In this micro mirror array, " dihedral reflector array " is also the member that has utilized following effects: in the time that the light of the one-sided incident from above-mentioned array passes through component side (substrate), this light reflects twice forming between a pair of light reflection surface of each unit optical element (corner reflector), and the light (by light) after twice of this reflection is in the locus imaging of the opposition side (being face symmetry with respect to component side) of above-mentioned array.For example, be shown in Fig. " corner reflector ".) (with reference to patent documentation 1,2). are imaged in to the imaging optic element in space, exploitation has the micro mirror array forming in the upper configuration of substrate (basal disc) multiple " carrying out the unit optical element of the reflection of light being caused by more than one minute surface " of the component side of formation optical element.Wherein, be in array-like arrangement micro mirror array that multiple concavity units optical element or convex unit's optical element form due to simple in structure, estimate that manufacturing cost reduces, therefore receive publicity in recent years, it is vertical with this substrate or with " two mutually orthogonal minute surfaces " (light reflection surface angle of form right angle, a pair of adjacency of the angle configurations close to vertical that this concavity unit's optical element or convex unit's optical element have.I.e.
