Abstract:
A reflective liquid crystal display device comprising:on one of a pair of substrates opposed to each other with a liquid crystal layer interposed therebetween, a plurality of data signal lines for supplying a data signal and a plurality of scanning signal lines for supplying a scanning signal are provided so as to cross each other, a plurality of thin film transistors are provided so as to be electrically connected to the plurality of data signal lines and the plurality of scanning signal lines, a plurality of reflective pixel electrodes are provided on an interlayer insulator formed so as to cover at least a part of the plurality of data signal lines, the plurality of scanning signal lines, or the plurality of thin film transistors, and the plurality of reflective pixel electrodes are electrically connected to corresponding drain electrodes of the plurality of thin film transistors through contact holes provided in the interlayer insulator, wherein an underlying conductive film, provided under substantially an entire region of the interlayer insulator within reflective pixels, comprises at least a portion of at least one drain electrode and is disposed in contact with the interlayer insulator, the underlying film uniformizing heat conduction and/or light transmittance between the interlayer insulator and the one of the substrates and/or contact properties of the interlayer insulator with respect to the one of the substrates in a region where at least one of the plurality of reflective pixel electrodes is formed.
