plurality of sub-electrodes that are electrically separated from each other so as to be independently driveable by respective drive voltages.

Abstract
A display device includes a display panel and a polarization conversion panel disposed on the display panel. The polarization conversion panel has two or more display area regions that are independently drivable in order to implement either a reflection mode or transmissive mode in each of those regions and thus enabling pattern implementation. The polarization conversion panel includes: a reflective polarizer disposed on the display panel; an absorptive polarizer facing and spaced apart from the reflective polarizer; a lower electrode(s) layer disposed on the reflective polarizer; an upper electrode(s) layer disposed on the absorptive polarizer; and liquid crystals disposed between the upper and lower electrode layers. At least one of the upper and lower electrode layers includes a respective plurality of independently drivable sub-electrodes.
