Abstract
A sub-pixel of a liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer formed between the first and second substrates. A color filter layer is formed on the first substrate and includes a first photoresist formed on a transparent region and a reflective region of the sub-pixel for blocking light of wavelengths outside a first range, a second photoresist formed on the reflective region of the sub-pixel for blocking light of wavelengths outside a second range that is different from the first range, and an intermediate area formed between and free of the first and second photoresists.

A sub-pixel of a transflective liquid crystal display panel, said sub-pixel comprising:
- a first substrate;
- a color filter layer formed on the first substrate comprising:
- a first photoresist formed in a transparent region and a reflective region of the sub-pixel for filtering out light of wavelengths outside a first range;
- a second photoresist formed in the reflective region of the sub-pixel for filtering out light of wavelengths outside a second range which is different from the first range;
- and
- an intermediate area formed between and free of the first photoresist and the second photoresist;
- a second substrate opposed to the first substrate;
- and
- a liquid crystal layer formed between the first substrate and the second substrate.
A liquid crystal display, comprising:
- a transflective liquid crystal display panel comprising:
- a first substrate;
- a color filter layer formed on the first substrate;
- a second substrate opposed to the first substrate;
- and
- a liquid crystal layer formed between the first substrate and the second substrate;
- and
- wherein said panel is divided into a plurality of sub-pixels at least one of which comprises, in the color filter layer:
- a first photoresist formed in a transparent region and a reflective region of said sub-pixel for filtering out light of wavelengths outside a first range;
- a second photoresist formed in the reflective region of said sub-pixel for filtering out light of wavelengths outside a second range which is different from the first range;
- and
- an intermediate area formed between and free of the first photoresist and the second photoresist;
- and
- a backlight module for providing light to the transparent regions of the sub-pixels.
