Abstract
A liquid crystal display device capable of dealing with highly definition display and securing both of transmission type display luminance and reflection type display luminance, wherein the Cs on-gate structure is adopted, and a light reflectance is set to be in a range of 1% or more and 30% or less and a light transmittance is set to be in a range of 4% or more and 10% or less on the display panel formed by arranging in matrix a plurality of pixel regions 4 having a reflection region A for reflection type display by reflection of an ambient light and a transmission region B for transmission type display by transmission of light from a light source provided inside.
