ABSTRACT:
Liquid crystal display panel10is provided with TFT and pixel electrode19, between which interlayer insulator17is interposed, and with reflective section15, in each of a matrix of pixels; having first substrate whereon the pixel electrode19and the TFT's electrode D electrically connect via contact hole20formed in the reflective section15; second substrate whereon at least one protrusions311to313are formed on common electrode in positions corresponding to the each pixel; perpendicular alignment layers deposited on each substrate; and liquid crystal29with negative dielectric anisotropy disposed between substrates. In position corresponding to base of protrusion313provided opposite the second substrate's contact hole20, light-blocking film363is formed so as to cover the base viewed from above. Thus, liquid crystal display panel is provided wherein light leakage from reflective section's contact hole and from protrusions is curbed, with high contrast and display quality.
