Abstract:
1. A reflection type liquid crystal display device comprising: a first substrate and a second substrate opposite said first substrate; a common electrode formed on said second substrate; TFTs each having electrodes, and step structures each formed from the same material as the electrodes of TFTs, being formed on the first substrate, said step structures being formed in the same layer as, and spatially separated from, one of the electrodes of the TFTs, and the step structures having a linear plane shape or a combination of linear plane shapes when seen in plan view; a resin layer formed on said first substrate, the TFTs and the step structures, and having undulation at a surface thereof, and an area with distribution of thermal shrinkage characteristics being different in at least one direction of a thickness direction and a plane direction and being formed according to the TFTs and the step structures, the undulation being formed according to the distribution of thermal shrinkage characteristics within the resin layer; and a reflection layer which is formed on said resin layer and has a surface shape reflecting said undulation of said resin layer, wherein the undulation has a wave-like shape with peak portions thereof being linear or curved, and valley portions thereof having a similar shape to corresponding peak portions when seen looking perpendicular to the plane of the first substrate, and steps are formed in pixel areas according to at least one of number, shape and arrangement of the step structures disposed on the surface of said first substrate under the resin layer, an area having a different distribution of said undulation being formed corresponding to said steps.
