Transflective liquid crystal display device, method of fabricating the same, and method of using the same
View Patent ↗A transflective liquid crystal display device includes a liquid crystal panel having a pixel electrode, wherein the pixel electrode includes a first reflective region and a first transmissive region, a patterned reflective panel adjacent to the liquid crystal panel, the patterned reflective panel having a second reflective region and a second transmissive region, and a back light unit adjacent to the patterned reflective panel, wherein the patterned reflective panel is movable along a direction parallel to the liquid crystal panel.
1. A transflective liquid crystal display device, comprising:
first and second substrates spaced apart and facing each other;
a thin film transistor on an inner surface of the first substrate;
a first passivation layer on the thin film transistor and having a first transmissive hole;
a transmissive electrode on the first passivation layer and electrically connected to the thin film transistor;
a second passivation layer on the transmissive electrode;
a reflector on the second passivation layer and having a second transmissive hole aligned with the first transmissive hole, the second transmissive hole defining a first transmissive region and a first reflective region;
a color filter layer on an inner surface of the second substrate;
a common electrode on the color filter layer;
a liquid crystal material layer between the reflector and the common electrode;
a first polarizer on an outer surface of the first substrate;
a patterned reflective panel over the first polarizer, the patterned reflective panel having a second transmissive region and a second reflective region;
a back light unit over the patterned reflective panel;
a diffusing film on an outer surface of the second substrate; and
a second polarizer on the diffusing film,
wherein the patterned reflective panel is movable along a direction parallel to the first and second substrates.
2. The device according to claim 1 , wherein the second transmissive region has an area larger than the second transmissive hole.
3. The device according to claim 1 , wherein the second reflective region has an area larger than the second transmissive hole.
4. The device according to claim 1 , wherein the first reflective region overlaps the second reflective region and the first transmissive region overlaps the second transmissive region.
5. The device according to claim 1 , wherein the first reflective region overlaps the second transmissive region and the first transmissive region overlaps the second reflective region.
6. The device according to claim 1 , wherein the reflector is electrically connected to the transmissive electrode.
7. The device according to claim 1 , wherein the first passivation layer includes one of benzocyclobutene (BCB) and acrylic resin.
