Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; and a liquid crystal layer provided between the first substrate and the second substrate, wherein: a plurality of picture element regions are each defined by a first electrode provided on one surface of the first substrate and a second electrode provided on the second substrate and opposing the first electrode with the liquid crystal layer therebetween; in each of the plurality of picture element regions, the first electrode includes a solid area formed of a conductive film and a non-solid area with no conductive film provided, the liquid crystal layer is in a vertical orientation state when no voltage is applied between the first electrode and the second electrode, and when a voltage is applied between the first electrode and the second electrode, the liquid crystal layer forms a plurality of first liquid crystal domains each in a radially-inclined orientation at least above the solid area of the first electrode by an inclined electric field generated in the vicinity of the solid area; the plurality of picture element regions each include a transparent region for providing a transmission mode display using light incident in a direction from the first substrate and a reflection region for providing a reflection mode display using light incident in a direction from the second substrate; and in each of the plurality of picture element regions a thickness dr of the liquid crystal layer in the reflection region is smaller than a thickness dt of the liquid crystal layer in the transmission region, wherein the second substrate includes:
