    摘要: The liquid crystal display comprises a first substrate 2 including a gate bus line 12a, a data bus line 28, a thin film transistor 18 formed near an intersection between the gate bus line 12a and the data bus line 28, and a pixel electrode 52 including a transmission electrode 32a electrically connected to the thin film transistor 18 and a reflection electrode 48b electrically connected to the transmission electrode 32a; a second substrate 4 opposed to the first substrate 2 and including an opposed electrode 68 opposed to the pixel electrode 52; and a liquid crystal layer 6 sealed between the first substrate 2 and the second substrate 4. The reflection electrode 48b is formed over another gate bus line 12b which is different from the gate bus line 12a, with an insulation layer 40 formed therebetween. The decrease of a voltage applied between the reflection electrode 48b and the opposed electrode 68 can be prevented while the space which can be not used as the transmission region can be utilized. Thus, the area decrease of the transmission part is prevented while the area of the reflection part can be increased, whereby a reflective transmission type liquid crystal display of higher display quality can be provided.
