Abstract:
1. A transflective liquid crystal display device having various cell gaps, comprising: a first substrate having a transmissive region and a reflective region thereon; an array of pixel driving elements formed on the first substrate in the reflective region; an insulating layer formed on the first substrate to cover the array of pixel driving elements; a passivation layer formed on the insulating layer in the reflective region, wherein a top surface of the passivation layer is higher than a top surface of the insulating layer; a conformal reflective electrode formed on the passivation layer, wherein the reflective electrode electrically connects the array of pixel driving elements; a conformal transparent electrode formed on the insulating layer, wherein the transparent electrode electrically connects the array of pixel driving elements; a color filter layer formed on the reflective electrode and the transparent electrode, wherein a first thickness of the color filter layer in the reflective region is smaller than a second thickness of the color filter layer in the transmissive region; a second substrate opposite the first substrate; a common electrode formed on an inner side of the second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; and a transparent organic element bridging a gap in the liquid crystal layer between the first substrate and the second substrate, formed on the common electrode in the reflective region, wherein one end of the transparent organic element shores up the color filter layer, thus a third thickness of the gap in the reflective region is smaller than a fourth thickness of the gap in the transmissive region.
