Transflective liquid crystal display device having reflective and transparent pixel electrodes

A transflective liquid crystal display device comprising:

• first and second substrates opposing each other;
• liquid crystal material interposed between the first and second substrates;
• first and second electrodes, arranged in correspondence to the first and second substrates, respectively, to apply an electric field to the liquid crystal material;
• a plurality of reflective pixel electrodes being positioned between the liquid crystal material and the second substrate;
• a plurality of transparent pixel electrodes being positioned between the liquid crystal material and the second substrate;
• a color filter layer positioned between the first substrate and the liquid crystal material, the color filter layer having first portions aligned with the reflective pixel electrodes and second portions aligned with the transparent pixel electrodes;
• and
• a backlight device under the second substrate,
• wherein the reflective and transparent pixel electrodes form a mosaic-like pattern.

A transflective liquid crystal display device comprising:

• first and second substrates opposing each other;
• liquid crystal material interposed between the first and second substrates;
• a common electrode disposed between the first substrate and the liquid crystal material;
• gate lines and data lines disposed between the liquid crystal material and the second substrate, the gate lines and the data lines crossing each other to define pixel regions;
• reflective pixel electrodes positioned between the liquid crystal material and the second substrate, each reflective pixel electrode corresponding to a first pixel region;
• transparent pixel electrodes positioned between the liquid crystal material and the second substrate, each transparent pixel electrode corresponding to a second pixel region, wherein each of the first and second pixel regions includes only one of the group consisting of a reflective pixel electrode and a transparent pixel electrode;
• a color filter layer positioned between the first substrate and the liquid crystal material, the color filter layer having first portions aligned with the reflective pixel electrodes and second portions aligned with the transparent pixel electrodes;
• and
• a backlight device under the second substrate.
