摘要： A reflective layer for reflecting light incident from a second substrate side and transmitting through a second electrode made of ITO or the like is formed above a first substrate, a switching element provided for each pixel, and an insulating film covering the switching element, the reflective layer being insulated from the switching element. A first electrode having a work function similar to the second electrode and made of a transparent conductive material such as ITO is formed more proximate to a liquid crystal layer than is the reflective layer and is connected to the switching element. The thickness of the first electrode is set to 100 Å or less or in a range approximately from 750 Å to 1250 Å. Alternatively, the switching element maybe connected to the reflective electrode, the first electrode and the reflective electrode which are formed with an insulating film therebetween may be capacitively coupled, and the first electrode may be driven by the reflective electrode via the capacitor.

摘要： On a first substrate are formed a TFT provided to each pixel, an insulating film which covers the TFT, and a reflective layer which is provided on the insulating film so as to be insulated from the TFT and reflects light incident from a second substrate side. The reflective layer is covered with a passivation film on which a first electrode made of a transparent conductive material, such as ITO having the work function equivalent to a second electrode, is formed and connected to the TFT. The passivation film covering the reflective layer prevents the reflective surface of the reflective layer from deteriorating in reflection properties during a process for connecting the TFT and the first electrode. Further, the first and second electrodes having similar characteristics can symmetrically AC drive the liquid crystal layer.

摘要： An LCD apparatus having a liquid crystal layer sealed between a first substrate having a first electrode and a second substrate having a second electrode, wherein the first substrate comprises a reflective layer formed only in a subregion within a pixel region, for reflecting light. A transparent conductive material is used for the first electrode and the first electrode made of the transparent conductive material is layered to cover a transmissive region within a pixel region and over the reflective layer in a reflective region within the pixel region to directly cover the reflective layer. Optimum cell gaps dr and dt are set in the reflective and the transmissive regions, respectively, based on a twist angle, which is a difference between the alignment directions of liquid crystal at the side of the first electrode and of liquid crystal at the side of the second electrode so that an optimum reflectivity and an optimum transmittance are realized in each region to allow enhancements in the quality of a transflective LCD. A configuration may be employed in which a switching element is formed over the first substrate and the reflective layer is placed in the reflective region of a pixel region on an insulating film which covers the switching element, the reflective layer being insulated from the switching element, the work functions for the first electrode and for the second electrode are similar.
