(54)	Reflective liquid crystal display device

(57) A liquid crystal cell and an external circuit can be connected favorably. The terminal does not require undulated layer and flattened layer. Hence, the reliability of electric connection and physical connection of the terminal and transparent electrode can be enhanced. A reflective liquid crystal display element includes a lower substrate, an undulated layer, a reflective layer, a flattened layer, a transparent electrode, a sealant, a liquid crystal layer, an upper transparent substrate, a liquid crystal cell, a polarizing film, a first birefringent film, a second birefringent film, an external circuit board, and an anisotropic conductive adhesive. It further comprises a liquid crystal cell filling between an upper transparent substrate and lower substrate with liquid crystal, a polarizing film disposed at the upper transparent substrate side of the liquid crystal cell, a birefringent film layer disposed between the polarizing film and liquid crystal cell, and light reflecting means disposed at the lower substrate side of the liquid crystal cell. Undulated layer is not formed in the connection terminal between the lower substrate side of the liquid crystal cell and the external circuit board.
