Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate opposite to the first substrate, the second substrate comprising a bottom surface having a plurality of recesses arranged in a plurality of groups and a plurality of shallow gaps defined thereat, a plurality of reflection layers filled in the recesses and the shallow gaps, the groups of the recesses being evenly spaced apart from each other with a distance separating adjacent groups of recesses being equal to a width of each group of recesses, the recesses in each group of recesses being evenly spaced apart from each other, but connected with one another by the shallow gaps, a width of each recess being equal to a width of each shallow gap; a liquid crystal layer between the first and second substrates; a plurality of pixel regions adjacent each other and each spanning through the first substrate, the liquid crystal layer, and the second substrate, each pixel region comprising a reflection region and a transmission region; and a backlight module disposed adjacent to the second substrate; Wherein the reflection regions correspond to portions of the bottom surface of the second substrate having the reflection layers, and the transmission regions correspond to portions of the bottom surface of the second substrate that do not have the reflection layers.
