Abstract
A touch display device includes an upper polarizer, a display unit and a touch sensing unit. The upper polarizer allows light having a first linear polarization direction to pass therethrough and blocks light having a second linear polarization direction. The second linear polarization direction is perpendicular to the first linear polarization direction. The display unit is spaced-apart from the upper polarizer and is used to display images. The touch sensing unit is disposed between the upper polarizer and the display unit, and includes an optical compensation substrate and a touch sensing electrode structure disposed on the optical compensation substrate. The optical compensation substrate is flexible and is able to control the polarization property of the light passing therethrough.
