摘要:
A liquid crystal display panel includes pixels including a reflective region for display in a reflection mode and a transmissive region for display in a transmission mode. The liquid crystal display panel includes a liquid crystal layer including a nematic liquid crystal material having negative dielectric anisotropy and a chiral agent, a pixel electrode including a reflective conductive layer and a transparent conductive layer, a counter electrode, a light diffusing structure provided in common to the reflective region and the transmissive region, and a first vertical alignment film provided between the pixel electrode and the liquid crystal layer, and a second vertical alignment film provided between the counter electrode and the liquid crystal layer. At least one of the first vertical alignment film and the second vertical alignment film has an alignment regulating force defining a pretilt azimuthal direction, and in a case where the thickness of the liquid crystal layer in the reflective region is dr, and the thickness of the liquid crystal layer in the transmissive region is dt, dr and dt are in a range of 0.85≤dt/dr≤1.25.
