Liquid crystal display apparatus having a non-linear resistor connected to the pixel electrode and using a two-terminal device as a switching device

摘要

The display apparatus of this invention performs a display by modulating the optical characteristics of a display medium. The display apparatus includes: a first substrate; a second substrate facing the first substrate; a display medium interposed between the first and the second substrates; a plurality of bus lines disposed on the first substrate, the bus lines being arranged substantially in parallel to each other in a first direction; a plurality of counter electrodes disposed on the second substrate, the counter electrodes being arranged substantially in parallel to each other in a second direction which is perpendicular to the first direction; arrays of reflection electrodes disposed on the first substrate to substantially completely cover a respective one of the bus lines; and a nonlinear resistive layer mainly made of zinc sulfide and an insulating layer having a through hole which are disposed between each of the bus lines and a reflection electrode in a corresponding one of the reflection electrode arrays, wherein the nonlinear resistive layer is electrically connected to the bus line and the reflection electrode through the through hole, and the nonlinear resistive layer is in a non-conductive state when a voltage of a value smaller than a predetermined value is applied, and is in a conductive state when a voltage of a value equal to or larger than the predetermined value is applied.
