WIPO Patent Application WO/2018/178795
Kind Code:
A1
Abstract:
Provided is a display device having a high contrast ratio. The display device includes a first liquid crystal panel (20A) and a second liquid crystal panel (10A). Light that has passed through the first liquid crystal panel (20A) is incident to the second liquid crystal panel (10A). The second liquid crystal panel (10A) displays an image by selectively allowing light to pass therethrough. The first liquid crystal panel (20A) and the second liquid crystal panel (10A) operate in mutually different modes. For example, the first liquid crystal panel (20A) operates in TN mode, and the second liquid crystal panel (10A) operates in IPS mode or FFS mode.
