摘要： An inverter includes an input inverter having a high-resistance load and a first transistor and an output buffer including second and third transistors coupled in series. A power supply voltage is provided to satisfy an inequality VDD1>VDD2+Vth where VDD1 is the power supply voltage of the input inverter, VDD2 is the power supply voltage of the output buffer, and Vth is the threshold voltage of the transistors. Use of the high-resistance load allows an output waveform to rise and fall quickly, as well as reduces current consumption.

摘要： There is disclosed a transflective liquid crystal display device having reflective portions having an improved contrast ratio. At each subpixel of the display device, a pixel electrode is shared between transmissive and reflective portions. Independent counter electrodes are used respectively for the transmissive and reflective portions. Different potentials are applied to the counter electrodes for the transmissive and reflective portions. The transmissive portion operates in normally black mode. That is, the transmissive portion displays black when no voltage is applied. The reflective portion operates in normally white mode. That is, the reflective portion displays white when no voltage is applied. The liquid crystal layer in the reflective portion is thicker than the liquid crystal layer in the transmissive portion.
