Abstract
In order to realize, at a low cost, the function of an indicator which is brought to a light emitting state during a wait state, a panelas a display section is constituted by self light emitting elements E–Enm for example by organic EL elements, and organic EL elements which function as the indicator Ei which is brought to the light emitting state during the wait state are also formed on the same panel. Meanwhile, an indicator drive circuitwhich drives and allows the organic EL elements that function as the indicator Ei to emit light is constructed by one chip IC together with the data driver. By forming the indicator drive circuitas one chip IC in a data driver, the manufacturing cost can be reduced compared to the case where the indicator drive circuit is prepared separately. The EL elements functioning as the indicator Ei also can be formed on the same substrate as that of the respective EL elements E–Enm constituting the display section by the same process, thereby contributing to cost reduction.
