Abstract
The reflection-type liquid crystal display device has a pair of substrates disposed opposite to each other and a liquid crystal layer interposed therebetween. A plurality of gate bus wirings and source bus wirings are formed on the surface on the liquid crystal layer side of an insulating substrate composing one substrate to be at right angles to each other and maintain the insulation therebetween. A reflection electrode is formed in the rectangular region formed by the crossing of the gate bus wiring with the source bus wiring. The reflection electrode and the gate bus and source bus wirings are connected through a TFT element. The reflection electrode has a bumpy surface, in the peripheral region of which the ratio of the surface area excluding dents to the total surface area of the peripheral portion of the reflection electrode is selected to be in the range of 60 to 100%.
