| 1. A liquid crystal display device comprising:
a first substrate having a pixel portion with a light reflection portion and a light transmission portion;
a second substrate facing said first substrate with a color filter layer on a side of the substrate facing said first substrate;
a layer thickness difference adjustment layer on said light reflection portion of said first substrate and facing said second
substrate; and
a liquid crystal layer between said first substrate and said second substrate, wherein,
said second substrate includes a first region having said color filter layer and a second region without said color filter
layer,
a step between said first region and said second region results from the presence of the color filter layer in said first
region and the absence of the color filter in the second region,
said thickness difference adjustment layer is positioned to overlap with said second region and adjusts for a thickness difference
of said liquid crystal layer generated by the step, said thickness difference adjustment layer having the same thickness as
that of the color filter layer in the first region.
