A display apparatus, that includes current driving type luminescent elements, has a driving system that takes the conduction types of TFTs to control the emission of the luminescent elements into consideration. In order to reduce driving voltage and improve display quality simultaneously, the arrangement is provided such that if the second TFT (30) which performs the "on-off" function of the current for the luminescent element (40) is of an N channel type, the potential of the common power supply line ("com") is lowered below the potential of the opposite electrode ("op") of the luminescent element (40) to obtain a higher gate voltage ("Vgcur"). In this case, if the first TFT (20) connected to the gate of the second TFT (30) is of a P channel type, when using the potential of the potential-holding electrode ("st") at the "on" state as a reference, potentials of the scanning signal ("Sgate") at the lower potential and the common power supply line ("com") are rendered of the same polarities with respect to this potential of the potential-holding electrode ("st"). Therefore, the potential of the image signal ("data") to turn "on" can be shifted within the range of the driving voltage in the display apparatus (1) in the direction to reduce resistances at the "on" states of the first TFT (20) and the second TFT (30) to reduce driving voltage and improve display quality.

A light flux control member has a back face provided with a recess and a ring-like-recess-portion surrounding the recess. Output light of a point-like-light-source (light emission element) is incident to the recess and the ring-like-recess-portion. Incident light to the recess is emitted from a light control emission face after inner-propagation. Incident light to the ring-like-recess-portion is refracted as to hardly generate inner-propagation light deflected to directions near to a direction of reference optical axis L, resulting in outgoing from any part of the light control emission face, or, if some outgoing occurs from the light control emission face, such outgoing occurs only at an outer periphery portion of the light control emission face. As a result, illumination light quality is avoided from being reduced by appearance of conspicuous ring-like bright part. In addition, uniform illumination light can be supplied to a broad angle range. Even if a plurality of point-like-light-sources are arranged at intervals, respective light fluxes originated from respective point-like-light-sources are well mixed.

An active matrix display device is provided in which parasistic capacitance or the like is suppressed by forming a thick insulating film around an organic semiconductor film, and disconnection or the like does not occur in an opposing electrode formed on the upper layer of the thick insulating film. In the active matrix display device, first, a bank layer composed of a resist film is formed along data lines and scanning lines. By depositing an opposing electrode of a thin film luminescent element on the upper layer side of the bank layer, capacitance that parasitizes the data lines can be suppressed. Additionally, a discontinuities portion is formed in the bank layer. Since the discontinuities portion is a planar section which does not have any a step due to the existence of the bank layer, disconnection of opposing electrode does not occur at this section. When an organic semiconductor film is formed by an ink jet process, a liquid material discharged from an ink jet head is blocked by the bank layer.
