Abstract
Transflective-type and reflection type liquid crystal display devices having a high image quality are provided with a good production efficiency.A liquid crystal display device according to the present invention is a liquid crystal display device which includes; a first substrate and a second substrate between which liquid crystal is interposed; a first electrode and a second electrode formed on the first substrate for applying a voltage for controlling an orientation of the liquid crystal; a transistor having an electrode which is electrically connected to the first electrode; a metal layer being formed on the first substrate and including a protrusion, a recess, or an aperture; and a reflective layer formed above the metal layer on the first substrate for reflecting incident light toward a display surface. The metal layer is made of a same material as that of a gate electrode of the transistor. The reflective layer includes a protrusion, a recess, or a level difference which is formed in accordance with a protrusion, a recess, or an aperture of the metal layer.
