    摘要： The present invention provides a liquid crystal display device which can reduce the difference in brightness between an image obtained from a reflection region and an image obtained from a transmission region. The liquid crystal display device includes a pixel electrode and a counter electrode in each pixel region on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other with liquid crystal therebetween. The pixel region includes a transmission region and a reflection region. A gap between the pixel electrode and the counter electrode in the reflection region is set larger than the gap between the pixel electrode and the counter electrode in the transmission region.

    摘要： The present invention provides a display device which is capable of fetching input signals of a small amplitude into the inside thereof. A level converting circuit includes a first-conductive-type first transistor having a gate electrode to which input signals are applied through a first capacitive element, a second-conductive-type second transistor having a gate electrode to which input signals are applied through a second capacitive element, a first bias circuit which applies a first bias voltage to the gate electrode of the first transistor and a second bias circuit which applies a second bias voltage to the gate electrode of the second transistor. Here, the first bias voltage is a voltage which turns off the first transistor when a voltage applied to the gate electrode of the first transistor assumes a maximum value and the second bias voltage is a voltage which turns off the second transistor when a voltage applied to the gate electrode of the second transistor assumes a minimum value.
