20100265441LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a transmissive or transflective liquid crystal display device in which interference fringes due to reflective light is suppressed and display qualities are improved.10-21-2010
20110012885LIQUID CRYSTAL DISPLAY DEVICE - In a transflective type liquid crystal display device of a vertical alignment mode in which liquid crystal domains exhibiting axisymmetric orientations are created, a difference in response speed between a region which presents display in the transmission mode and a region which presents display in the reflection mode is reduced.01-20-2011
20110019113LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a transflective liquid crystal display device having a high aperture ratio. The present invention is a liquid crystal display device, comprising: 01-27-2011
20110043438LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides an MVA transmissive or transflective liquid crystal display device with display qualities enhanced along with improvement in contrast.02-24-2011
20110141414LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a semi-transmissive liquid crystal display device that presents excellent display quality in the reflective display, and that can be easily applied to high definition. The liquid crystal display device of the present invention includes a first substrate, a liquid crystal layer, and a second substrate, in this order. The first substrate has pixel electrodes having a structure composed of a trunk portion and a plurality of branch portions that branch off from the trunk portion. The liquid crystal display device has a display region that includes a region where the branch portions and slits are alternately disposed. The display region has a reflective region and a transmissive region. The reflective region has a pixel electrode, a reflective film disposed under the pixel electrode, and a λ/4 retarder plate. The first best-fit curve, which is obtained from the gamma curve of the reflective display, is above the second best-fit curve, which is obtained from the gamma curve of the transmissive display, except in the regions where the reflectance of the first best-fit curve and the transmittance of the second best-fit curve are both 0% and 100%. The first best-fit curve does not have a gradation reversal and has an inflection point.06-16-2011
