제1관통공(144a)과, 제2관통공(144b)과, 제3관통공(144c)은, 튜브지지블록(144)의 전면(F)과 후면(R)을 관통한다.The first through hole 144a, the second through hole 144b and the third through hole 144c pass through the front surface F and the rear surface R of the tube supporting block 144. [

제1튜브(151)의 일단은, 제1액정탱크(121)와 연결된다. 제1튜브(151)의 타단은, 제1관통공(144a)에 삽입된다. 제1튜브(151)의 타단은, 튜브지지블록(144)의 전면(F)으로부터 돌출된다.One end of the first tube 151 is connected to the first liquid crystal tank 121. The other end of the first tube 151 is inserted into the first through hole 144a. The other end of the first tube 151 protrudes from the front surface F of the tube support block 144.

제2튜브(152)의 일단은, 제2액정탱크(122)와 연결된다. 제2튜브(152)의 타단은, 제2관통공(144b)에 삽입된다. 제2튜브(152)의 타단은, 튜브지지블록(144)의 전면(F)으로부터 돌출된다.One end of the second tube 152 is connected to the second liquid crystal tank 122.
