Abstract:
A light source optical system includes a micro lens array, a condenser lens unit, and a dichroic surface. In a direction orthogonal to an optical axis in a cross section parallel to a normal of the dichroic surface and the optical axis of the condenser lens unit, a width of the dichroic surface is narrower than a width of the condenser lens unit. A light source optical system satisfies a predetermined conditional expression.

Claim (Index 8):
A projection display apparatus comprising:\n a light source; a positive lens provided in an advancing direction of a light flux from the light source; a wavelength conversion element; a light source optical system configured to guide the light flux from the light source to the wavelength conversion element; an optical modulation element; an illumination optical system configured to illuminate the optical modulation element by using a light flux from the light source optical system; and a color separating and combining system configured to guide the light flux from the light source optical system to the optical modulation element, and guide a light flux from the optical modulation element to a projection optical system, wherein the light source optical system includes: a first lens surface array including a plurality of first lens surfaces; a second lens surface array including a plurality of second lens surfaces and configured to receive a light flux from the first lens surface array; and a condense optical system having a positive power and configured to guide a light flux from the second lens surface array to the wavelength conversion element, wherein the following expression is satisfied: 0.25 < N \u00b7 S LA \u00b7 S LA f LA 2 \ue89e [ mm 2 ] , where the number of the second lens surfaces is defined as N, a focal length of each of the respective second lens surfaces is defined as f LA , and an area of each of the respective second lens surfaces is defined as S LA .
