Abstract:
The manufacturing yield of transflective liquid crystal display devices is to be enhanced. In a transflective liquid crystal display device including a liquid crystal display panel having a pair of substrates and a liquid crystal layer held between the pair of substrates, the liquid crystal display panel has a plurality of subpixels each having a transmissive part and a reflective part, wherein one of the pair of substrates has: an active element; a first insulating film disposed in a higher layer than the electrode of the active element and having a first contact hole; a counter electrode disposed in a higher layer than the first insulating film; a reflective electrode disposed in the reflective part in a higher layer than the counter electrode; a second insulating film disposed in a higher layer than the counter electrode and the reflective electrode and having a second contact hole; a pixel electrode disposed in a higher layer than the second insulating film; and an electroconductor formed in the first contact hole and electrically connected to the electrode of the active element, and the pixel electrode is electrically connected to the electroconductor via the second contact hole.
