Liquid crystal display unit and projection display apparatus

A projection display apparatus comprising:

• a light source configured to emit light;
• and
• a liquid crystal display unit configured to modulate the light from the light source;
• the liquid crystal display unit including
• a) a liquid crystal display element configured to modulate the light;
• and
• b) a holder part, having
• a holding portion configured to hold the liquid crystal display element,
• at least one connecting portion formed integrally with the holding portion, and being configured to be connected to a fixing member for fixing a position of the liquid crystal display element,
• an attenuation portion formed in the area from the connecting portion to the holding portion, the attenuating portion attenuating a force transmitting from the connecting portion to the holding portion, and
• a plurality of through-holes formed in the at least one connecting portion, the through-holes including at least one cut-out-through-hole having its part opened, the through-holes being configured to allow insertion of connecting members for connection to the fixing member,
• wherein the at least one cut-out-through hole has an elongated, open-ended shape, and wherein the at least one cut-out-through-hole includes two cut-out-through-holes, the two cut-out-through-holes being disposed only in the connecting portion that is disposed in the first side;
• the holding portion has a first thickness;
• and the attenuation portion is formed in a second thickness smaller than the first thickness;
• the connecting portion is formed in the second thickness to serve as the attenuation portion;
• the second thickness is one-half of the first thickness or smaller.
