Abstract
A light blocking member having variable transmittance, a display panel including the same, and a manufacturing method thereof. A light blocking member having a variable transmittance according to one exemplary embodiment includes a polymerizable compound, a binder, and a thermochromic material that exhibits a black color at a temperature below a threshold temperature and becomes transparent at a temperature above the threshold temperature.
Claims25
A light blocking member having a variable transmittance comprising:
- a polymerizable compound;
- a binder;
- and
- a thermochromic material that exhibits a black color at a temperature below a threshold temperature and becomes transparent at a temperature above the threshold temperature.
A display panel comprising:
- a substrate;
- a plurality of signal lines disposed on the substrate;
- a plurality of thin film transistors disposed on the substrate;
- a plurality of color filters disposed on the signal lines and the thin film transistors;
