Abstract:
A liquid crystal display device has pixel electrodes including a transmissive pixel electrode and a reflective pixel electrode. The liquid crystal display device includes a TFT array substrate, an opposing substrate, a sealing material that bonds both substrates, an organic film formed on the TFT array substrate and having a thick film portion provided below the pixel electrode and a thin film portion provided outside the thick film portion, a columnar spacer formed on the opposing substrate and holding substrate gap between the both substrates, and a gap retaining pad formed in a region outside the display region and inside the sealing material to adjust the substrate gap outside the display region according to the substrate gap on the pixel electrode. The columnar spacer holds the substrate gap between both substrates over the gap retaining pad and over the pixel electrode.
